I am not sure how much those libraries can be integrated with .Net; some are Java orientated

http://developer.yahoo.com/yui/ The YUI Library is a set of utilities and controls, written in JavaScript, for building richly interactive web applications using techniques such as DOM scripting, DHTML and AJAX. YUI is available under a BSD license and is free for all uses. The YUI project includes the YUI Library and two build-time tools: YUI Compressor (minification) and YUI Doc (documentation engine for JavaScript code).

projects to look at:

http://sourceforge.net/projects/magicajax A framework that provides AJAX technologies for web pages created with ASP.NET. It allows developers to easily integrate AJAX support into their pages without replacing the ASP.NET controls and/or writing javascript code.
http://anthem-dot-net.sourceforge.net/ The Anthem project adds AJAX-like features to ASP.NET. What sets Anthem apart from other frameworks is that it integrates itself into the server-side control model made popular by ASP.NET. This includes full support for view state, server-side events, and everything else the typical ASP.NET developer has grown accustomed to.

http://gaiaware.net/ Gaia Ajax is an Open Source RAD Ajax Framework for ASP.NET that eases the development of dynamic web applications. Gaia abstracts away JavaScript and allows you to write everything in .NET managed code like C# and VB.NET.
