Property Description
Panel Gets the processed dock panel.


A dock panel can serve as a container for other dock panels. In this case, the currently active dock panel is specified by its container panel’s DockPanel.ActiveChild property.

The ActiveChildChanged event fires in response to the container panel’s active child being changed. End-users can change the active child of a tab container by switching between its tabs. For split containers, they need to press the maximize button in its caption to maximize and activate a panel. These actions also be performed in code by setting the panel’s DockPanel.ActiveChild or DockPanel.ActiveChildIndex properties.
