Example

This example illustrates the use of the IRecurrenceInfo.ToXml method to obtain recurrence info in XML format.

Recurrence.cs

scheduler.Storage.Appointments.Clear();
Appointment apt = scheduler.Storage.CreateAppointment(AppointmentType.Pattern);
apt.Start = DateTime.Today.AddHours(3);
apt.End = apt.Start.AddHours(2);
apt.Subject = "TEST";

apt.RecurrenceInfo.Type = RecurrenceType.Weekly;
apt.RecurrenceInfo.Start = apt.Start;
apt.RecurrenceInfo.Periodicity = 2;
apt.RecurrenceInfo.WeekDays = WeekDays.Monday | WeekDays.Wednesday;
apt.RecurrenceInfo.Range = RecurrenceRange.OccurrenceCount;
apt.RecurrenceInfo.OccurrenceCount = 15;

string s = DevExpress.XtraScheduler.iCalendar.iCalendarHelper.ExtractRecurrenceRule(apt.RecurrenceInfo);
apt.Description = "RRULE:" + s + Environment.NewLine;
scheduler.Storage.Appointments.Add(apt);
apt.Description += apt.RecurrenceInfo.ToXml();

Recurrence.vb

scheduler.Storage.Appointments.Clear()
Dim apt As Appointment = scheduler.Storage.CreateAppointment(AppointmentType.Pattern)
apt.Start = Date.Today.AddHours(3)
apt.End = apt.Start.AddHours(2)
apt.Subject = "TEST"

apt.RecurrenceInfo.Type = RecurrenceType.Weekly
apt.RecurrenceInfo.Start = apt.Start
apt.RecurrenceInfo.Periodicity = 2
apt.RecurrenceInfo.WeekDays = WeekDays.Monday Or WeekDays.Wednesday
apt.RecurrenceInfo.Range = RecurrenceRange.OccurrenceCount
apt.RecurrenceInfo.OccurrenceCount = 15

Dim s As String = DevExpress.XtraScheduler.iCalendar.iCalendarHelper.ExtractRecurrenceRule(apt.RecurrenceInfo)
apt.Description = "RRULE:" & s & Environment.NewLine
scheduler.Storage.Appointments.Add(apt)
apt.Description += apt.RecurrenceInfo.ToXml()
