This topic describes the Scheduler's appointment element and lists several properties that affect its visual appearance.

Generally, the Appointment is visually represented as a rectangle laying on the time cells of the scheduler area. The time cells it occupies correspond to its scheduled time interval. If an appointment is scheduled for a whole day (refer to the Appointment.AllDay property), or extends from one day to another, it is displayed in the All-Day Area of the Scheduler control.

The basic appearance of the appointment is illustrated below:

The appointment's visual elements are shown in the following picture:

The visual elements of the appointment and the corresponding properties are listed in the table below:

Visual Element Property
Height AppointmentDisplayOptions.AppointmentHeight. This property specifies the height of the rectange that represents an appointment, unless the AppointmentDisplayOptions.AppointmentAutoHeight property is set to true. For the Day View or Work Week View view types the appointment height depends on its duration when an appointment does not occupy the whole day. So the AppointmentHeight and AppointmentAutoHeight property is applicable only to the Appointment.AllDay type appointments in those views.
Start time Appointment.Start. The start of the scheduled time. If the Appointment.AllDay property is set to true, the start date of the appointment is the System.DateTime.Date of the Appointment.Start, and the start time of the appointment is 0:00. To hide the start time, use the AppointmentDisplayOptions.StartTimeVisibility property. The start and end time values can be displayed using a clock face instead of numbers - specify the AppointmentDisplayOptions.TimeDisplayType property as needed.
End time Appointment.End. The end of the scheduled time. To hide the end time, use the AppointmentDisplayOptions.EndTimeVisibility property. The start and end time values can be displayed using a clock face instead of numbers - specify the AppointmentDisplayOptions.TimeDisplayType property as needed.
Subject Appointment.Subject. A string that briefly characterizes the appointment.
Location Appointment.Location. A string that identifies the place for the scheduled event. When displayed, it is automatically enclosed in parentheses.
Description Appointment.Description. A block of text that provides the additional information about an appointment.
Reminder sign Appointment.HasReminder. Indicates that the appointment has an assigned reminder to provide a notification before the scheduled time occurs. Set this property to true to add the default Reminder to the appointment. To hide the reminder sign use the AppointmentDisplayOptions.ShowReminder property.
Recurrence Appointment.IsRecurring. If this property's value is true, then an appointment has an associated recurring pattern. (for more information refer to the Recurring Appointments and Exceptions topic). When the appointment's start or end time has been arbitrarily changed, the appointment does not conform to its recurrence pattern and it is indicated by the crossed recurrence sign. To hide the sign use the AppointmentDisplayOptions.ShowRecurrence property.
Status AppointmentDisplayOptions.StatusDisplayType. It may display the time status by its color, or the appointment's duration by the span of the colorized part along the time ruler (available for the Week View and Month View). The status element may also be hidden.
