Hi all I am relatively new to ASP.NET and would appreciate a little help with a problem I am having. I have a "login" page that (upon validation of username/password) loads up another page. Now I have both these pages (I am using c# btw) written, however I cannot find the (probably one line of) code that I need to get the login screen to launch the second screen. Thanks for your time.

Sorry forgot to add code for login form

    void Button1_Click(Object Source, EventArgs E)
    {
        if(TextBox1.Text=="" && TextBox2.Text=="")
        {
            Label1.Text = "OK";
            
        }
        else
        {
            Label1.Text = "Invalid input";
        }
    }

you need a response.redirect to the correct page, or server.transfer. However, you should set a unique id in a session variable for the user. Then have a protection script to run on every page much like:

if (session["userid"] == "") { response.redirect("login.aspx") }
