Deleting only this ocurrence returns wrong exception date

[Oleg]

Hi,
     I am trying to delete only a single occurrence within a recurring appointment in the ASP RadScheduler. If I click on any ocurrence past the second one, the AppointmentUpdate event returns a ModifiedAppointment object whose RecurrenceRule property contains the date of the second ocurrence. So what winds up happening is that if I click on the third, or fourth or any ocurrence beyond the second, the second ocurrence winds up getting deleted. Am I doing something wrong or is this an issue? If it is an issue, is there a fix or a work-around?

Thanks,
Oleg Litvak

Hello Oleg,

When alter / delete an appointment which belong to a recurring series, an exception for that appointment is created. More information about this could be found at the following link: RadScheduler / Working with Recurring Appointments.

Could you check the online demos to see if the same behavior is replicated in there, too?

Kind regards,

Hi Ivana,
      The demo site does not show the same problem. So it must be something in my code. Here is a snippet of my code:

Protected Sub RadScheduler2_AppointmentUpdate(ByVal sender As Object, ByVal e As Telerik.Web.UI.AppointmentUpdateEventArgs) Handles RadScheduler2.AppointmentUpdate
       SaveFacilityReservation(e.ModifiedAppointment)
End Sub

Private Sub SaveFacilityReservation(ByVal appt As Appointment)
     If appt.RecurrenceRule.Length > 0 Then
          Dim rec As RecurrenceRule = RecurrenceRule.TryParse(appt.RecurrenceRule)
            If appt.ID > 0 And appt.RecurrenceState = RecurrenceState.Exception Then
                 For Each exc As Date In rec.Exceptions
                      'Delete each facility reservation corresponding to each exception
                 Next
            End If
     End If
End Sub

Should I be using a different way of parsing the appointment exceptions?

Thanks,
Oleg

Hello Oleg,

The video below shows how the RadScheduler behaves when deleting recurring appointments: RadScheduler / Recurring Appointments. Could you test if this behavior can be replicated if you remove the custom code which handles the recurring appointments deleting?

If the issues still persist, you can isolate the problem in a sample project and send it to us. Or, send us a live URL to your website.

Kind regards,
