NOV Schedule provides support for notifications. Notifications are messages shown a given period of time before the start of an appointment. In order to enable the display of notifications, you should set the NotificationCheckInterval property of the schedule view to a positive number. This number represents the time interval in seconds at which the schedule view should check for notifications. A commonly used value is 60, which means that the schedule view will check for notifications every minute. If set to 0 (the default value) or a negative number, the schedule view will not check for and will not show any notifications.

scheduleView.NotificationCheckInterval = 60;

To assign a notification to an appointment simply set its Notification property to a time span value, for example 10 minutes. Thus 10 minutes before the start of the appointment the NOV schedule will show a dialog with a list of the upcoming appointments in which this and any other notifications will be shown.

appointment.Notification = TimeSpan.FromMinutes(10);
