RadDiagramRibbonBar is a ribbon control that has been wired to work with the API that RadDiagram exposes.
RadDiagramRibbonBar can be found in the Toolbox of Visual Studio, if you have installed the controls automatically. In order to use it, drag an instance of the RadDiagramRibbonBar in the designer area and drop it. Then, you can set the associated RadDiagram by either using the smart tag or setting the AssociatedDiagram property.
RadDiagramRibbonBar introduces UI for saving and loading predefined diagramming layouts. Additionally, you can manipulate the ZOrder of the shapes and perform clipboard operations.
