You still have the earlier question in this page itself. It would been easier for people to understand the background too.

The Session_End event cannnot be handled when the browser is closed.

Some people suggest to handle onbeforeunload javascript event.

But it is not advisable because you cannot differenciate between a postback and browser close(clicking X button).

Also the link button will trigger this event twice.

You don't need to thing about it. It will close automatically when the session is time out !!

The exception clearly says that you are violating primary key constraint.

A simple way is to put try catch statement aroung your table inserting code.

Then handle SqlException and check the value of the Number property of the SqlException object if it equals to 2627.

try
 {
  //your db insert code goes here

 }
catch(SqlException ex)
 {
   
    if (ex.Number.Equals(2627))   
    {
       // Display your error here
    }
}

You need to check if the record exists for the primary key.
Only do a insert if the record does not exist. In other case, update the existing information (if it suits your application needs)

Is it possible to post a msg to the user using a label stating that the record already exists..

Yes, First you could check whether the Record exists using Primary Key Field,if exist then display the msg in label,if not add it.

Have a look at the global.asax file. There should be a method named "void Session_End(object sender, EventArgs e)". That's the one called by the engine whenever a session is closing/ends.

It's not a bug, it's a feature!

Check out my CodeProject article Permission-by-aspect.
