Take a look here: http://demos.telerik.com/aspnet-ajax/controls/examples/integration/gridandwindow/defaultcs.aspx?product=window . This demo from Telerik shows how you can use the OnClientClose event of the RadWindow control to trigger a partial postback that will update the grid. Please note: most of the code is on the main page where the grid is, and not on the content page loaded in RadWindow.

This approach to opening RadWindow from code is better if you cannot use the client logic from the demo: http://www.telerik.com/community/forums/aspnet-ajax/window/opening-radwindow-from-the-server.aspx .
