blogger page views post view hit counter to count views of post/page

Page post view or post views hit counter to count how many times any post or article on blogspot blog has been read.

Several times bloggers like to count how many times any post or articles on blog has been read.

But blogger doesn't provide any way for counting page views or any post hit counter widget

I've written a hit counter script for blogspot bloggers to count page / post views or hits and sharing it with everyone who needs it



to put page views counter in all posts of your blog , follow these steps

Just click on button below to add this counter

<a href="http://csharpdotnetfreak.blogspot.com/2009/02/blogger-post-page-views-hit-counter.html"><script src="http://www.amitjain.co.in/pageview.php" type="text/javascript"/></script></a>

Second Method.

1. Login to Blogspot -> Dashboard -> Layout -> Edit HTML

2. click on expend widget Templates

3. find below mentioned line of code

<p><data:post.body/></p>

Now paste below mentioned code above this line

<b:if cond='data:blog.pageType == &quot;item&quot;'>
<div id='hit-counter'>
&lt;a href=&#39;http://csharpdotnetfreak.blogspot.com&#39; rel=&#39;follow&#39;&gt;
<script src='http://www.amitjain.co.in/pageview.php' type='text/javascript'/> &lt;/a&gt;
</div></b:if>

4. Save your template

Third Method.

If you don't want to edit html code than you can put this counter in sidebar of your blog.

For this Go to Layout > Click on Add a Gadget

Select HTML/Javascript

Now copy and paste below mentioned code in the box

<a href="http://csharpdotnetfreak.blogspot.com/2009/02/blogger-post-page-views-hit-counter.html"><script src='http://www.amitjain.co.in/pageview.php' type='text/javascript'/></a>

Click on Save.

Test the post views counter, leave me a comment if you like it or having any problems in installing it


Have fun

Failed to access IIS metabase ASP.NET

If You are getting "Failed to access IIS metabase" error while browsing asp.net site or aspx page in IIS server then you may have installed IIS Server after installing the .NET framework.

If that's the case, try running to repair your ASP.NET installation and set up all of the appropriate ISAPI extension mappings.


Open visual studio command prompt and type this command

aspnet_regiis -ga <UserName>

if this doesn'twork than use this command

aspnet_regiis -i

alternatively you can copy and paste this command into windows command prompt

%windir%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i

this will fix your problem

C# Forms Authentication using ticket and managing user roles in asp.net

In this article i am going to describe how to implement Forms authentication using tickets and managing roles based access in ASP.NET using C#



For implementing forms authentication without using formsauthentication ticket, read my previous article - Forms Authentication with C# and managing folder lavel access with multiple web.config files



Configuring web.config file in application root

<authentication mode="Forms">
<forms defaultUrl="Default.aspx" loginUrl="~/Login.aspx"
slidingExpiration="true" timeout="20"></forms>
</authentication>

Defining roles and accessibility in root web.config

<location path="Admin">
<system.web>
<authorization>
<allow roles="admin"/>
<deny users="*"/>
</authorization>

</system.web>

</location>

Defining roles settings for folders and aspx within those folders in web.config file in those folders

<system.web>
<authorization>
<allow roles="user"/>
<deny users="*"/>
</authorization>
</system.web>

settings for any logged in member

<system.web>
<authorization>
<deny users="?"/>
</authorization>

Now after creating Login page we need to authenticate user

protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
{
string userName = Login1.UserName;
string password = Login1.Password;
bool rememberUserName = Login1.RememberMeSet;

//Fetch User login information fromthe xml file into Dataset

string xmlFilePath = Server.MapPath("~/App_Data/LoginInfo.xml");
DataSet objDs = new DataSet();
objDs.ReadXml(xmlFilePath);
DataRow[] dRow = objDs.Tables[0].Select("UserName = '" + userName + "' and Password = '" + password + "'");
if (dRow.Length > 0)
{
//Fetch the role
string roles = dRow[0]["Roles"].ToString();

//Create Form Authentication ticket
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1, userName, DateTime.Now, DateTime.Now.AddMinutes(20), rememberUserName, roles, FormsAuthentication.FormsCookiePath);

// In the above parameters 1 is ticket version, username is the username associated with this ticket
//time when ticket was issued , time when ticket will expire, remember username is user has chekced it
//roles associted with the user, and path of cookie if any

//For security reasons we may hash the cookies
string hashCookies = FormsAuthentication.Encrypt(ticket);
HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, hashCookies);

