Ajax Control Toolkit

ASP.NET AJAX Control Toolkit

Welcome to the ASP.NET AJAX Control Toolkit.


Choose from any of the samples on the left to see the live controls in action, and experiment with their different possibilities.

What is the ASP.NET AJAX Control Toolkit?

The ASP.NET AJAX Control Toolkit is an open-source project built on top of the Microsoft ASP.NET AJAX framework. It is a joint effort between Microsoft and the ASP.NET AJAX community that provides a powerful infrastructure to write reusable, customizable and extensible ASP.NET AJAX extenders and controls, as well as a rich array of controls that can be used out of the box to create an interactive Web experience.


The AJAX Control Toolkit contains more than 30 controls that enable you to easily create rich, interactive web pages.


To get started, and to install the Ajax Control Toolkit, visit the AJAX Control Toolkit Project Page on CodePlex.


To learn more, read the Getting Started Tutorial, or the other walkthroughs, tutorials and videos shown on the left.
