Tab Group
A Tab Group is a contextual control that is hidden or displayed at run time, based on a document or workspace state. The Tab Group contains a set of context-related Tab controls.
Details
Typically, a Tab Group is displayed during specific document or workspace states, such as when a user selects a particular object type. For example, the selection of an image contained in the header of a table might require various contextual tabs to be displayed that expose both table and image functionality.
Important
A Tab Group does not support application modes. However, the individual Tab controls within a Tab Group may.

Tab Group Properties
The Ribbon framework defines a collection of property keys for the Tab Group control.
Typically, a Tab Group property is updated in the ribbon UI by invalidating the Command associated with the control through a call to the IUIFramework::InvalidateUICommand method. The invalidation event is handled, and the property updates defined, by the IUICommandHandler::UpdateProperty callback method.
The IUICommandHandler::UpdateProperty callback method is not executed, and the application queried for an updated property value, until the property is required by the framework. For example, when a tab is activated and a control revealed in the ribbon UI, or when a tooltip is displayed.
Note
In some cases, a property can be retrieved through the IUIFramework::GetUICommandProperty method and set with the IUIFramework::SetUICommandProperty method.
The following table lists the property keys that are associated with the Tab Group control.
| Property Key | Notes |
