Hi,

Would like to know simple examples on Session & application variable in asp.net.
I have created 3 pages, I am navigating from a to b, b to c, & again c to a. I would like to have the session counter to increase by 1. When i return back on pag e 'a'. But the session counter is increasing by 2 instead of 1.

Kindly suggest the desired output.

Thanks in advance..

Here's a quick fix for that.

First, create a class that will handle your SessionCounter;
C#
public class SessionCounter {
   public SessionCounter() {
      Counter = 1;
      LastPage = "A";
   }

   public int Counter { get; set; }
   public string LastPage { get; set; }
}



Then on your webpage insert this on your Page_Load

C#
protected void Page_Load(object sender, EventArgs e) {
            if (!IsPostBack) {
                SessionCounter sc = new SessionCounter();

                if (Session["SessionCounter"] != null) {
                    sc = (SessionCounter)Session["SessionCounter"];

                    //put your page letter here as the last page to trigger the increment 
                    //In your case, its page C
                    if (sc.LastPage == "C") {
                        sc.Counter++;
                    }

                    //put your page letter here (sample is for page A)
                    //update this per page
                    sc.LastPage = "A";
                }

                Session["SessionCounter"] = sc;
            }
        }


Good luck!
