I create a new project i place a c1toolbar on the form dock it to the top of the form. Then on the c1commandholder1 that is created with the tool bar i set the visual style to office2007silver. Then place on a c1dockingTab on the from. In design mode the visual style of the docking table is office2007Silver. But when running the application in complied mode the tab control turn to system gray. Attached is and example.
