Book: Professional ASP.NET 2.0 AJAX Released
Matt Gibbs and I recently released a new book for WROX titled Professional ASP.NET 2.0 AJAX that covers all the topics you need to know to build robust ASP.NET AJAX applications. Matt is a development manager for ASP.NET (and led the ASP.NET AJAX team) and I've had the opportunity to be involved with the product since the early alphas. We put a lot of work into the book so hopefully everyone finds it useful and educational....don't let the cover scare you away. :-)

Video: Working with ASP.NET AJAX UpdatePanel Properties
This video tutorial demonstrates the affect the UpdatePanel's UpdateMode and ChildrenAsTriggers properties have on updating a panel's content. The video starts out by discussing the UpdateMode property and shows why you may want to know about it when using multiple UpdatePanel controls on a single page. It then discusses the ChildrenAsTriggers property and shows how you can prevent child controls from updating their parent UpdatePanel control. Examples of nesting UpdatePanel controls to provide a master-details style view of data is also shown.

AJAX Hacker Attacks - Cross Site Request Forgery
I was reading an article that was posted yesterday about various AJAX security vulnerabilities that was pretty interesting. It documents how many AJAX frameworks allow GET requests to hi-jack JSON messages and process them as desired. This is a big deal since any sensitive information included within a JSON message would be viewable to a clever CSRF (Cross Site Request Forgery) hacker.
Microsoft's Scott Guthrie cleared up the issue with regard to the ASP.NET AJAX framework today. He wrote up a great post describing how the framework automatically disables GET requests by default (the UpdatePanel uses POST operations) and they add a special application/json content type header that is checked. The architects of the ASP.NET AJAX framework did a great job thinking this through and ensuring that the framework prevented these types of attacks "out of the box". -
