Scheduler appointment spanning over for 2 days

Hi,

I created an appointment in a multiDayView. I have no problem if the appointment duration is within the same day. However, if I span the appointment across two days, the appointment disappeared after I choose dayView or weekView and then move back to multiView. Below is the code snippet of my multiDayView routine. Any help is appreciated. Thanks

            SchedulerMultiDayView multiDayView = new SchedulerMultiDayView();
            this.radScheduler1.ActiveViewType = SchedulerViewType.MultiDay;            
            DateTime current = radCalendar1.SelectedDate;
            this.radScheduler1.ActiveView = multiDayView;
            multiDayView.Intervals.Add(current, 3);       
            multiDayView.ShowAllDayArea = false;
