Assembly: DevExpress.XamarinForms.Scheduler.dll

    INotifyPropertyChanged

Related API Members

The following members return IRecurrenceInfo objects:

• AppointmentItem.RecurrenceInfo

Remarks

The pattern appointment’s AppointmentItem.RecurrenceInfo property provides data about the periodicity of occurrences generated by the pattern. The property returns instances of classes that implement the IRecurrenceInfo interface. Generally it is RecurrenceInfo objects.

The Scheduler View uses this information to generate occurrence appointments, and the OccurrenceCalculator can compute parameters of occurrences by these information.

All recurrence info properties are split into two groups:

• Properties that manage how long occurrences appear. The Range property manages which properties from this group the calculator uses to generate occurrences:

  RecurrenceRange Value	Used properties
  EndByDate	Start, End
  OccurrenceCount	Start, OccurrenceCount
  NoEndDate	Start

• Properties that manage how often occurrences appear. The Type property manages which properties from this group the calculator uses to generate occurrences:

  RecurrenceType Value	Used properties
  Daily	Periodicity, WeekDays
  Weekly	Periodicity, WeekDays
  Monthly	Periodicity, DayNumber, WeekDays, WeekOfMonth
  Yearly	DayNumber, Month, WeekDays, WeekOfMonth

Important

The AppointmentItem.RecurrenceInfo property returns null if AppointmentItem.Type is not Pattern.
