Ajax has certainly been a topic of discussion among web developers since XMLHttpRequest object was introduced. Since then numerous ajax wrappers for .Net has emerged like ajax.net by Michael Schwarz, atlas and others. But recently I bumped into Anthem.Net by Jason Diamond and I can't argue how simple the implementation with this is. For those of you who are looking to implement ajax in .Net check out Anthem.Net, which is a set of common .net controls with ajax capability. Versions for VS 2003 and 2005 are both available for download from source forge.
