'Declaration Public ReadOnly Property TabGroups As MdiTabGroupsCollection
public MdiTabGroupsCollection TabGroups {get;}
MdiTabGroup objects are created and destroyed as needed. When all of the MdiTab objects in a tab group's Tabs collection have been closed, hidden or moved to other tab groups, the tab group is removed from the collection and released. When there are no tab groups and a tab is being displayed or when a tab is explicitly moved to a new tab group (e.g. using the MoveToNewGroup(MdiTab) method), a new MdiTabGroup is created and the InitializeTabGroup event is invoked to allow the tab group settings to be initialized.
Note: When an MdiTabGroup that contains child MdiTabGroups in its TabGroups only has 1 MdiTabGroup, the children of that tab group are promoted and the tab group that contained only the single child tab group is removed.
