I have a website using .NET 2.0 and I've been using RadControls for ASP.NET very successfully.  I'm wanting to try out the new AJAX release of the controls but I'm having difficulty installing them onto the site. I'm using VWDe 2008 and I've tryed the following on 2 different machines.

Download and install RadControls for ASP.NET AJAX
Open Website using VWDe 2008
Open Toolbox -> Choose items -> browse
Select -> Program Files/telerik/Rad Controls for ASPNET Ajax Q2 2008/bin/telerik.web.ui.dll

and I get the following ERROR message
"
There was an error loading types from assembly 'C:\program Files\Telerik\RadControls for ASPNET AJAX Q2 2008\Bin\Telerik.Web.UI.dll'
'Could not load file or assembly 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral,
PublickKeyToken=31bf3856ad364e35' or one of it's dependencies. The system
cannot find the file specified.'
"

I'd prefer to keep my website on .NET 2.0 and try using the new controls.  Please help.

Hello ssjones,

You can definitely still use our controls with version 2.0 of the .NET framework. It looks like the error you are getting is due to the fact that the ASP.NET AJAX extensions are not found on your computer. Unlike the latest version of the .NET framework, these extensions do not come built-in. However, you can download them here and install them manually. Try installing them and if you continue to have trouble, please let me know.

Regards,
Kevin Babcock

I have also problems with asp.net 2.0:

The components draw like standard .net component's not like radcontrols, and the components don't work!

I am using Windows Vista, Visual Studio 2008, asp.net 2.0 plus the AJAX Extensions. The JS-error I got is something like: "Sys is not defined".

Andreas,

I don't know whether you have the extensions or not. The error you shared means that System.Web.Extensions can't be found. Try to add reference to the assembly and make sure your project (website/webapplication) is AJAX-enabled.

How to: Add or Remove References in Visual Studio
Google - "Could not load file or assembly 'System.Web.Extensions" - 10,000 results

Hope this helps
