a issue delete an instance of a recurring event

[william]

When i want to delete an instance of a recurring event, the fuction "theScheduler_AppointmentUpdate" will  fired . My code is as bellow ,

void theScheduler_AppointmentUpdate(object sender, AppointmentUpdateEventArgs e)

{

  Appointment appointment = e.Appointment; 

  // People resizing 
  SPListItem li = GetListItem(appointment);


 
  if (appointment.RecurrenceState == RecurrenceState.Master)

  {

     // This means somebody try to delete an instance of recurring event                    

     RecurrenceRule recRule;

     RecurrenceRule.TryParse(appointment.RecurrenceRule, out recRule);

     if (recRule != null && recRule.Exceptions.Count > 0)

     {

        // The last exception is the DateTime of the deleted appointment

        DateTime deletedDateTime = recRule.Exceptions[recRule.Exceptions.Count - 1];

        CreateDeletedAppointment(deletedDateTime, appointment, li);

     }

   }

}

I find that the recRule.Exceptions always equal to 0 . Can somebody help me with this issue ? (I know that the "Exceptions" is created when we edit a recurring appointment)

I debug my code , i notice that "e.Appointment.Start" is "4/22/2006 7:00:00 AM" , actually it should be "4/22/2011 7:00:00 AM"  . Is anyone knows the reason? Any suggestion is appreciate  .

Hello William,

Can you examine e.ModifiedAppointment? Do you still experience problems?
