0	window.event doesnt work with browsers other than IE. So it is always better to hook into events that are supported to all the browsers : window.onbeforeunload = function () { } This is called everytime when the window is getting closed in most of the browsers. See my reply here : http://www.codeproject.com/tips/41771/How-to-detect-browser-close-when-browser-X-is-clic.aspx Also you need to tactfully handle this event, as it will be called everytime you navigate away from the page. I hope this will help you. Cheers. www.abhisheksur.com Bhavna81, if this helps please login to Mark As Answer. \| Alert Moderator

0	You can try the following code. <html> <body onUnLoad=' whatever function''> </html> Bur remember one thing onUnLoad will be called even if the page is posted back. So you have to handle that too in the Javascript code. Mark this as answer, if it is..... With regards Nishithraj Narayanan Bhavna81, if this helps please login to Mark As Answer. \| Alert Moderator
