Shopping Cart Example Code In ASP.NET C# VB.NET GridView

Creating Shopping Cart Example Code In Asp.Net 2.0,3.5,40 With Gridview C#.NET,VB.NET. I'm using GridView and DataList controls to create Products page and Product Details page in online shopping cart example

Create Shopping Cart Example In Asp.Net With GridView


First of all we need to create a ShoppingCart class, for this right click on solution explorer and add new class, name it ShoppingCart.cs
Write this code in ShoppingCart.cs class

namespace ShoppingCartExample
{
    /// <summary>
    /// Summary description for ShoppingCart
    /// </summary>
    [Serializable] 
    public class CartItem
    {
        private int _productID;
        private string _productName;
        private string _imageUrl;
        private int _quantity;
        private double _price;
        private double _subTotal;

        public CartItem()
        { 
        }
        public CartItem(int ProductID, string ProductName, 
              string ImageUrl, int Quantity, double Price)
        {
            _productID = ProductID;
            _productName = ProductName;
            _imageUrl = ImageUrl;
            _quantity = Quantity;
            _price = Price;
           _subTotal = Quantity * Price;
        }
        public int ProductID
        {
            get
            {
                return _productID;
            }
            set
            {
                _productID = value;
            }
        }
         public string ProductName
         {
            get { return _productName; }
            set { _productName = value; }
         }
         public string ImageUrl
         {
             get { return _imageUrl; }
             set { _imageUrl = value; }
         }

         public int Quantity
         {
             get { return _quantity; }
             set { _quantity = value; }
         }

         public double Price
         {
             get { return _price; }
             set { _price = value; }
         }

         public double SubTotal
         {
             get { return _quantity * _price; }
            
         }
    }
    [Serializable]
    public class Cart
    {
        private DateTime _dateCreated;
        private DateTime _lastUpdate;
        private List<CartItem> _items;

        public Cart()
        {
            if (this._items == null)
            {
                this._items = new List<CartItem>();
                this._dateCreated = DateTime.Now;
            }
        }

        public List<CartItem> Items
        {
         get { return _items;}
        set { _items = value;}
        }

        public void Insert(int ProductID, double Price, 
        int Quantity, string ProductName, string ImageUrl)
        {
            int ItemIndex = ItemIndexOfID(ProductID);
            if (ItemIndex == -1)
            {
                CartItem NewItem = new CartItem();
                NewItem.ProductID = ProductID;
                NewItem.Quantity = Quantity;
                NewItem.Price = Price;
                NewItem.ProductName = ProductName;
                NewItem.ImageUrl = ImageUrl;
                _items.Add(NewItem);
            }
            else
            {
                _items[ItemIndex].Quantity += 1;
            }
            _lastUpdate = DateTime.Now;
        }

        public void Update(int RowID, int ProductID, 
                         int Quantity, double Price)
        {
            CartItem Item = _items[RowID];
            Item.ProductID = ProductID;
            Item.Quantity = Quantity;
            Item.Price = Price;
            _lastUpdate = DateTime.Now;
        }

        public void DeleteItem(int rowID)
        {
            _items.RemoveAt(rowID);
            _lastUpdate = DateTime.Now;
        }

        private int ItemIndexOfID(int ProductID)
        {
            int index = 0;
            foreach (CartItem item in _items)
            {
                if (item.ProductID == ProductID)
                {
                    return index;
                }
                index += 1;
            }
            return -1;
        }

        public double Total
        {
            get
            {
                double t = 0;
                if (_items == null)
                {
                    return 0;
                }
                foreach (CartItem Item in _items)
                {
                    t += Item.SubTotal;
                }
                return t;
            }
        }
 
    }
}

Now to create Products page, add a new webform and name it Products.aspx, add sqldataSource and configure it for select statement,
read this for how to configure SqlDataSource
Add a DataList Control on the page and make SqlDataSource1 it's source.
Configure Datalist according to below mentioned source
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<div>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT [ProductID], [Name], [Description], 
               [Price], [ImageUrl] FROM [Products]">
</asp:SqlDataSource>
</div>

