Create Appt Exception Multiple DialogClosing Events

[Cliff McManus]

When I drag an appointment to create an exception I receive the DialogClosing event from the RecurrenceChoiceDialog as expected.

However immediately after receiving this message I next receive two DialogClosing events of type RecurrenceDialogViewModel.



This is confusing to me. Is this functionality standard or might I be doing something wrong?



Here is a copy of my code for this method

#region xScheduleView_DialogClosing
        //DialogClosing - occurs when a ScheduleView dialog is about to be closed. The DialogClosing event handler receives two arguments: 
        // 1. The sender argument contains the RadScheduleView. This argument is of type object, but can be cast to the RadScheduleView type. 
        // 2. An CancelRoutedEventArgs object. After casting the CancelRoutedEventArgs to CloseDialogEventArgs you can access the following properties
        //    DialogViewModel - gets the scheduler dialog. The property can be cast to the following types: 
        //        1.AppointmentDialogViewModel
        //        2.RecurrenceChoiceDialogViewModel
        //        3.RecurrenceDialogViewModel
        //        4.ConfirmDialogViewModel
        //   Cancel - set this boolean property to True, when you want to cancel the event
 
        private void xScheduleView_DialogClosing(object sender, CancelRoutedEventArgs e)
        {               
            if ((((DialogEventArgs)e).DialogViewModel) is RecurrenceChoiceDialogViewModel)
            {
                // Returned from Recurrence Choice Dialog (Choose Occurrence or Series)
                RecurrenceChoiceDialogViewModel rCDVM = (((DialogEventArgs)e).DialogViewModel as RecurrenceChoiceDialogViewModel);
 
                if (rCDVM.IsOccurrenceModeSelected == true)
                {
                    // User selected to modify the Occurrence/exception
                    if ((rCDVM.RecurrenceChoiceDialogMode == RecurrenceChoiceDialogMode.Deleting))
                    {
                        functionBeingExecuted = FUNCTION_BEING_EXECUTED.DELETE;
                        if (rCDVM.Occurrence.OriginalStart == DateTime.MinValue)
                        {
                            // Recurring Appointment being deleted
                            functionBeingExecuted = FUNCTION_BEING_EXECUTED.ADD;
                            appointmentType       = APPOINTMENT_TYPE.OCCURRENCE;
                            //exceptionDateTime     = rCDVM.Occurrence.Start;

                        else

                        }
                    }

Hi Cliff,

Thank you for reporting this issue to us.

I have logged it in our feedback portal where you could track its status. We will do our best to fix it for the next release.

I reworked my logic and simplified it greatly. I believe this to be an artifact of my convoluted logic rather than a telerik problem.

Item can be closed.
