I have following style applied for all my RadMultiColumnComboBox controls (in the app.xaml):
With this style applied, I get this error in my XAML files (see attached file): The element "[RadMultiColumnComboBox]" could not be displayed because of a problem with System.Windows.StaticResourceExtension: CollectionView must have value. Parameter name: collectionView.
The error is provoced by the setter of the AutoCompleteMode. The error disappears when this setter is deleted.
Setting the AutoCompleteMode directly on a RadMultiColumnComboBox (with the style applied) does not cause any problems.
Any ideas ??
