Please advise.

In C# you can define a session variable like this:

Session["userame"]= txtusername.Text;

where txtusername is a text box. In another page you can call it as:

string usrname = Session["username"].ToString();

To check whether a user is logged in or not, in a particular page; you'll have to check if this session is empty or not. If the session is null then redirect the user to login page else he/she can view the page. Same logic applies to all the pages where you want to implement the session validation. Sample (on Page_Load event):

if (Session["username"] == null)
   Response.Redirect ("Login.aspx");

Hope it helps... :)
