Use ajax to call some server side method to record close event's time/date...

Follow Kornfeld Eliyahu Peter suggestion. You might want to place the clean up code in an OnFormClosed event handler.

You can do what Kornfeld suggested but there is no guarantee it will work. Trying to keep track of users that are currently logged in in ASP.Net is not a good idea.

In ASP.Net, it won't be guaranteed accurate. The web is a disconnected medium. They could force their browser closed through task manager and your code can't catch that. They could lose power and you can't catch that. Usually it's more work than it's worth.
