Encosia has written a great article on common mistake developers make when using ASP.Net AJAX.

It’s important to remember that a partial postback is just that: A postback.

The UpdatePanel’s way of abstracting AJAX functionality behind standard WebForm methodology provides us with flexibility and familiarity. However, this also means that using an UpdatePanel requires careful attention to the ASP.NET Page Life Cycle.

In this post, I’d like to point out a few of the problems I’ve seen developers running into and what you can keep in mind to avoid them:

* Page events still fire during partial postbacks.
* UpdatePanel events fire, even when not updating.
* Control event handlers fire after Load events.
