Allows you to customize the application-scope display and behavior settings for controls and components included in the XtraBars library - bars, dock panels, Ribbon controls, App UI Manager (DocumentManager) and tabbed windows (XtraTabbedMdiManager).
The DefaultBarAndDockingController component provides the application-scope LookAndFeel, appearance and customization settings for the controls and components included in the XtraBars library:

Application-Scope Settings
By default, all XtraBars controls/components within all forms get their default settings from a Default BarAndDockingController. This controller can be accessed at design time via the DefaultBarAndDockingController component, and in code via the BarAndDockingController.Default static property (returns a static instance of the BarAndDockingController class).

Form-Scope Settings
To specify the form-scope settings for the XtraBars controls/components, use the BarAndDockingController component. See this link to learn more.
