Some times we need to detect the Browser Close to perform some operation before quiting from application. Here is a simple way.

Call this Method From Body Unload



function CheckBrowser()

{

     // Check Browser Close [X] , Alt+F4 , File -> Close  

     if(window.event.clientX < 0 && window.event.clientY <0)

    {

          window.open("Operation.aspx", 

                "Operation",'left=12000,top=1200,width=10,height=1');

    }

}
