TdxContainerDockSite.OnActiveChildChanged Event

Fires when the container’s active child control is changed.

Declaration

property OnActiveChildChanged: TdxActiveChildChangeEvent read; write;

Remarks

The OnActiveChildChanged event fires in response to changing the container’s active child. End-users can change the active child of a tab container by switching between tabs. For side containers, they need to maximize a control by pressing the maximize button in its caption. Note that the active child control can also be changed programmatically via:

• the container’s ActiveChildIndex and ActiveChild properties;

• the container site’s ActivateNextChild method.

The Sender parameter of the event represents the container whose active child has been changed. The newly active child can be accessed via the Child parameter.
