    Hi:

    If I add an Icon property to a RadRibbonBackstageItem, thus:

    <telerik:RadRibbonBackstageItem Header="Open View" IsDefault="True" Icon="/AttnHistory;component/Images/Ribbon/page_go.png">
        <StackPanel Margin="15 15 0 0">
            <TextBlock Text="Stored Views" FontSize="14" FontWeight="Bold" Margin="0 0 0 2" />
            <Rectangle Height="1" Fill="{StaticResource DottedLineBrush}" />
            <ItemsControl ItemsSource="{Binding StoredViews}" Margin="0 4 0 0" ItemTemplate="{StaticResource StoredViewTemplate}"/>
        </StackPanel>
    </telerik:RadRibbonBackstageItem>

    the BackstageItem element is underlined in the VS2010 XAML designer and shows an error. The associated error text is "[Line: 0 Position: 0]". The module compiles correctly, it runs correctly, and the icon is shown correctly. But working with the module in the designer is a pain in the butter. It also occasionally crashes the designer with:

    System.Reflection.TargetException
    Object does not match target type.
       at System.Reflection.RuntimeMethodInfo.CheckConsistency(Object target)
       at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks)

       at MS.Internal.Designer.VSDesignerClient.RestoreSelection(List`1 offsetsInXamlFile)
       at MS.Internal.Designer.DesignerPane.LoadDesignerView(Boolean isReload)

    Any ideas why this occurs, and is there a workaround, perhaps?

    By the way, I have other Backstage items with icons that work perfectly and don't exhibit the error, such as:

    <telerik:RadRibbonBackstageItem Header="New View" Command="{Binding NewButton}" IsSelectable="False" Icon="/AttnHistory;component/Images/Ribbon/page_add.png"/>

    Thank you,

    Hi Kelly,

    Could you please try your project with the latest binaries from Q3 release and tell me if the error still occurs?
