Gaia Ajax Web Widgets is an Open Source Ajax library for developing Ajax applications for ASP.NET. (2.0 and higher) It is a commercial library, but has a GPL version for developing Free Software with. It has a different approach than most of the other Ajax widgets libraries that mostly update the complete HTML and sends HTML over the net. Instead Gaia has chosen to mirror the control class hierarchy on the client side and post JavaScript updates to concrete objects. It relies heavily on Prototype.js and Scriptaculous in its core and consists of fairly advanced JavaScript code like prototype inheritance and JavaScript "polymorphism". Like Google Web Toolkit, JavaScript is abstracted away, so the developer can develop in the .NET language of choice without knowledge of JavaScript.
