ASP.NET provides a few ways to move to different pages. In this post i try to show you how
you redirect from first page to second page.and how you get the value.

Step1:Open your project and take textbox and a button.
Step2: Type the code behind the button
protected void Button1_Click(object sender, EventArgs e)
    {
        Response.Redirect("SecondPage.aspx?Name=" + TextBox1.Text);
    }

Step3: Create a new aspweb page and name it SecondPage.aspx
Step4:Write down the code inside the pageload method
String sString;
        sString = Request.QueryString["Name"];
        Response.Write("Your name is " +sString);


Step5:Set FirstPageUI.aspx as your first page
Step6: Run the project. Give some value to the text field. Click on the button. You will see the result.
