AJAX Control Toolkit

A free-to-use collection of UI Widgets for ASP.NET 4.x Projects

If you maintain projects that rely on early versions of ASP.NET, odds are you familiar with the open-source AJAX Control Toolkit. The library, first introduced and made popular by Microsoft, was brought over to our web development team here at DevExpress. We took on this responsibility, cleaned up the codebase, introduced improved Visual Studio support, and fixed nearly 900 issues.

We at DevExpress are happy to have helped web developers worldwide by making their library of choice more dependable and their development more straightforward.

Thanks to DevExpress I have been able to significantly improve my clients applications. Since turning to DevExpress from a competitor I have been easily able to upgrade my clients systems, and provide features that were previously virtually impossible. With the 90-odd controls available in ASP.NET as well as theming I am now able to create the kind of systems that are beautiful as well as functional.

Thanks DevExpress for your great product and the excellent support you have given me thus far!
