A Comparison of Ajax Frameworks for ASP.NET: “As highlighted in this post on the Ajax.NET Professional blog today, there’s a comparison posted of several of the popular Ajax frameworks for those working with ASP.NET (created by Daniel Zeiss). First, let me explain why only these 6 Frameworks are included although there is a lot more AJAX stuff for ASP.NET out there. All the frameworks listed here have one unique AJAX feature: They allow updating page content without programming AJAX directly – i call it indirect AJAX programming – a compareable concept is called Hijax. Therefore, frameworks that supply only controls with built in AJAX-features (Trees, Grids, Lists and so on…) are not included in the comparison. Please forgive me and drop me a note if I forgot a framework that also allows indirect AJAX programming. The list for the comparison includes: ComfortASP.NET V0.45 (beta) MagicAJAX.NET V0.2.2 ComponentArt V3.0 Callback Control and more… He has very detailed charts covering different topics like general information about the package, it’s ASP.NET compatibility, how much “traffic” it generates with its requests, and other additional features. There’s even charts for the traffic (in bytes) for a few different tests he performs with each package. “
