I have several XamTextEditor/XamComboEditor controls in a TabItemEx. Their values are binded to an object, like this: SelectedItem="{Binding Path=Status, UpdateSourceTrigger=LostFocus, ValidatesOnDataErrors=True}"
The object implements IDataErrorInfo. When the property has an error the control is surrounded by a thin red border. When I activate another tab and then go back to the tab with control with the error the border is gone. Even though object still has an error.
Any ideas?
I found a work around, I surrounded the control with <AdornerDecorator> tag and the border stays.
