The article shows how you can add AJAX capabilities into a new or existing website by using a new ASP.NET AJAX server-side control called the UpdatePanel. UpdatePanel control is used to allow portions of a page to be updated without requiring the entire page to be posted back to the server and reloaded in the broser. The article goes on explaining some other important ASP.NET AJAX extensions. The article is a bit advanced and more technical, so I won’t go into more details.
I know we didn’t learn much about AJAX but since we learned about ASP.NET, I thought this article was important. This would be much helpful if we were developing big scale web applications with ASP.NET.
