protected property TCustomComboBox.OnCloseUp : TNotifyEvent |
OnCloseUp is a TNotifyEvent property which contains the event handler signalled when the drop-down list in the control is hidden or closed. It can be used to perform any actions needed in an application, such as comparing pre-selection and post-selection values for properties. An application must implement and assign an object procedure to the property to respond to the event notification.
