Use an Edit form event script to specify a custom event for standard Isah data entry forms. You can specify a custom event for any of the following events.
Note: The BeforePost Event and the BeforeDelete Event will return a boolean as result. If the result of these functions is 'False', the respective 'Posting' or 'Deleting' will be aborted.
Note: Some events, such as the AfterApplyEvent, are called after several actions. You can use the updatekind property to differentiate between them.