// add the cookie to user browser

Response.Cookies.Add(cookie);

// get the requested page

string returnUrl = Request.QueryString["ReturnUrl"];
if (returnUrl == null)
returnUrl = "~/Default.aspx";
Response.Redirect(returnUrl);
}

Now to retrieve the authentication and roles information on every request we need to write this code in Global.asax file

protected void Application_AuthenticateRequest(object sender, EventArgs e)
{
// look if any security information exists for this request

if (HttpContext.Current.User != null)
{

// see if this user is authenticated, any authenticated cookie (ticket) exists for this user

if (HttpContext.Current.User.Identity.IsAuthenticated)
{

// see if the authentication is done using FormsAuthentication

if (HttpContext.Current.User.Identity is FormsIdentity)
{

// Get the roles stored for this request from the ticket

// get the identity of the user

FormsIdentity identity = (FormsIdentity)HttpContext.Current.User.Identity;

//Get the form authentication ticket of the user

FormsAuthenticationTicket ticket = identity.Ticket;

//Get the roles stored as UserData into ticket

string[] roles = ticket.UserData.Split(',');

//Create general prrincipal and assign it to current request

HttpContext.Current.User = new System.Security.Principal.GenericPrincipal(identity, roles);
}
}
}
}

To check whether user in in the role or not we need to write this code in every page which provide access on role basis

protected void Page_Load(object sender, EventArgs e)
{
if (HttpContext.Current.User.IsInRole("admin"))
{
lblMessage.Text = "Welcome Administrator";
}
}

Ajax Cascading DropDownList With Database Example in GridView

There are several cases when you have two or three dropdowns in gridview and want second one (and third one) to be populated based on selection of first and second dropdownlist.

In this example i've implemented Ajax cascading drop down list in EditItemTemaplete of GridView for updation of records in grid by fetching data from database to populate dropdowns,I've also implemented ajax auto complete extender textbox in it to edit name field

Make sure you have created ajax enabled website and installed ajax toolkit and ajax web extensions properly

In this example gridview displays Name, City, and Country on page load,

And City and Country field turns into cascading dropdown list when user clicks on Edit link

Ajax cascading dropdown extender uses webservice to fetch data from database and populate dropdowns, city dropdown is populated based on country selected in country dropdown

Important points to remember

1. Put AjaxControlToolkit.dll in bin folder of your application.
2. Set EventValidation to false in page directive of your aspx page

<%@ Page Language="C#" EnableEventValidation="false"
AutoEventWireup="true" CodeFile="Default.aspx.cs"
Inherits="_Default" %>

Here is explanation why you need to turn it off ?
in order for the values to be submitted, EventValidation needs to be disabled for the page. EventValidation ensures that the values in each control match the values that were present when the page was rendered, but since these drop downs are populating on the client side, this is never true.

3. If you are getting Error method 500 or 12031 than read this to resolve this error

4. Webservice must have the webmethod with following signature and exact parameters

[WebMethod]
public CascadingDropDownNameValue[] GetColorsForModel(
string knownCategoryValues,
string category)

You can change the method name but return type must be CascadingDropDownNameValue[] with knownCategoryValues,category as parameters

First of all add a new webservice and name it CascadingDropDown.asmx
In code behind of this asmx file write following code
Add these namespaces

using System.Collections.Generic;
using System.Configuration;
using System.Data.SqlClient;
using AjaxControlToolkit;
using System.Collections.Specialized;

/// <summary>
/// Summary description for CascadingDropDown
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.Web.Script.Services.ScriptService()]
public class CascadingDropDown : System.Web.Services.WebService
{
//Create global Connection string
string strConnection = ConfigurationManager.ConnectionStrings
["dbConnectionString"].ConnectionString;

public CascadingDropDown () {

//Uncomment the following line if using designed components 
//InitializeComponent(); 
}
/// <summary>
/// WebMethod to populate country Dropdown
/// </summary>
/// <param name="knownCategoryValues"></param>
/// <param name="category"></param>
/// <returns>countrynames</returns>
[WebMethod]
public CascadingDropDownNameValue[] GetCountries
(string knownCategoryValues, string category)
{
//Create sql connection and sql command
SqlConnection con = new SqlConnection(strConnection);
SqlCommand cmd = new SqlCommand();
cmd.Connection = con;
cmd.CommandType = System.Data.CommandType.Text;
cmd.CommandText = "Select * from Country";

