Suppose a web page called CollectData.aspx contains a TextBox control called TextBox1 and a Button control that has its PostBackUrl set to “~/ProcessingPage.aspx”. ProcessingPage.aspx is the second page that contains a Label control called Label1. Code for access the Textbox control data in ProcessingPage.aspx page is as follows.
Label1.Text = ((TextBox)PreviousPage.FindControl("TextBox1")).Text;
3. Client-Side Browser Redirect

Example:
Response.Redirect("NextPage.aspx");
