When you post to another page in ASP.NET 2.0, you can reach out to the values in the page using the following methods:


using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class _Default : System.Web.UI.Page
    protected void Page_Load(object sender, EventArgs e)
    protected void Button1_Click(object sender, EventArgs e)
        if (PreviousPage != null)
            TextBox txtName = (TextBox)
            this.TxtName.Text= txtName.Text;
