window close event

Hi,

In my web application, I need to do certain things like clearing the session when the user clicks on close button in browser.

Is there any event. dont tell me unload event, because this will be triggered each time of post back. I want a event that will be triggered only when user clicks on close button?

Also, can we prevent the same form to be opened twice?

Thanks in Advance

Re: window close event

Off hand I think you would have to write an event to capture the close button being pushed, then inside there you could do Session.Clear().

Not quite sure about this one......are you talking about the X close button OR your own custom button?

Re: window close event

why not handling that in your global.asax session_end event where you can clear out your session.

Re: window close event

I believe you have 2 write client side code for the window.onbeforeunload event. But I don't know what to exactly write in there...

EDIT: I mean you have to write code to call some server side function which call a Session.Clear or the like, but I don't know how to write so...

Hi Shobana P.S ,

You can open a new page when user close a page window.

Then you can clear the session, and close the window, do't send html to user.

Let me know if I have misunderstood what you mean.
Thanks.
Hope it helps,
