2/11/2015 - By Pranav Singh 3

This article will show you how you Display Grand Total In Gridview Footer On RowDataBound in Asp.Net Using C#.Net. In this we will display to bind value total at run time in asp.net using c#.net.


So for this article first we will create a new asp.net application and add the below code in the page.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication1.WebForm1" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Display Grand Total In Gridview Footer On RowDataBound In Asp.Net Using C#.Net
    </title>
</head>
<body>
    <form id="form1" runat="server">
    <table width="100%" cellpadding="4" cellspacing="4">
        <tr>
            <td align="left">
                <asp:GridView ID="GridView1" runat="server" Width="100%"
                    AutoGenerateColumns="False"
                    ShowFooter="True" onrowdatabound="GridView1_RowDataBound">
                    <Columns>
                        <asp:TemplateField>
                            <HeaderTemplate>
                                 Name
                            </HeaderTemplate>
                            <ItemTemplate>
                                <asp:Label ID="lblName" runat="server" Text='<%# Eval("Name") %>'></asp:Label>
                            </ItemTemplate>
                            <FooterStyle Font-Bold="True" />
                        </asp:TemplateField>
                        <asp:TemplateField>
                            <HeaderTemplate>
                                 Address
                            </HeaderTemplate>
                            <ItemTemplate>
                                <asp:Label ID="lblNamAddress" runat="server" Text='<%# Eval("Address") %>'></asp:Label>
                            </ItemTemplate>
                        </asp:TemplateField>
                        <asp:TemplateField>
                            <HeaderTemplate>
                                 Type
                            </HeaderTemplate>
                            <FooterTemplate>
                               <b> Total :</b>
                            </FooterTemplate>
                            <ItemTemplate>
                                <asp:Label ID="lblUserType" runat="server" Text='<%# Eval("UserType") %>'></asp:Label>
                            </ItemTemplate>
                            <FooterStyle HorizontalAlign="Right" />
                        </asp:TemplateField>
                        <asp:TemplateField HeaderText="Earning">
                            <FooterTemplate>
                                 <asp:Label ID="lblGrandtotal" runat="server" Text='' Font-Bold="true"></asp:Label>
                            </FooterTemplate>
                            <ItemTemplate>
                                  <asp:Label ID="lbltotal" runat="server" Text='<%# Eval("Earning") %>'></asp:Label>
                            </ItemTemplate>
                        </asp:TemplateField>
                    </Columns>
                </asp:GridView>
            </td>
        </tr>
    </table>
    </form>
</body>
</html>

In above code I have use itemtemplate to bind the gridview fields and used label control to display the value using Eval. In HeaderTemplate I have added label control . I will detect this control and assign

Now check the footer of the gridview  in this I have added a label control in this I will display the total.

Now check the code to bind and display no of pages.

using System;
using System.Data.SqlClient;
using System.Data;
using System.Linq;
using System.Web.UI.WebControls;
using System.Collections;
namespace WebApplication1
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        DataTable objdt = new DataTable();
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                GetDistinctValue();
            }
        }
        private void GetDistinctValue()
        {
            SqlConnection con = new SqlConnection(System.Configuration.
ConfigurationManager.ConnectionStrings["con"].ToString());
            try
            {

                string query = "select * from UserDetail;";
                SqlDataAdapter da = new SqlDataAdapter(query, con);
                con.Open();
                da.Fill(objdt);
                con.Close();
                if (objdt.Rows.Count > 0)
                {
                    GridView1.DataSource = objdt;
                    GridView1.DataBind();
                }
            }
            catch
            {
                con.Close();
            }
        }

        protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.Footer)
            {
                var total = objdt.AsEnumerable().Select(c => new { earning = c.Field<int>("Earning") }).Sum(m => m.earning);
                Label lblTotal = (Label)e.Row.FindControl("lblGrandtotal");
                lblTotal.Text = total.ToString();
            }
        }
    }
}

On above code I have used a function to bind the data. Now I have I have added the control in footer to display the total. Now check the below code to display total value at run time.

                protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.Footer)
            {
                var total = objdt.AsEnumerable().Select(c => new { earning = c.Field<int>("Earning") }).Sum(m => m.earning);
                Label lblTotal = (Label)e.Row.FindControl("lblGrandtotal");
                lblTotal.Text = total.ToString();
            }
        }

In above code I have validated when the footer row is appearing.  After that I have get sum all values by using linq query, and then detected the label control to display the total.

Now we have done run the application to check the output.