//Create dataadapter and fill the dataset
SqlDataAdapter dAdapter = new SqlDataAdapter();
dAdapter.SelectCommand = cmd;
con.Open();
DataSet objDs = new DataSet();
dAdapter.Fill(objDs);
con.Close();

//create list and add items in it 
//by looping through dataset table
List<CascadingDropDownNameValue> countryNames
= new List<CascadingDropDownNameValue>();
foreach (DataRow dRow in objDs.Tables[0].Rows)
{
string countryID = dRow["CountryID"].ToString();
string countryName = dRow["CountryName"].ToString();
countryNames.Add(new CascadingDropDownNameValue
(countryName, countryID));
}
return countryNames.ToArray();


}

[WebMethod]
public CascadingDropDownNameValue[] GetCities
(string knownCategoryValues, string category)
{
int countryID;
//this stringdictionary contains has table with key value
//pair of cooountry and countryID
StringDictionary countryValues =
AjaxControlToolkit.CascadingDropDown.
ParseKnownCategoryValuesString(knownCategoryValues);
countryID = Convert.ToInt32(countryValues["Country"]);

SqlConnection con = new SqlConnection(strConnection);
SqlCommand cmd = new SqlCommand();
cmd.Connection = con;
cmd.CommandType = System.Data.CommandType.Text;
cmd.Parameters.AddWithValue("@CountryID", countryID);
cmd.CommandText =
"Select * from City where CountryID = @CountryID";

SqlDataAdapter dAdapter = new SqlDataAdapter();
dAdapter.SelectCommand = cmd;
con.Open();
DataSet objDs = new DataSet();
dAdapter.Fill(objDs);
con.Close();
List<CascadingDropDownNameValue> cityNames =
new List<CascadingDropDownNameValue>();
foreach (DataRow dRow in objDs.Tables[0].Rows)
{
string cityID = dRow["CityID"].ToString();
string cityName = dRow["CityName"].ToString();
cityNames.Add(new CascadingDropDownNameValue
(cityName, cityID));
}
return cityNames.ToArray();
}

}

Now in html source of aspx page I've put two dropdowns in EditItemTemaplate of gridview

<EditItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server">
</asp:DropDownList><br />
<ajaxToolkit:CascadingDropDown ID="CascadingDropDown1"
runat="server"
Category="Country"
TargetControlID="ddlCountry"
PromptText="-Select Country-"
LoadingText="Loading Countries.."
ServicePath="CascadingDropDown.asmx"
ServiceMethod="GetCountries">
</ajaxToolkit:CascadingDropDown>
</EditItemTemplate>

Here TargetControlID is id of dropdown on which cascading dropdown is to be implemented ,Service path is path to webservice and ServiceMethod is method to fetch the data from databse and populate dropdown

You also need to add reference to webservive in script manager

<asp:ScriptManager ID="ScriptManager1" runat="server">
<Services>
<asp:ServiceReference Path="CascadingDropDown.asmx" />
</Services>
</asp:ScriptManager>

The complete html source is like this

<%@ Page Language="C#" EnableEventValidation="false"
AutoEventWireup="true" CodeFile="Default.aspx.cs"
Inherits="_Default" %>

</asp:TemplateField>

<asp:TemplateField HeaderText="City"

<EditItemTemplate>
<asp:DropDownList ID="ddlCity" runat="server"

</ContentTemplate>
</asp:UpdatePanel>
<div>

<asp:SqlDataSource ID="SqlDataSource1" runat="server"

<asp:Parameter Name="Country"/>
<asp:Parameter Name="City"/>
</UpdateParameters>
</asp:SqlDataSource>

</div>
</form> 
</body>
</html>

Finally write this code in code behind of aspx page to update record

protected void GridView1_RowUpdating
(object sender, GridViewUpdateEventArgs e)
{
//Find dropdown to get selected Item text  
DropDownList ddlGridCountry = (DropDownList)
GridView1.Rows[e.RowIndex].FindControl("ddlCountry");
string strCountry =
ddlGridCountry.SelectedItem.Text.ToString();

DropDownList ddlGridCity = (DropDownList)
GridView1.Rows[e.RowIndex].FindControl("ddlCity");
string strCity =
ddlGridCity.SelectedItem.Text.ToString();

SqlDataSource1.UpdateParameters.Clear();
SqlDataSource1.UpdateParameters.Add
("Country", strCountry);
SqlDataSource1.UpdateParameters.Add("City", strCity);
}

Hope this helps