<asp:DataList ID="DataList1" runat="server" 
              DataSourceID="SqlDataSource1" 
              RepeatColumns="4"
              RepeatDirection="Horizontal">
<ItemTemplate>
<asp:ImageButton ID="ImageButton1" runat="server" 
ImageUrl='<%# Eval("ImageUrl", "Images\\thumb_{0}") %>' 
PostBackUrl='<%# Eval("ProductID", 
"ProductDetails.aspx?ProductID={0}") %>' />
<br />
<asp:Label ID="NameLabel" runat="server" 
           Text='<%# Eval("Name") %>'>
</asp:Label>
<asp:Label ID="PriceLabel" runat="server" 
           Text='<%# Eval("Price", "{0:C}") %>'>
</asp:Label><br />
<br />
<br />
</ItemTemplate>
</asp:DataList><br />
<asp:HyperLink ID="CartLink" runat="server" 
               NavigateUrl="~/UserCart.aspx">
               View Shopping Cart
</asp:HyperLink><br />
</form>

Now add a new webform and name it ProductDetails.aspx , this page is used for showing details for selected product from product catalog page, again add a SqlDataSource and DataList Control on this page and configure them according to source shown below, this time datalist is populated using QueryString Parameters.
<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT [ProductID], [Name], [Description], 
               [Price], [ImageUrl] FROM [Products] 
               WHERE ([ProductID] = @ProductID)">
    <SelectParameters>
    <asp:QueryStringParameter Name="ProductID" 
                              QueryStringField="ProductID" 
                              Type="Decimal" />
    </SelectParameters>
</asp:SqlDataSource>
</div>

<asp:DataList ID="DataList1" runat="server" 
              DataSourceID="SqlDataSource1">
<ItemTemplate>
  <asp:Image ID="Image1" runat="server" 
       ImageUrl='<%# Eval("ImageUrl","~/Images\\{0}") %>'/>
  <asp:Label ID="ImageUrlLabel" runat="server" 
             Text='<%# Eval("ImageUrl") %>' 
             Visible="False">
  </asp:Label><br />
  <asp:Label ID="NameLabel" runat="server" 
             Text='<%# Eval("Name") %>'>
  </asp:Label><br />
  <asp:Label ID="DescriptionLabel" runat="server" 
             Text='<%# Eval("Description") %>'>
  </asp:Label><br />
  <asp:Label ID="PriceLabel" runat="server" 
             Text='<%# Eval("Price", "{0:##0.00}" ) %>'>
  </asp:Label><br />
</ItemTemplate>
</asp:DataList><br />
<asp:Button ID="btnAdd" runat="server" OnClick="Button1_Click" 
                        Text="Add to Cart" /><br /><br />
<asp:HyperLink ID="HyperLink1" runat="server" 
               NavigateUrl="~/Products.aspx">
               Return to Products Page
</asp:HyperLink>
Write this code in C# code behind of ProductDetails.aspx page
protected void Button1_Click(object sender, EventArgs e)
{
  double Price = double.Parse(((Label)
    DataList1.Controls[0].FindControl("PriceLabel")).Text);
  string ProductName = ((Label)
    DataList1.Controls[0].FindControl("NameLabel")).Text;
  string ProductImageUrl = ((Label)
   DataList1.Controls[0].FindControl("ImageUrlLabel")).Text;
int ProductID = int.Parse(Request.QueryString["ProductID"]);
if (Profile.SCart == null)
{
  Profile.SCart = new ShoppingCartExample.Cart();
}
  Profile.SCart.Insert
      (ProductID, Price, 1, ProductName, ProductImageUrl);
  Server.Transfer("Products.aspx");
}

