            case EditPatternAction:
                PushEditAppointmentPage(storage.GetPattern(e.AppointmentInfo.Appointment));
                break;
            case EditOccurrenceAction:

                PushEditAppointmentPage(e.AppointmentInfo.Appointment);
                break;

    var page = new AppointmentEditPage(info.Start, info.End, info.AllDay, storage);
    await Navigation.PushAsync(page);
