In the inline code

<script language="javascript" type="text/javascript">
window.onbeforeunload = WindowCloseHanlder;
    function WindowCloseHanlder()
        {
           alert("ur closing broswer");
         
            PageMethods.AbandonSession();
        }
</script> 

 <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true">

In the code behind(class file)

 [WebMethod]
        public static void AbandonSession()
        {
            HttpContext.Current.Session.Abandon();
            HttpContext.Current.Application.RemoveAll();
        }

But its work in IE Browser not in Mozilla and chrome

Solution 1

Here is a code that works in Chrome & Mozilla.

window.onbeforeunload = function(e){
    var msg = 'Are you sure you want to close?';
    e = e || window.event;

    if(e)
        e.returnValue = msg;

    return msg;
}

Hope this helps!
Cheers
