StdFormPredisplay event
Occurs when a form opens, after Windows client has loaded the components from their data sources but before the collections on the form are initialized, the initial command is executed, and component values are displayed on the screen.
The event is not associated with a default handler and is for notification only.
Remarks
The event is the first event to fire during initialization of a non-query form.
Note: In the web client, this event might actually be fired after the form is displayed.
The timing is otherwise correct in relation to the overall sequence of events. However,
the name implies this will be executed before the form is made visible, which is not the
case in the web client.
In Design Mode, the event is fired and any handlers associated with it are executed when you regenerate a form (on the menu, click ).
