Fires after the focused node has been changed.
public event EventHandler FocusedNodeChanged
Public Event FocusedNodeChanged As EventHandler
The FocusedNodeChanged event's data class is EventArgs.
The FocusedNodeChanged event is raised when an end-user moves focus from one node to another.
If the TreeListSettingsBehavior.ProcessFocusedNodeChangedOnServer property is set to false, the ASPxClientTreeList.FocusedNodeChanged event is handled on the client side without a callback to the server. Setting this property to true indicates that the final processing of the event should be performed on the server side, and so a round trip to the server is required. During such a round trip the corresponding server-side FocusedNodeChanged event is fired, which if handled, allows any desired server-side action to be performed.
