You are viewing documentation for the legacy WPF Scheduler control. If you're starting a new project, we strongly recommend that you use a new control declared in the DevExpress.Xpf.Scheduling namespace. If you decide to upgrade an existing project in order to switch to the updated scheduler control, see the Migration Guidelines document.
Maps to the PersistentObject.Id property. Appointment identity. Should be unique. This mapping is required for the Gantt View only to establish and maintain appointment relations. Other views, the SchedulerStorage and built-in appointment operations do not use the value of the Appointment.Id property. Therefore, if your application relies on Appointment.Id, you should provide methods for assigning the ID and updating the underlying data source with the actual ID value, as described in the PersistentObject.Id article.
Maps to the Appointment.RecurrenceInfo property. Not required. The data is a list of attributes with values. If the appointment is the first in the chain, the data contains a unique pattern identifier, and parameters that describe the recurrence pattern. If the appointment is not the first member in a chain, the data contains a pattern identifier and the index in the chain.
