Example

This code snippet illustrates how to set the appointment’s recurrence info from XML string using the IRecurrenceInfo.FromXml method and create an IRecurrenceInfo object using the RecurrenceInfoXmlPersistenceHelper class.

Recurrence.cs

string head = "<RecurrenceInfo ";
string startText = String.Format("Start = '{0}' " , DateTime.Today.AddHours(3));
string endText = String.Format("End = '{0}' ", DateTime.Today.AddHours(4));
string weekDays = String.Format("Weekdays='{0}' ", 10);
string id = String.Format("Id = '{0}' ", Guid.NewGuid());
string occurrenceCount = String.Format("OccurrenceCount = '{0}' ", 15);
string periodicity = String.Format("Periodicity = '{0}' ", 2);
string range = String.Format("Range = '{0}' ", 1);
string type = String.Format("Type = '{0}' ", 1);
string version = String.Format("Version = '{0}' ", 1);
string tail = " />";
string recurrenceXmlString = (head + startText + endText + weekDays +
    id + occurrenceCount + periodicity + range + type + version + tail).Replace("'", "\"");
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 = "Recurrence From XML";

// Set appointment recurrence from XML.
apt.RecurrenceInfo.FromXml(recurrenceXmlString);
// Get recurrence info from XML.
IRecurrenceInfo rec = DevExpress.XtraScheduler.Xml.RecurrenceInfoXmlPersistenceHelper.ObjectFromXml(recurrenceXmlString);

apt.Description = recurrenceXmlString + Environment.NewLine + String.Format("Type: {0}",rec.Type);
scheduler.Storage.Appointments.Add(apt);
