Updatepanelanimationextender on updating

In this article, we will study three different techniques that allow you to visually display progress to users while performing partial-page updates using the Update Panel.

As shown in the code above, we first get a reference to the Page Request Manager and then wire up the initialize Request and end Request events to execute, when an async postback begins and ends respectively.

The button that caused the postback is disabled during this event, so in order to prevent users from hitting the button again.

Another very simple option to display progress during an async postback is to use the Update Progress control.
