[Solved] SelectedIndex update SelectedItem in RadListBox in RadDropDownButton

[Shawn]

Hello,

I have a RadListBox in the DropDownContent of a RadDropDownButton like so:

<telerik:RadDropDownButton Grid.Row="1" Grid.Column="1" Margin="5">
    <telerik:RadDropDownButton.Content>
        <Viewbox>
        <TextBlock x:Name="uxtbDDBDisplay"/>
        </Viewbox>
    </telerik:RadDropDownButton.Content>
    <telerik:RadDropDownButton.DropDownContent>
        <telerik:RadListBox x:Name="uxlstOptions" MinWidth="85" MaxHeight="200" SelectionMode="Single"/>
    </telerik:RadDropDownButton.DropDownContent>
</telerik:RadDropDownButton>

The problem is when I update the SelectedIndex or SelectedItem on the RadListBox it does not update the opposite until the RadDropDownButton is opened.

Complete source of sample project here: http://dl.dropbox.com/u/22869986/RadDropdownTestProject.zip

Is there anyway to make this work without forcing the user to open the RadDropDownButton first?

Please note: this worked as expected before the most recent update.
