Disable a parent page when a RadWindow opens

Question

When i open a Radwindow i would like the parent page to be disabled. The user shoudn't be able to do anything on this page if the radWindow is open.

<telerik:RadWindowManager ID="RadWindowManager1" runat="server" EnableShadow="true">
    <Windows>
        <telerik:RadWindow ID="RadWindow1" runat="server" Width="550px" Height="570px" Title="Nouveau ticket"
            Skin="Windows7" Behaviors="Close, Move" >
        </telerik:RadWindow>
    </Windows>
</telerik:RadWindowManager>

This is the code i'm using. I hope you see what i'm looking for. Thanks for your help.

RadWindow has a property "Modal". Set Modal="True" on the control to disable the parent page.
