Description
Occurs when another control is dragged over the control.
Write code in the OnDockOver event to indicate whether a dockable control that is dragged over the windowed control can be accepted as a dock client. OnDockOver occurs after the TDragDockObject has been initialized by an OnGetSiteInfo event.
OnDockOver occurs only if DockSite is true.
