How to identify Recurrence deletion

[Art Kedzierski]

In my custom RadScheduleView deployment, I allow RecurrencePatterns but not RecurrenceExceptions. When a user attempts to edit/delete an appointment series, I want to bypass the RecurrenceChoiceDialog and go directly to the series (in the case of an edit) or pop up a simple "Delete series?" confirmation if a deletion. I can tell when an RecurrenceChoiceDialog is being fired, but I cannot figure out whether it is initiating an edit or delete event.

public void Appointment_ShowDialog(object sender, ShowDialogEventArgs e)
{
    var rcdvm = e.DialogViewModel as RecurrenceChoiceDialogViewModel;
    if (rcdvm != null)
    {
        rcdvm.IsSeriesModeSelected = true;
        e.DefaultDialogResult = true;
        e.Cancel = true;
    }
}

  
This code works fine for jumping straight to the EditAppointmentDialog in the case of an edit, but how do I determine if it's a deletion?

I think I figured it out. It's RecurrenceChoiceDialogMode (which has no documentation describing its function, merely its existence). That and a custom  RecurrenceChoiceDeleteDialogStyle should do the trick.

public void Appointment_ShowDialog(object sender, ShowDialogEventArgs e)
{
    var rcdvm = e.DialogViewModel as RecurrenceChoiceDialogViewModel;
    if (rcdvm != null && rcdvm.RecurrenceChoiceDialogMode == RecurrenceChoiceDialogMode.Opening)
    {
        rcdvm.IsSeriesModeSelected = true;
        e.DefaultDialogResult = true;
        e.Cancel = true;
    }
    else if (rcdvm != null && rcdvm.RecurrenceChoiceDialogMode == RecurrenceChoiceDialogMode.Deleting)
    {
        rcdvm.IsSeriesModeSelected = true;
    }
}