Now right click on solution explorer and add new web user control, name it CartControl.ascx
In design view of this control add a new GridView control and a label below gridview, html shource of this control should look like this
<%@ Control Language="C#" AutoEventWireup="true" 
            CodeFile="CartControl.ascx.cs" 
            Inherits="CartControl" %>
<asp:GridView ID="grdCart" runat="server" 
              AutoGenerateColumns="False" 
              DataKeyNames="ProductID" 
              OnRowCancelingEdit="grdCart_RowCancelingEdit" 
              OnRowDeleting="grdCart_RowDeleting" 
              OnRowEditing="grdCart_RowEditing" 
              OnRowUpdating="grdCart_RowUpdating">
<Columns>
<asp:TemplateField>
    <ItemTemplate>
    <asp:Image ID="Image1" runat="server" 
    ImageUrl='<%#Eval("ImageUrl","~/Images/thumb_{0}")%>'/>
    </ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="ProductName" 
                HeaderText="Product" ReadOnly="True"/>
<asp:BoundField DataField="Quantity" HeaderText="Quantity"/>
<asp:BoundField DataField="Price" DataFormatString="{0:c}" 
                HeaderText="Price" ReadOnly="True" />
<asp:BoundField DataField="SubTotal" DataFormatString="{0:c}" 
                HeaderText="Total" ReadOnly="True" />
<asp:CommandField ShowDeleteButton="True" 
                  ShowEditButton="True"/>
</Columns>
<EmptyDataTemplate>
Your Shopping Cart is empty, add items
<a href="Products.aspx">Add Products</a>
</EmptyDataTemplate>
</asp:GridView>
<asp:Label ID="TotalLabel" runat="server"></asp:Label>

Open web.config file and add this section for enabling anonymous users to add items to cart

<system.web>
  <authorization>
   <allow users="?" />
   <allow roles="admin" />
  </authorization>
  <roleManager enabled="true" />
  <authentication mode="Forms" />
          <compilation debug="true">
            </compilation>
        </system.web>
  <system.web>
    <anonymousIdentification enabled="true"/>
    <profile enabled="true">
      <properties>
       <add name="SCart" serializeAs="Binary" 
            type="ShoppingCartExample.Cart" 
            allowAnonymous="true"/>
      </properties>
    </profile>
  </system.web>

Now go to code behnd of CartControl.ascx and write this code
protected void Page_Load(object sender, EventArgs e)
    {
        if (Profile.SCart == null)
        {
            Profile.SCart = new ShoppingCartExample.Cart();
        }
        if (!Page.IsPostBack)
        {
            ReBindGrid();
        }
        if(Profile.SCart.Items == null)
        {
            TotalLabel.Visible = false;
        }
    }
    protected void grdCart_RowEditing
                 (object sender, GridViewEditEventArgs e)
    {
        grdCart.EditIndex = e.NewEditIndex;
        ReBindGrid();
    }
    protected void grdCart_RowUpdating
               (object sender, GridViewUpdateEventArgs e)
    {
        TextBox txtQuantity = (TextBox)
        grdCart.Rows[e.RowIndex].Cells[2].Controls[0];
        int Quantity = Convert.ToInt32(txtQuantity.Text);
        if (Quantity == 0)
        {
            Profile.SCart.Items.RemoveAt(e.RowIndex);
        }
        else
        {
            Profile.SCart.Items[e.RowIndex].Quantity 
                                         = Quantity;
        }
        grdCart.EditIndex = -1;
        ReBindGrid();
    }
    protected void grdCart_RowCancelingEdit
             (object sender, GridViewCancelEditEventArgs e)
    {
        grdCart.EditIndex = -1;
        ReBindGrid();
    }
    protected void grdCart_RowDeleting
                 (object sender, GridViewDeleteEventArgs e)
    {
        Profile.SCart.Items.RemoveAt(e.RowIndex);
        ReBindGrid();
    }
    private void ReBindGrid()
    {
        grdCart.DataSource = Profile.SCart.Items;
        DataBind();
        TotalLabel.Text = string.Format("Total:{0,19:C}", 
                                     Profile.SCart.Total);
    }

