May be you are using wrong version of the ControlToolkit!

Read this:
Setting up the environment to use the Toolkit: This Toolkit release targets two different versions of the .NET Framework:
Version 3.5.20229for .NET Framework 3.5 and Visual Studio 2008:
Download the AjaxControlToolkit-Framework3.5.zip orAjaxControlToolkit-Framework3.5-NoSource.zip.
Version 1.0.20229for ASP.NET AJAX version 1.0 and .NET Framework 2.0:
Download the AjaxControlToolkit.zip orAjaxControlToolkit-NoSource.zip.

The error means you din't registered AjaxControlToolKit assembly. Register the assembly after @Page directive. Try this:

HTML

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>

And also add a reference of AjaxControlToolkit ddl in your solution. (Right Click on solution explorer --> Add Reference --> Browse Tab --> Browse the file then click on OK)
