Hello community!

Attached please find the file "XamDialogAsMessageBox_V2XamDialogAsMessageBox_V2.rar.rar" that contains an example.

I want to Display a UI blocking Message Box that Returns as result which button was pressed by the user. So far the example is working but I have a question concerning the theming. 

In the main window I have 4 Buttons placed to set differents themes (Metro, MetroDark, Office Blue, IG). When one of those Buttons is pressed, the theme is set through the Infragistics ThemeManager. But the theme is not applied to the DialogView.

For Tests I added a method to the Dialog window in which the TemeManager.ApplicationTheme is set again --> No luck.
Next step, I add the <ThemeName>.xamDialogWindow.xaml to the local Resources as shown in the Theming sample of the DialogWindow .

Well, the background Color of the Buttons is changed. What have I missed?
