The RibbonBar control enables you to create ribbons which are a modern way of organizing user commands in user interfaces. It is composed of Category, Panel, Group, LargeButton (with or without RibbonMenu), SmallButton (with or without RibbonMenu), CheckBox, ComboBox, TabButton (with or without RibbonMenu), and Spin (currently unsupported).
To help developers create a ribbon efficiently, a tool called "RibbonBar Builder" is provided. The RibbonBar Builder allows developer to modify the RibbonBar control template in an XML editor while preview its graphical UI on the fly.
For more details, refer to the section called “RibbonBar control” in Objects and Controls and the section called “Working with RibbonBar” in Users Guide.