Now add Global Application Class (Global.asax) by right clicking on solution explorer > add new Item. and write code mentioned below in it.
void Profile_OnMigrateAnonymous(object sender, ProfileMigrateEventArgs e)
    {
        ProfileCommon anonymousProfile = Profile.GetProfile(e.AnonymousID);
        if (anonymousProfile.SCart != null)
        {
            if (Profile.SCart == null)
                Profile.SCart = new ShoppingCartExample.Cart();

            Profile.SCart.Items.AddRange(anonymousProfile.SCart.Items);

            anonymousProfile.SCart = null;
        }

        ProfileManager.DeleteProfile(e.AnonymousID);
        AnonymousIdentificationModule.ClearAnonymousIdentifier();
    }
       


Add another webform and name it UserCart.aspx, in design view of this page drag the CartControl we've just created and put a hyperlink for going back to products cataloge page

Tha's it , build and run the application
Have fun

How to solve this error ???
"The name 'Profile' does not exist in the current context..."
TQ


amiT jaiN said...

@ anonymous :

have you added blow code in web.config file ?
<system.web>
<anonymousIdentification enabled="true"/>
<profile enabled="true">
<properties>
<add name="SCart" serializeAs="Binary"
type="ShoppingCartExample.Cart"
allowAnonymous="true"/>
</properties>
</profile>
</system.web>


hanuman said...

it never works sometimes profile does not exists (even i added this section to web config), sometimes some other problems.
Any code which i can get for cart to remove & edit items -getting data from a sql stored procedure .I am using table control for shoping cart & dynamically adding items .But not able to remove or edit perticular row in the table.


Bhanu said...

Is this code meant to run on vs2005 or vs2008?

and the code download link doesn't work.

in VS2008 i get the error "The name 'Profile' does not exist in the current context..." in spite of adding the lines to web.config.

in vs2005 i get the following error.
Error 1 The type or name space name 'List' could not be found (are you missing a using directive or an assembly reference?)


amiT jaiN said...

@ anonymous , hanuman and Bhanu :
I've fix the download link, download the source code , run it and do let me know if you face any further problem @ Bhanu : i've created this example using VS.NET 2005 but it should run on 2008 as well without any errors , download the source from the download link

amiT


Bhanu said...

Here are couple of errors that i got with the source i downloaded.
I am using VS2005. I created a Asp web application named ShoppingCartExample and copied your source to it and created a new sql data connection based on the fields u have mentioned i had already created a database and table on those fields.

I got total of 24 errors.

Error 1 ScriptManager1:Unknown server tag 'asp:ScriptManager
Error 2 The name 'DataList1' does not exist in the current context
Error 5 The name 'Profile' does not exist in the current context
Error 7 The type or namespace name 'Cart' does not exist in the namespace 'ShoppingCartExample' (are you missing an assembly reference?)
Error 13 The name 'TotalLabel' does not exist in the current context
Error 14 The name 'grdCart' does not exist in the current context

I will try on VS2008 now and see if it works


amiT jaiN said...

@Bhanu:

1 . I created this application with asp.net ajax extensions installed, you either create new AJAXEnabled website after installing ajax extensions or simply remove the script manager by going to design view and delete script manager

2. Check name of datalist control you've put on the Products page
asp:DataList ID="DataList1" runat="server"
DataSourceID="SqlDataSource1"
RepeatColumns="4"
RepeatDirection="Horizontal

For other errors check what namespace u've written in the class file in my case it's ShoppingCartExample

Add "using ShoppingCartExample" in the code behind of page


Bhanu said...

I tried it on VS2008 also petty much the same error.

1. I removed script manager.

2. I am using the same name DataList1, i didn't change ur code at all, other than configuring data source.

3. I am using the same name space as your.
but still i have issues.

Why don't you upload the complete project with .csproject file also.


amiT jaiN said...

@Bhanu: I really not able to find out why are you getting these errors

Check your Class file , and than check whether have u provided a namespace to it (u'll have to as it's not default like this

namespace ShoppingCartExample
{
Your class code
}

Any way i've uploaded a new source without ajax and with solution file and csproject file

http://www.box.net/shared/t9fq0i4x7b

Download and let me know whether it solves ur errors or not


Bhanu said...

