download this ajax toolkit from given link: http://ajaxcontroltoolkit.codeplex.com/downloads/get/373744
add the ajaxtoolkit.dll from the folder to your already existing ajax menu by browsing and selecting appropriate folder where you have
downloaded ajax toolkit.

This means that you need to go into IIS and switch this website to using ASP.NET 4 instead of ASP.NET 2. If this is a hosted site, verify with your hosting provider that they support ASP.NET 4.
Check whether the AjaxControlToolkit is fit for the .NET version:
April 12, 2010 release of the AJAX Control Toolkit for ASP.NET 3.5 Service Pack 1 and Visual Studio 2008 SP1. In the download zip. Open the two folder of this path …\AjaxControlToolkit\AjaxControlToolkit.Source\Server\AjaxControlToolkit, Dll file in binary.NET4
is for .NET 4.0 Dll file in binary.NET35 is for .NET 3.5
