Anthem.NET - a better AJAX for .NET applications
If you want to get started with AJAX for .NET and you are looking around for a platform you should give some consideration to a library I found called Anthem.NET. Its very easy to setup and works by simply changing the namespace of most of the standard asp controls to “anthem” and then telling the control to do a callback instead of a postback. Check out some samples. The Microsoft counterpart to this is called ASP.NET AJAX (Atlas) and in comparing the two I found the Anthem derived controls easier to use than the extenders or the UpdatePanel that atlas uses. Check it out.
