Hi,
I'm testing the 20days trial to decide to buy or not the ultimate suite.
I've a problem to define a custom Appointment dialog using XamlScheduleView.
I've defined:

 class MyScheduleDialogFactory : ScheduleDialogFactoryBase
    {
        public override ActivityTypes SupportedActivityDialogTypes
        {
            get { return ActivityTypes.Appointment; }
        }

        public override FrameworkElement CreateActivityDialog(FrameworkElement container, XamScheduleDataManager dataManager, ActivityBase activity, bool allowModifications, bool allowRemove)
        {
            switch (activity.ActivityType)
            {
                case ActivityType.Appointment:
                    {
                        // Create the element that represents
                        // the contents of the dialog
                        var vm = new ScheduleAppointmentViewModel() { Activity = activity, AllowModifications = allowModifications, AllowRemove = allowRemove, Container = container, DataManager = dataManager };
                        return new ScheduleAppointmentWindow(vm);
                    }
                default:
                    {
                        // Return null for unsupported activity types.
                        return null;
                    }
            }
        }

    }
 
The ScheduleAppointmentWindow extends Window.
The question is, how can I save/add new appointment by this window? 
I've tried to:  var act = DataManager.CreateNew(ActivityType.Appointment, out dei);
and then filling the properties of "act", but I don't view the new activity in the schedule calendar
