Most of you experts know about this problem.Please help get the correct solution.
I have List view, Ajax calendar extendars, Autocomplete extendars and Other asp server controls on a page.
i'm asking the user, if he really have to navigate away from the page , if he closes or navigates to other page, without saving data.
but On every postback(like List view Edit,Update,Insert activity), i get this message.
i have read about setting a variable on postback and checking it before unload of window.
I'm a novice and please help.
After onbeforeunload, can i call another page , which does some database calls???
