Public Event FilterAppointment As FilterAppointmentEventHandler

The FilterAppointment event's data class is FilterAppointmentEventArgs. The following properties provide information specific to this event:

Property	Description
Appointment	The appointment for which the event is raised.
Scheduler	The scheduler that raised the event.
View	The scheduler’s view that raised the event.
Visible	Specifies whether to display the appointment for which the event is raised.

The Appointment property returns the appointment for which the event is raised. Set the Visible property to false to hide this appointment.

If the appointment is hidden by the SchedulerControl.AppointmentFilterCriteria or SchedulerControl.AppointmentFilterString property, the event’s Visible property returns false. Set the Visible property to true to override the filter criteria/expression.

For regular occurrences, the FilterAppointment event is raised only once. In this scenario, the Appointment property returns the pattern.
