The following code for Raising the Event, when we close a page on a browser. Just create a temp page for updating the values to Database. For example if we have a normal page as sample.aspx. But we need the affect the Database while we close that page. For that we create a Dummy page as Default.aspx. In that page write the code for database updation. Just raise the event of "onbeforeunload" in main page(sample.aspx), for that event we call handleonclose() function in javascript. In that script we calling the dummy page(default.aspx). Then we can update the Database easily. But only one problem is whenever you refreshes the page, the event will fired. This may be used in POP UP windows.
