Arranging Appointments on Drop

[Rod Yager]

I have two sources for dragging and dropping appointments onto the ScheduleView. Both consist of dragging custom appt objects so they both utilize a custom dragdrop handler class and use the override of the ConvertDraggedData method. I am wondering if it would be possible to arrange the appts in such a way that if I grabbed appts from all over the view and then dragged them to a specific resource at a specific time, If I could then just have them updated in such a way that the appts were dropped one after another in the view (stacked horizontally in timeline view for example). I think the issue I am having is that destination slots need to be updated somehow to reflect where I want the appts to eventually be. Hopefully this isn't too confusing and someone can lead me in the right direction. Here is a bit of code that I wrote but obviously it isn't working like I expect at this point. I am basically trying to re-arrange the appts so that one comes right after another when they are dropped. The collection looks like I expect when it comes out of my ArrageTasks, but the result is the appts still end up in slots all over the view.

public override IEnumerable<IOccurrence> ConvertDraggedData(object data)
        {
            if (data.GetType() == typeof(DataObject))
            {
                return ArrangeTasks(data);
                //return (data as DataObject).GetData("MetrixTaskAppointments") as IList<IOccurrence>;
            }

            return base.ConvertDraggedData(data);
        }

        private IEnumerable<IOccurrence> ArrangeTasks(object data)
        {
            IList<IOccurrence> appts = (data as DataObject).GetData("MetrixTaskAppointments") as IList<IOccurrence>;
            IEnumerable<IOccurrence> sortedAppts = appts.OrderBy(f => f.Start);

            IEnumerator apptEnumerator = sortedAppts.GetEnumerator();
            DateTime savedPlanTravelEndDttm = DateTime.Now;
            bool firstTask = true;
            while (apptEnumerator.MoveNext())
            {
                MetrixTaskAppointment mAppt = (MetrixTaskAppointment)apptEnumerator.Current;
                IAppointment appt = (Appointment)apptEnumerator.Current;

                if (firstTask == true)
                {
                    firstTask = false;
                }
                else
                {
                    mAppt.PlanTravelStartDttm = savedPlanTravelEndDttm;
                    mAppt.PlanStartDttm = mAppt.PlanTravelStartDttm.AddMinutes(mAppt.PlanTravelToMin);
                    mAppt.PlanEndDttm = mAppt.PlanStartDttm.AddMinutes(mAppt.PlanTaskDurMin);
                    mAppt.PlanTravelEndDttm = mAppt.PlanEndDttm.AddMinutes(mAppt.PlanTravelReturnMin);
                    appt.Start = mAppt.PlanStartDttm;
                    appt.End = mAppt.PlanEndDttm;
                }

                savedPlanTravelEndDttm = mAppt.PlanTravelEndDttm;
            }

            return sortedAppts;

        }
