I use custom form when edit appointment. (use EditAppointmentFormShowing event)
My custom field appointmentID is primary key in my appointment table.
When ApplyChanges() call then create record and also appointmentID get new value.
But this field is custom field.
---------------------------------------------------------------------------
public class AppController : AppointmentFormController
{
...
}
---------------------------------------------------------------------------
AppController controller;
//input new values...
controller.ApplyChanges() ;
// then how to know my custom field value?
