[How Do I:] Determine Whether an Asynchronous Postback has Occurred?

Please install Silverlight or click download to watch video locally.

The Page_Load method of an ASP.NET Web form will execute during either a standard full-page postback or an asychnronous partial-page postback. In this video we learn how we can use the ASP.NET AJAX ScriptManager to determine whether an UpdatePanel postback has occurred, which allows us to conditionally execute code.

Good tutorial Joe. Thanks for this videos.

If you had multiple updatePanel, how would know which one has been update.( Can you map from ScriptManager1 to UpdatePanel1 or UpdatePanel2.)
