Anthem.Net - AJAX for ASP.NET

This group of controls are set up to use AJAX right "out of the box" and a really pretty easy to use. In fact, I have used them in just about every project I've done since I found it. It's really nice!

hi,
Are you try Ajaxium? Ajaxium is designed as an ultimate AJAX engine
for the entire ASP.NET pages including all standard,
custom and most of third-party ASP.NET controls.

In contrast to other AJAX-based approaches and huge AJAX
frameworks, Ajaxium-powered sites remain accessible to all
search engines and old browsers due to an automatic and silent
degradation to the classic ASP.NET.

Just had a look - rather expensive, especially as the new Microsoft offering is free!
