The Appointments property provides access to an object of theASPxAppointmentStorage type which represents the storage for appointment related information. Using the members of the ASPxAppointmentStorage object you can specify the data source that contains appointments (the ASPxAppointmentStorage.DataSource property), and access an object that allows properties of appointments to be mapped to the corresponding data fields (the ASPxAppointmentStorage.Mappings and ASPxAppointmentStorage.CustomFieldMappings properties).
