Ribbon tab page groups are collections of ribbon tab pages that contain commands related to specific common functionality or element, for example commands for tables, commands for images, etc.

As shown on the screenshot above, ribbon tab page groups can be easily distinguished from each other by the color of their stripe.

Ribbon tab page groups in NOV are implemented by the NRibbonTabPageGroup class and provide the following properties:

• Name - the name of the ribbon tab page group. It is used as a prefix to the text of the tab page headers (e.g. "Table - Design").
• StripeFill - the fill of the stripe shown at the top of the tab headers in this group. By default set to null.
• StripeHeight - the height of the tab page header stripe. By default set to 4 DIPs (default independent pixels).
• InactiveHeaderFill- the fill of inactive (not selected) tab page headers. By default set to null.
• TabPages - the collection of tab pages of this ribbon tab group.

The easiest way to create ribbon tab page groups is to use the constructor that accepts a name and a ribbon strip color:

NRibbonTabPageGroup tabGroup = new NRibbonTabPageGroup("Table", ENRibbonStripeColor.Yellow);
tabGroup.TabPages.Add(new NRibbonTabPage("Design"));
tabGroup.TabPages.Add(new NRibbonTabPage("Layout"));

The code above will create a ribbon tab page group with a yellow stripe. A 90% lighter color will be used for the fill of the inactive tab page headers.
