Abstract
By now, you are quite familiar with the ASP.NET AJAX server controls and have seen many examples of their use. The first release version of ASP.NET AJAX also shipped with a set of controls packed under the ASP.NET AJAX Toolkit moniker. These are open source control extensions that have been created by Microsoft as well as the broader community. This package is readily available at http://ajax.asp.net along with documentation and instructional videos. You can also obtain the latest source code at CodePlex (http://codeplex.com), Microsoft’s open source project depository. Either way, you have the option to download just the binaries or the full source code.
