Introduction

ASP.NET 2.0 AJAX Extensions enable you to enhance the capabilities of an ASP.NET Web application in order to create a rich user experience by combining JavaScript, DHTML and AJAX capabilities of the Web browser to include visual effects, client processing such as validation, and so on.

In this article. we will explore how to create an ASP.NET Web server control that extends an existing Web server control and uses features of Microsoft ASP.NET 2.0 AJAX Extensions to expand functionality in the browser. We can add functionality to client Document Object Model (DOM) elements by using a client control. We will see how the client control can be associated with a server control by implementing the IScriptControl interface in the new custom Web server control.
