ModalBackground isn't working

[Aaron]

WPF RadWindow (Q1 2010) is never showing a modal background.

Here is simple example xaml:

Window x:Class="Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:telerikNavigation="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation"
        Title="Window1" Height="400" Width="600" WindowStartupLocation="CenterOwner">
    <Grid>
        <telerikNavigation:RadWindow ModalBackground="Red"
                           Name="testObj" Height="100" Width="200" CanClose="True"
                          WindowStartupLocation="CenterOwner" Background="Beige"/>
    </Grid>
</Window>

Here is the code:

Class Window1
    Public Sub x() Handles Me.MouseLeftButtonDown
        testObj.ShowDialog()
    End Sub
End Class

Image is attached.

Any idea what's up?

Thanks

Is there another property that I should be using?  Or is a modal background not supported by this RadWindow at all?

Hi Aaron,

RadWindow for WPF does not support modal background except when it is in XBAP mode.

Sorry for the caused inconvenience once again.
