Closing RadWindow from target url

This must be a stupid question, but I've been unable to find it.

I have an asp.net control that includes a RadWindowManager that has a child RadWindow. The RadWindow has the property NavigateUrl set to an asp.net page. I wish to have a Submit button that will do some server interaction and then close the RadWindow. The page that is the target of the NavigateUrl property doesn't have a reference to the window, which is the source of the problem.

Control

<asp:Conte开发者_开发知识库nt>
    <RadWindowManager>
        <RadWindow NavigateUrl="PageLocation">
    </RadWindowManager>
</asp:Content>

Page

<asp:Content>
    <telerik:RadButton Text="Submit" OnClick="CloseRadWindow"/>
</asp:Content>

How can I have a page with a button that can control the closing of its container (the RadWindow)?

Try using self.close(); at the point where you want to close the RadWindow:

<telerik:RadButton ID="Submit" OnClientClick="self.close();return false;" ... />
