AJAX Control Toolkit (maintained by DevExpress)

Build status Installer

The ASP.NET AJAX Control Toolkit contains a rich set of controls that you can use to build highly responsive and interactive AJAX-enabled Web applications. AjaxControlToolkit contains more than 40 controls, including the AutoComplete, CollapsiblePanel, ColorPicker, MaskedEdit, Calendar, Accordion, and Watermark controls. Using AjaxControlToolkit, you can build AJAX-enabled ASP.NET Web Forms applications by dragging-and-dropping Toolkit controls from the Visual Studio Toolbox onto a Web Forms page.

v19.1.0 is now available! Get the new installer from


If you've used the toolkit in the past, you also know that for quite some time, the project was poorly supported, with an ever growing list of critical issues. Seeing the demand for such a library and considering its current state, we approached Microsoft and suggested that we help bring the Toolkit back into a dependable and usable state. Needless to say, Microsoft agreed. The good news is that since we took on this responsibility, we've managed to clean up the codebase, introduced improved Visual Studio support, and fixed nearly 900 bugs.
