I am not sure exactly what you are trying to do, but here are some problems I see with the snippet you sent:

1) take the RadAjaxManager out of the update panel, it is a control that creates update panels

2) open the RadWindow from the code-behind as suggested in the sticky thread at the top of the section: http://www.telerik.com/community/forums/aspnet-ajax/window/opening-radwindow-from-the-server.aspx.

3) take the RadWindow out of the update panel and the panel updated by the RadAjaxManager. If you need AJAX inside its ContentTemplate - this article will tell you how to do it: http://www.telerik.com/help/aspnet-ajax/window-ajaxifying.html.
