Ribbon Groups help define your tool structure on a more narrow level. Ribbon Tabs give your end user an idea of what task they want to perform, but the Group takes their idea one level deeper. You may be using xamRibbon™ for a word-processing application, and you may have a Formatting Tab. Inside the Formatting Tab, you could have several Groups of tools relating to the format of your end user’s document. You might have a Fonts Group or a Paragraph Group. You can add an entire Group to the Quick Access Toolbar (QAT) by setting a QatPlaceholderTool’s TargetID to the Group’s ID. You can also add a special button to the right side of the Group’s header which can launch a dialog box of your choosing.