I don't know what is the issue but i am still get the same error messages.
Did anyone else try it?


amiT jaiN said...

@bhanu :

Can you please send me your code, so that i can look into and try to fix the errors

send me ur code in zip format to jainamit.agra@gmail.com

regards


hanuman said...

Download link is not working for me & this code is v. imp for me .Please help


amiT jaiN said...

@hanuman:

you can download the source code from this link

Click here to download


hanuman said...

sorry for trouble , but This is a .rar extension file , i am unable to open on my computer.Please help again .


amiT jaiN said...

@hanuman:

You need to download and install winrar to open .rar files

alternatively download zip file from here .


hanuman said...

thanks a lot !Can you please also help me in this error-appreciate it!
It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.


amiT jaiN said...

@hanuman:

This error is caused for two reasons

1. Chekc whether u r having two web.config files in ur application ? , if yes than remove one

2. This error also occurs if u have not opened the website from the folder containing the aspx files and all files but from one folder up like this

ShoppingCartNew > shoppingCart > All files

If u browse and open ShoppingCartNew, u'll get allowDefinition='MachineToApplication' error

Open shoppingCart and u'll prolly not get this error

hope this helps

I'm getting this error:

"Make sure that the class defined in this code file matches the 'inherits' attribute, and that it extends the correct base class(e.g Page or UserControl)."

I get this erro in this line:

public partial class CartControl : System.Web.UI.Page

In this page i have in inherits:

"CodeFile="CartControl.ascx.cs"
Inherits="CartControl"

I can't see the problem, can someone help?

I'm new in asp.net


amiT jaiN said...

@Anonymous:

Change

public partial class CartControl : System.Web.UI.Page

to

public partial class CartControl : System.Web.UI.UserControl


And error will be gone


hanuman said...

Thanks a lot! it's a great code ,Question when i use ur downloaded code Profile does not give error but when i use same code creating seperate web application project Profile -does not exists error comes , even if i use Profile section in web config . file.
So are u using some reference or web reference for Profile?Please clarify for me to write code in future.


amiT jaiN said...

@Hanuman:

You must be missing something in ur code
Check all the namespaces in ur code behinds with mine

Check whether u have ASPNETDB.MDF database in ur App_Code folder , it should be created autometically when u enable profile in web.config


Anonymous said...

The profile requires a SQL Express database connection locally or the .MDF database you mentioned above. My App_Code folder does not have the ASPNETDB.MDF database in it even after I have added the profile section to my web.config. I keep getting "cannot connect to SQL database" errors when the debugger hits the profile.SCart calls because of this. How do we add the .MDF file manually??


amiT jaiN said...

@Anonymous:

Open your application in Visual Studio.
Click on Website menu > ASP.NET Configuration
Follow the steps and it should configure and create ASPNET database

Alternatively you can try adding ASPNET database froom my application

For this right click on App_Code folder > add existing Item >Browse to ASPNET.mdf > click on add

I downloaded this code changed products data to my datatable , changed some CSS in grid ,I am doing it using "WebApplication" Not Web Site .No Error came not even for Profile as there is a MDB file sitting there in App_code folder when i downloded Jain's code ,if you are creating a new web application just copy & paste Both MDB file in your Appcode folder & set profile section in web config. Trust me it will work . It's nice code solved my problems & time too .
If you need some code i can send you my old shopping cart code in which i am using table control for cart items , but not able to remove & edit items .

amiT jaiN said...

@suba :

Please check whether you have below mentioned code in your class file or not ?

public void Insert(int ProductID, double Price,
int Quantity, string ProductName, string ImageUrl)
{
int ItemIndex = ItemIndexOfID(ProductID);
if (ItemIndex == -1)
{
CartItem NewItem = new CartItem();
NewItem.ProductID = ProductID;
NewItem.Quantity = Quantity;
NewItem.Price = Price;
NewItem.ProductName = ProductName;
NewItem.ImageUrl = ImageUrl;
_items.Add(NewItem);
}
else
{
_items[ItemIndex].Quantity += 1;
}

hanuman said...

