When you create a custom View for a NavBar control, you can provide your own painter for group header signs. In this case, use TdxNavBarCustomSignPainter
or its descendant as the base class for your painter and override the InternalDrawSign method to draw the group header sign as your needs dictate. Refer to the Registering Custom Views topic for details.
