always check if the sessional value exist or not, see the solution i posted,

yup! +5

Solution 3

C#

if (!session["UserID"]==null && !session["UserName"]==null) 
{
   labelID.text= (string) Session["UserID"];
   labelUserName.text= (string) Session["UserName"];
}
else
{
   Response.Redirect("~/login.aspx");
}

using this, you are checking if user id and the user name are present in session if so then displaying the info on labels, if any of them doesnt exist, redirecting them to login.aspx.

in your log out code, dont rewrite the value of the sessional variables, instead drop them, use

C#

Session.Clear();

to clear all the sessional values.

Here are two links to get the full understadning of these oncepts related to it:

Understanding ASP.NET Roles and Membership - A Beginner's Tutorial[^]
Understanding and Implementing ASP.NET Custom Forms Authentication[^]

If you need a quick way of doing it then here is a project doing the same stuff. you can find some quick-to-use code here:
YaBlogEngine - A Tiny Blog Engine written in ASP.NET/C#[^]

code like:

C#

protected void Page_Load(object sender, EventArgs e)
      {
          if (Session["UserId"] == null)
          {
              Response.Redirect("Login.aspx");
          }
      }