Hi Amit
I am using your code but the official requirement is now with every item in the cart they can have associated Name of the person, Address, phone & location code. I added these fields in the shopping cart items and on AddToCart button storing information in two seperate datatables one item ,quantity etc. another person name ,address,phone etc. related & created nested gridview on productid ,on productid + click it gives child gridview which has related information of the parent gridview (parent has all itemchild has person name,address etc.).My question is that how can i create nested gridview like grdcart.datasource =Profile.Scart.item
in which the child gridview will have only the related Address ,name ,phone etc with productID.
with editable child gridview.AS I do not want to create datatables the way i did today & loose the beauty of Profile.cart option.Please help....


hanuman said...

can i have a nested gridview with profile with each item containing related persons name ,address location & phone numbers. As in the same page order can go to different persons .


amiT jaiN said...

@hanuman:

Hi you can achieve this thing by putting a Detailsview in usercontrol we created ,

1. Set the DataKeyNames property of GridView (grdCart) to ProductID.

2. Set ShowSelectButton property of gridview to true.

now write below mentioned code in html source of page

<asp:DetailsView ID="DetailsView1" runat="server" Height="50px" Width="125px" AutoGenerateRows="False" DataSourceID="SqlDataSource1">
<Fields>
<asp:BoundField DataField="ProductID" HeaderText="ProductID" SortExpression="ProductID" />
<asp:BoundField DataField="OrderNo" HeaderText="OrderNo" SortExpression="OrderNo" />
<asp:BoundField DataField="CustomerName" HeaderText="CustomerName" SortExpression="CustomerName" />
</Fields>
</asp:DetailsView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT [ProductID], [OrderNo], [CustomerName] FROM [Details] WHERE ([ProductID] = @ProductID)">
<SelectParameters>
<asp:ControlParameter ControlID="grdCart" Name="ProductID" PropertyName="SelectedValue"
Type="Decimal" />
</SelectParameters>
</asp:SqlDataSource>

I've created a sample for you which you can download from here

Do let me know whether it solves your query or not ?

Hi. Am doing a project called as online shopping. I need to add items in cart which is stored in database, how ll i do it?


amiT jaiN said...

@dceblog:

1.If you want to create a new database than right click in solution explorer in Visual studio > select add new item > select SQL database from list, now you can create tables in this database in similar way we create in sql server.

2.If you want to add a database.mdf file from a database created in sql server than

right click on databse name in sql server management studio and select detach

Copy the databaseName.mdf and databaseName_Log files from sql server installation directory (usually C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data) to desktop

Now right click on solution explorer in Visual studio > select Add existing item > browse to databsename.mdf on desktop > click ok
Done

I added the shopping cart to my project and it works great.
But I raninto a situation that when the customer want to proceed to check out , I transfer the to a login page, after login, the user should see the cart items and then pay, but somehow, after user login, the cart is empty.
And before login, the cart have 2 items.
I am not familier with the profile, would you please help me? is it something to do with the configuration? thanks a lot..

Is this database cart


orangge said...

Hi:
Currently i'm doing a Shopping Cart for my project. It's created in asp.net 2.0 with vb. There are 3 conditions (as below) which i need to apply in :

1) Visitors Cart
Every visitor to our online shop will be given a 'Visitors Cart'. This allows the visitor to store their products in a temporary shopping cart. Once the visitor leaves the online shop, so will the contents of their shopping cart.

2) Members Cart
Every member to our online shop that logs in is given a 'Members Cart'. This allows the member to add products to their shopping cart, and come back at a later date to finalize their checkout. All products remain in their shopping cart until the member has checked them out, or removed the products themselves.

3) Info
If a member adds products to their 'Visitors Cart' and decides to log in to the online shop to use their 'Members Cart', the contents of their 'Visitors Cart' will merge with their 'Members Cart' contents automatically.


