TColorBox.OnCloseUp Event

Occurs when the drop-down list closes up due to some user action.

Pascal
property OnCloseUp: TNotifyEvent;
C++
__property TNotifyEvent OnCloseUp;

Write an OnCloseUp event handler to implement special processing that needs to occur when the drop-down list closes up. For example, an OnCloseUp event handler can check whether the user changed the selected item while the list was dropped down and respond accordingly.
