im using the radwindowmanager to show a dialog and when the dialog shows up, it sits behind a flash object on the calling page. in the dialog, there is a radtabstrip and this shows above the flash fine. i added the following with no luck:
<
telerik:RadWindowManager ID="RadWindowManager1" runat="server" Skin="Vista" Width="600px" Height="400px" CssClass="modal" Modal="true">
-- in my style sheet
.modal
{
z-index:7000;
}
