Name first page as WebForm1.aspx

<%@ 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">

<%-- webPage1--%>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:gridview runat="server"  ID="gridview1"
            AutoGenerateSelectButton="True" BorderStyle="Solid"
            onselectedindexchanged="gridview1_SelectedIndexChanged">
        </asp:gridview>
    </div>
    <asp:Button runat="server" Text="Next" onclick="Next_Click"/>
    </form>
</body>
</html>

The code file is as follow for your first page

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;

namespace WebApplication1
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            DataTable dt = new DataTable();
            dt.Columns.Add("Name");
            dt.Columns.Add("Surname");
            dt.Rows.Add("Rk", "Hirpara");
            dt.Rows.Add("Mark", "Twain");
            dt.Rows.Add("Imar", "Spaanjaar");
            dt.Rows.Add("Jerry", "Bank");
            dt.Rows.Add("Shreya", "Shah");
            gridview1.DataSource = dt;
            gridview1.DataBind();
        }

        protected void gridview1_SelectedIndexChanged(object sender, EventArgs e)
        {
            Session["Name"] = (gridview1.Rows[gridview1.SelectedIndex].Cells[1].Text);
        }

        protected void Next_Click(object sender, EventArgs e)
        {
            Response.Redirect("~/WebForm2.aspx");
        }
    }
}

Name first page as WebForm2.aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm2.aspx.cs" Inherits="WebApplication1.WebForm2" %>

<!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></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        Selected Name :
        <asp:TextBox ID="txtName" runat="server"></asp:TextBox>
    </div>
    </form>
</body>
</html>

The code for your second page is as follow

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace WebApplication1
{
    public partial class WebForm2 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            txtName.Text = Session["Name"] != null ? Session["Name"].ToString() : "";
        }
    }
}

// If this is not what u wanted then please clarify the problem definition in detail and if resolved then you have

more option to do this like using queryString, Cookie, or dataBase, ViewState.

Thanks and Regards,

Hi,

You need to find the row control of which butten is clicked and then you need to pass the value of all the controls using querystring to your webpage2.

on webpag2 using this querystring you can put values into the textbox.

or it will be like this

<asp:TemplateField HeaderText="Command">
                                    <ItemTemplate>
                                        <a href='webpage2.aspx.aspx?Id=<%# Eval("ProductId")%> &&ProductName=<%# Eval("ProductName")%>'>Send To webpage2</a>
                                       
                                    </ItemTemplate>
                                </asp:TemplateField>


//On webpage2 pageloadevent

textbox1.Text=Request.QueryString["Id"].ToString();
textbox2.Text=Request.QueryString["ProductName"].ToString();

Be the Best.........
