This event is triggered when the form is being loaded or printed.
All the objects of the form (from any page) whose
On Load object event property is selected will have their object method called. Then, if the
On Load form event property is selected, the form will have its form method called.
On Unloadevents are generated for objects if they are enabled for both the objects and the form to which the objects belong. If the events are enabled for objects only, they will not occur; these two events must also be enabled at the form level.
On Load event is generated when opening the subform (this event must also have been activated at the parent form level in order to be taken into account). The event is generated before those of the parent form. Also note that, in accordance with the operating principles of form events, if the subform is placed on a page other than page 0 or 1, this event will only be generated when that page is displayed (and not when the form is displayed).
