1) first time, I installed the ASP.NET AJAX RadControls, then also installed the SharePoint Acceleration Kit, but after I put RadTreeView control inside a web part project, i was getting error message saying "Telerik.Web.UI" could not be found when I tried to view a page hosting this web part-but I could see "Telerik.Web.UI" was clearly in the GAC
2) second attempt, after uninstalling both the Acceleration Kit and the ASP.Net AJAX RadControls, and removing Telerik related entries in the GAC, I only installed the SharePoint Acceleration Kit, and interestingly, nothing showed up in the Toolbox in VS2010!
3) third attempt, removed the Acceleration kit, I installed only the ASP.NET AJAX RadControls this time, and now I really cannot find "Telerik.Web.UI" in the GAC, I am only seeing "Telerik.Web.Design" in the GAC!
4) after manually registering the Telerik.Web.UI DLL into GAC, the issue remains, see the attached picture.

And the control I am interested here is the RADTreeView, I presume it is under Telerik.Web.UI, not Telerik.Web.Design? What am I missing?

Resolved these issue, what I did:
1) Only installing the RadControls AJAX,
2) Manually registered BOTH Telerik.Web.UI, Telerik.Web.Design assemblies into the GAC
3) Make sure the web.config is correct, especially put the Telerik.Web.UI.WebResource.axd entry in the  <handlers> instead of <httpHandlers>, and make sure for the <SafeControl> entries the version numbers for Telerik products are correct 
4) Last thing I did to ensure the RadTreeView control works inside a custom web part, is actually removing the ScriptManager from my custom web part, as the SharePoint 2010 page already included a ScriptManager.
