Three common mistake while creating application with ajax

I have found a great article about developing a application with ajax enabled rich text website.

Here is the three mistakes we are making..

Page events still fire during partial postbacks.

UpdatePanel events fire, even when not updating.

Control event handlers fire after Load events

Dave has posted a very good article on above mistake.

Here is the link for that..
