If you've been a subscriber of my blog for while, you probably know that I am a big fan of ComponentArt's Web.UI controls.  Their controls are absolutely outstanding, both from a user's and a developers perspective.

ComponentArt has announced a new suite of controls created specifically for Microsoft's ASP.NET AJAX framework (formerly known as Atlas).  With extensive client-side APIs, integration with the Atlas type system, and optimized to work with the UpdatePanel control, this suite should prove to be the premier components for building rich, interactive AJAX-enabled Web applications.
