The dock panels can serve as a container for other dock panels. In this case, the currently active dock panel is specified by its container panel’s ActiveChild property. Note that only one active dock panel can be displayed on a container dock panel at a time.
The active child panel can also be specified using the DockPanel.ActiveChildIndex property.
End-users can change the active child of a tab container by switching between tabs. For a split container, they need to maximize a dock panel by pressing the maximize ( ) button in its caption.
