When using a diagram in the theme Windows8, the all the text in the RadComboBox controls inside SettingsPaneTextControl is not showing.

Please see the attached file for example.

In a newly created empty Silverlight project, the Theme is set to Windows 8:

StyleManager.ApplicationTheme = new Windows8Theme();

Create a RadDiagram in a xaml file

<telerik:RadDiagram x:Name="diagram">
            <telerik:RadDiagramTextShape Content="Test" />
            <primitives:ItemInformationAdorner.AdditionalContent>
                <telerik:SettingsPane Diagram="{Binding ElementName=diagram}" />
            </primitives:ItemInformationAdorner.AdditionalContent>
        </telerik:RadDiagram>

And the text in the RadComboBox controls inside SettingsPaneTextControl is not visible.

most other themes work fine, but Window8 is not.

I already updated to the latest Telerik Silverlight libraries.

 

 

This reproduces only if the FlipDuration property of RadBook is set to 0. 

To work this around set the FlipDuration to a bigger value. For example: FlipDuration="0:0:0.001"

The items of the RadComboBox control in the SettingsPane Text tab are not visible when the Windows8 theme is applied using StyleManager.

JavaScript actions causes a script to be compiled and executed by the JavaScript interpreter. Depending on the nature of the script, the values of the interactive form fields in the document can be validated or updated or the visual appearances of the fields can be changed.

At this point not much else is known other than the stack trace. The stack trace suggests that this happens on selection done by dragging the mouse and perhaps the document is with incorrect structure.
