The MaxTabGroups determines the maximum number of MdiTabGroup objects that contain MdiTab object can be created.
Note: This limitation is imposed both programatically and via the ui. In other words, the options to move a tab to a "New Horizontal Tab Group" or "New Vertical Tab Group" will not be included in the context menu if there are already the MaxTabGroups number of MdiTabGroup objects (in the TabGroups collection or within the TabGroups of nested MdiTabGroups) with MdiTab objects in their Tabs collection. Also, an exception will be raised if an attempt to programmatically move a tab to a new tab group (e.g. MoveToNewGroup(MdiTab)) is made.