So, i'm wondering do i need to use the Session to store the Visitors Cart info and create a Member Cart table (which i already created in my sql server 2000 database) to store the Members Cart info or can use the Profile to store the info. I'm kind of confused because i'm new in asp.net 2.0.

Urgently needed help. Thanks in advanced.

Hi mate,
I realized that you used Profile to store anonymous user to add items to the shopping cart. Your code works great. However using profile means when a user re-visits this web, it will remind them of un-purchased items. But for most of e-commerce website, any un-purchased items should be deleted when user's session times out, otherwise the server will just keep tracking of a large amount of anonymous users and their items. Is there anyway to empty the Profile when user's session is timed out?

This is really a cool web applet.
But I dont know why cart is not empty when I close the session and open a new session. Means though I'm a Anonymous user, when ever I load the page, it shows items already in the cart.

So to fix this I have implemented my own codes. Maybe this wont be good as the original programmer has did.

Anyway have a look on my fix:

Put this on your Product Page Server side load event:
if (this.Session.IsNewSession == true)
{
clearCart();
}

Also Below Load Event, Write this:
private void clearCart() {

if (Profile.SCart.Items.Count == 0) { }
else
{

int i = 0;
try
{
do
{
Profile.SCart.DeleteItem(i);
i++;


} while (Profile.SCart.Items.Count > 0);

}
catch
{
Profile.SCart.DeleteItem(0);
}

}

}

Hope you have got a solution for that problem!

The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.

Hi.
I was building a shopping cart in asp.net and this code really helped me out.

However,
after editing and updating the quantity of an item, it didn't update the changed quantity from the text box. It remains as the previous item quantity value (as what is displayed when the page was loaded).

When I debugged the code, I found out that the error is in the value inside the following textbox as in the original code. The textbox still holds the old value even though the text is already overwritten in the display.

----------------------------------------------
TextBox txtQuantity = (TextBox)
grdCart.Rows[e.RowIndex].Cells[2].Controls[0];
int Quantity = Convert.ToInt32(txtQuantity.Text);
-----------------------------------------------

I have tried a number of other ways but couldn't solve the problem. Do you have any solution regarding this problem? Thanks.

Hello:

I have a question:

how i can do to empty the shopping cart, once i leave the navigator?


Anonymous said...

This cart works great for me. How would you handle shipping though? For example, if I wanted to do something like a single flat rate $10 shipping charge for international, but $0 for domestis using a drop down list, how can you integrate this?


Anonymous said...

Sir,
i have an error how i should handle this.i work from last 4 month on shopping cart.its my graet pleasure that u provide us.please please please help me.

It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.

amiT jaiN said...

@wasiq:

This error is caused for these reasons

1. Chekc whether u r having two web.config files in ur application ? , if yes than remove one, web.config file should be directly under virtual directory.

2. This error also occurs if u have not opened the website from the folder containing the aspx files and all files but from one folder up like this

ShoppingCartNew > shoppingCart > All files

If u browse and open ShoppingCartNew, u'll get allowDefinition='MachineToApplication' error

Open shoppingCart and u'll prolly not get this error

3. Remove any backup folders if you have which may contain web.config file.

4. If you have not Configured your application to run on IIS then Create a virtual directory and assign permissions to Application (Read,Write).

But above all make sure to check existance of more then one web.config files any backup folders or in any other folder


hope this helps

Balaji Mitkari said...

Error 1 The type or namespace name 'List' could not be found (are you missing a using directive or an assembly reference?)

Error 2 The type or namespace name 'List' could not be found (are you missing a using directive or an assembly reference?)

What to do?


amiT jaiN said...

@Balajiv:

You need to add namespace to use List

Using System.Collections.Generic

I used your code it is working when i run it offline(on local host) but when i upload the files on server then it shows some database connection error


amiT jaiN said...

@Above: you need to change connection string in web.config according to sql server name and address of your host, and you may also need to take care of ASPNETDB.mdf
