prompt user before exiting

Hi!
I have a asp.net form. I need to prompt user something like 'Are you sure you want to exit?' by using confirm. If the user clicks cancel button i need to stay on that form else i need to close the form. The unload event of window doesn't allow to cancel the event. Is there any work around to do it? Also i need to show the same message if the user goes to some other page from same browser. Any help will be greatly appreciated.

Thanking you

Regards

Hi Sandeep

you need to use the onbeforeunload event, which fires right before onunload. You can get the user to confirm, by simply setting event.returnValue to the text you want to use. So something like:
<BODY onbeforeunload="event.returnValue='Are you sure?'">

I could only get this to work in internet explorer tho.

Hope this helps
