Form dialog events

Use this code event to manage the action state for actions defined for the form, by setting an action as active (setActionActive/ TRUE|FALSE) or hidden (setActionHidden/ TRUE|FALSE).

If you have other actions defined for the form, you can also set their state in this code event.

The state of an action is determined by the relation setting (disable Add, disable Modify, disable Delete, disable Search).

This event is triggered after UI synchronization following validation of a CRUD operation.
