I sent you the .wsp file via mail. The automatic Sharepoint installation will add SafeControl entries and deployment actions for the SPRadGrid and SPRadEditor assemblies. To register the regular RadControls for ASP.NET AJAX suite, you need to follow these steps
The Telerik Silverlight controls web part wrappers should work with Sharepoint Foundation although they do not provide automated installer or ready-to-deploy Sharepoint 2010 web parts. Hence you will need to register them manually.
We will also appreciate if you share with us your feedback concerning the features we delivered for the AJAX editor and grid webparts built for SharePoint 2010. Additionally, we are interested to have your opinion on what additional features/other webparts you would like to see for the next versions of our SharePoint 2010 offering.
