find a client Side event of radGrid or Div that occur before any postback

[Reza]

hi friends,

i have a radgrid in my page that some script have set for OnGridDestroying event. my script get all controls and their value in page and sent them with Ajax to server side with a httprequest object . consider a button on page too that cause a postback, but i want to process my request object before any post back in page . i tryed window.onbeforeunload , it works fine till i use radajaxpanel or a update panel on page... is there any javascript event that fire before any post back that i can set for my radGrid or its parent that is a div element?

thanks

Hello,

You could try to use the OnClientClick event of the button or the initializeRequest event of the PageRequestManager.

The initializeRequest is fired just before the request has been initialized and thus is should suite your needs.

All the best,
