Cancelling Async Postback in AJAX

About This Page:

This Demo is an extension of a previous Demo on Animating a GridView using UpdatePanelAnimationExtender control. There are times when an asynchronous update is taking place and we do not know if there is any progress being made. Professor Rasala had suggested that there should be some mechanism to either animate the update panel while the update was taking place or even cancel the updation of panel if the update is taking too long. In this demo I will allow a user to cancel an async postback in AJAX by using the cancel option. Clicking the cancel button will call a javascript Abort() method which will cancel async Postback.
