Running Total In Gridview Footer In ASP.NET C# VB.NET

In this example i am going to demonstrate how to Display Running Total In GridView Footer Row In ASP.NET using C# and VB.NET. This method works with paging enabled gridview as well.

Running Total In Gridview Footer In ASP.NET

For demo purpose gridview is populated using sqldatasource having table with columns ID ,Name,Amount

I m showing total of amount column is gridview footer. for this we need to sum the the column in RowDataBound Even of Gridiew

Html source of gridview is
<asp:GridView ID="GridView1" runat="server" 
              DataKeyNames="ID" DataSourceID="SqlDataSource1" 
              ShowFooter="True" AllowPaging="True" PageSize="5" 
              BackColor="#ffffff" BorderColor="AliceBlue" 
              BorderStyle="None" BorderWidth="1px" 
              CellSpacing="2" FooterStyle-BackColor="#da821e" 
     <asp:BoundField DataField="ID" HeaderText="ID" 
                     InsertVisible="False" ReadOnly="True"
                     SortExpression="ID" />
     <asp:BoundField DataField="Name" HeaderText="Name" 
                     InsertVisible="False" ReadOnly="True"
                     SortExpression="Name" FooterText="Total"/>
     <asp:TemplateField HeaderText="Amount">
     <asp:Label ID="lblAmount" runat="server" 
                Text='<%# "$"+Eval("Amount").ToString()%>'>
     <asp:Label ID="lblTotal" runat="server"></asp:Label>
     <PagerStyle ForeColor="#8C4510" HorizontalAlign="Center" />
     <HeaderStyle BackColor="#da821e" Font-Bold="True" 
                  ForeColor="White" />
<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT [ID], [Name], [Amount] FROM [Expenses]">
Now we need to write code for summing the column in RowdataBound Even of GridView

C# code behind
public partial class _Default : System.Web.UI.Page 
    decimal grdTotal = 0;
    protected void Page_Load(object sender, EventArgs e)

protected void GridView1_RowDataBound
                   (object sender, GridViewRowEventArgs e)
 if (e.Row.RowType == DataControlRowType.DataRow)
  decimal rowTotal = Convert.ToDecimal
              (DataBinder.Eval(e.Row.DataItem, "Amount"));
  grdTotal = grdTotal + rowTotal;
 if (e.Row.RowType == DataControlRowType.Footer)
  Label lbl = (Label)e.Row.FindControl("lblTotal");
  lbl.Text = grdTotal.ToString("c");

VB.NET code behind
Public Partial Class _Default
    Inherits System.Web.UI.Page
    Private grdTotal As Decimal = 0
    Protected Sub Page_Load
    (ByVal sender As Object, ByVal e As EventArgs)
End Sub

Protected Sub GridView1_RowDataBound
(ByVal sender As Object, ByVal e As GridViewRowEventArgs)

If e.Row.RowType = DataControlRowType.DataRow Then
Dim rowTotal As Decimal = 
Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "Amount"))
grdTotal = grdTotal + rowTotal
End If

If e.Row.RowType = DataControlRowType.Footer Then
Dim lbl As Label = DirectCast(e.Row.FindControl
                           ("lblTotal"), Label)
lbl.Text = grdTotal.ToString("c")
End If
End Sub
End Class

Hope this helps

This will not work for a paged gridview with more rows than the maximum per page. It can only show the total for the page. However, if the accumulator variable is only zeroed out in the
!Page.IsPostBack then the totals can accumulate but only based on the pages selected so any value could be created for the total depending on the pages selected. Therefore, there is no way to get a running total in a paged gridview.

Plz look for code mentioned bolow in html source of gridview.

Text='<%# "$"+Eval("Amount").ToString()%>'

Now change the $ sign to whatever you like.

@Sunder: Have you written grdTotal = grdTotal + rowTotal; in rowDataBound And convert it to decimal ?

decimal rowTotal = Convert.ToDecimal
(DataBinder.Eval(e.Row.DataItem, "Amount"));

Your values are not converted to decimal so are getting append because of string type

Thank you very much for the code

I get no errors, which is fabulous, because all of the other examples I have found create pages and pages of errors. Sadly, I do not get a Total Either.

The GridView:
As above in example.

The Code Behind it:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
using System.Data.SqlClient;

namespace AudioNET
public partial class DemoInvStockVal : System.Web.UI.Page
decimal grdTotal = 0;
protected void Page_Load(object sender, EventArgs e)
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
if (e.Row.RowType == DataControlRowType.DataRow)
decimal rowTotal = Convert.ToDecimal
(DataBinder.Eval(e.Row.DataItem, "VALUE"));
grdTotal = grdTotal + rowTotal;
if (e.Row.RowType == DataControlRowType.Footer)
Label lbl = (Label)e.Row.FindControl("lblTotal");
lbl.Text = grdTotal.ToString("c");
