Hello,

1. I create an appointment with recurrence : 3 occurrences A,B,C.
2. I update only one occurrence : B.
3. I delete B.

But deleting B doesn't work... indeed, no event is firing... (none from OnOccurrenceDelete​/OnAppointmentDelete/Delete method from provider)
More, if i try to edit this occurrence B, i can choose series/occurrence illogically (and nothing happen if i choose edting series...) 

If I update series from A or B to reset exception, the original B takes place, but my "orphan" occurrence B always exists and i still can not delete it.
The own way for user to delete orphan B is to add a reccurence to B then deleting the series...

Is it something i didn't understand ? ​How to force the removal of B please ?

Hello Luc,

Could you demonstrate us the implementation of the RadScheduler that you use at your and, along with the data-binding approach that you use. This we could get a clearer picture on your implementation and try to replicate the experienced issue.

In fact, i deleted this code from GetAppointments ​into the provider :

if (apt.RecurrenceParentID != null)
{
   apt.RecurrenceState = RecurrenceState.Exception;
}

 Because, for me, this ocurrence (previously moved from series) is now with a type NotRecuring.
And it's working great like this.

The original code is here :

http://docs.telerik.com/devtools/aspnet-ajax/controls/scheduler/data-binding/providers/implementing-a-provider-that-supports-multi-valued-resources

To answer to you previous post, this is a part of my code for the GetAppointments method :

public override IEnumerable<Appointment> GetAppointments(RadScheduler owner)
{
    List<Appointment> appointments = new List<Appointment>();
    List<CAppointmentInfo> appointmentInfos = new List<CAppointmentInfo>();
    List<CAppointmentInfo> uniqueAppointmentInfos = AppointmentInfos.Where(x => x.Start >= owner.VisibleRangeStart && x.End <= owner.VisibleRangeEnd && x.RecurrenceRule == string.Empty).ToList();
    List<CAppointmentInfo> recurrenceAppointmentInfos = AppointmentInfos.Where(x => x.RecurrenceRule != string.Empty).ToList();
    appointmentInfos.AddRange(uniqueAppointmentInfos);
    appointmentInfos.AddRange(recurrenceAppointmentInfos);
 
    foreach (CAppointmentInfo appointmentInfo in appointmentInfos)
    {
        Appointment apt = new Appointment();
        apt.Owner = owner;
        apt.ID = appointmentInfo.ID;
        apt.Subject = appointmentInfo.Subject;
        apt.Start = DateTime.SpecifyKind(appointmentInfo.Start, DateTimeKind.Utc);
        apt.End = DateTime.SpecifyKind(appointmentInfo.End, DateTimeKind.Utc);
        apt.RecurrenceRule = appointmentInfo.RecurrenceRule;
        apt.RecurrenceParentID = appointmentInfo.RecurrenceParentID;
        if (appointmentInfo.Reminder != null)
        {
            IList<Reminder> reminders = Reminder.TryParse(appointmentInfo.Reminder);
            if (reminders != null)
            {
                apt.Reminders.AddRange(reminders);
            }
        }
 
        if (apt.RecurrenceRule != string.Empty)
        {
            apt.RecurrenceState = RecurrenceState.Master;
        }
 
        LoadResources(appointmentInfo, apt);
        appointments.Add(apt);
    }
 
    return appointments;
}
