I am populating a Rad Scheduler using a WCF services, some of the items cannot be deleted so I have set AllowDelete to be false this does not seem to work and when I hover over the appointment the delete image still appears.

I have also tried to set some other information based on whether the appointment is a parent or child and this does not seem to work either, see my code below. The subject of the appointment changes to be either "Parent: ...." or "Child: ...." so the IF statement is working correctly. But the other changes I am trying to make do not seem to work correctly.

Am I adding the appointments incorrectly/is there another way to do this that will work.

Public Overloads Overrides Function GetAppointments(ByVal Owner As RadScheduler) As IEnumerable(Of Appointment)
     Dim AppointmentsList As New List(Of Appointment)
    'get a list of appointments to add and put them in the list above
    Do While Rs.ReadNext
        Dim AppointmentItem As New Appointment
        AppointmentItem.Start = Slot.Start_DT.Value
        AppointmentItem.End = Slot.End_DT.Value
        AppointmentItem.AllowEdit = False
        AppointmentItem.ID = Slot.GUI.Value
        If Slot.ParentGUI.IsNull Then
            AppointmentItem.Subject = "Parent: " & Slot.Name.Value
            AppointmentItem.AllowDelete = False
            AppointmentItem.ContextMenuID = "SchedulerAppointmentContextMenuDelete"
            AppointmentItem.Subject = "Child: " & Slot.Name.Value
            AppointmentItem.RecurrenceParentID = Slot.ParentGUI.Value
            AppointmentItem.AllowDelete = False
            AppointmentItem.BackColor = System.Drawing.Color.Black
            AppointmentItem.ForeColor = Drawing.Color.Pink
            AppointmentItem.ContextMenuID = "SchedulerAppointmentContextMenuNothing"
            ' have tried this too, AppointmentItem.ContextMenuID = Nothing
        End If
    Return AppointmentsList
End Function

Hello Andy,

When RadScheduler populates with WCF services the AppoinmentData object is used and that is why some of the options are not passed when they are set in the provider. That is why I will recommend you to set these settings in the onClientAppoinmentDataBound as it is shown in the last section of the SchedulerAppointment help topic.

Hope this will be helpful.
