Thank you for writing.
The purpose of a recurrence rule is to affect all appointments that belong to it. In order to make an appointment differ from the common rule, you can create an exception to the MasterEvent.Exceptions
collection. Additional information is available in the following help article: http://docs.telerik.com/devtools/winforms/scheduler/appointments-and-dialogs/working-with-recurring-appointments
Here is a sample code snippet for your reference:
Appointment recurringAppointment =
DailyRecurrenceRule rrule =
DailyRecurrenceRule(recurringAppointment.Start, 1, 10);
recurringAppointment.RecurrenceRule = rrule;
ev.Start = ev.Start.AddHours(1);
ev.End = ev.End.AddHours(1);
I hope this information helps. Should you have further questions I would be glad to help.
