Selects the next appointment within the visible area of the view.
The SelectNextAppointment method allows the appointment after the currently selected one to be selected. If no appointment is currently selected, the next appointment whose start time is greater than the start time of the selected time interval is selected.
To select the previous appointment, use the SchedulerControl.SelectPrevAppointment method.
End-users can use the TAB and TAB+SHIFT keys to select the next and previous appointments, respectively.
Each time the selection changes, the SchedulerControl.SelectionChanged event is raised.
The SelectNextAppointment method is analogous to the TAB key switching in that it selecs appointments within the visible range only.
