Hi,

I do this to set a variable:
private void Page_Load(object sender, System.EventArgs e)
            {
                  // Put user code to initialize the page here
                   string strVar =Request.ServerVariables["HTTP_REFERER"];
                  
            }
How do I retrieve this variable in ibtnSubmit_Click?

Define the variable before the page_load sub, you now can access it in all subs:

string strVar

private void Page_Load(object sender, System.EventArgs e)
          {
               // Put user code to initialize the page here
                string strVar =Request.ServerVariables["HTTP_REFERER"];
               
          }

I'm assuming these are not the same request, or else you could just pull from Request.ServerVariables in btnSubmit.

I'd add the property to viewstate (works just like the session, only it's page based), if you are accessing this across requests, proten's solution will not work.

Thanks raterus.

viewstate and session both worked.  

Session["myvar"] = Request.ServerVariables["HTTP_REFERER"];
