In their ASP.NET AJAX Q2 Beta release, Telerik packaged RadEditor and RadGrid as standalone web parts for Sharepoint 2010.
“Need to use our AJAX controls in a custom Sharepoint 2007/2010 implementation? Not a problem at all. RadEditor, RadGrid and the rest of our ASP.NET AJAX components can also be plugged very easily into Sharepoint 2007/2010 visual/dynamic web parts, or placed directly into Sharepoint pages/user controls.”
