Hi Mario,
The DockingManager has a event named ProvideGraphicsItems events,helps to customize the caption bar of the docked control window.
The DockingManager.ProvideGraphicsItems events fired whenever a dockable control''s caption needs to be painted.
To change the title color of the Docked control window(ListBox control), you could handle the ProvideGraphicsItems event.
I have attached the sample,please go through that,let me know you need further assistance.
