I am currently using the RadScheduler control to manage my own custom Appointments. The DataSource is set to an enumerable collection of my TSAppointment class. All the DataSourceField properties are set to the correct object properties. When I look at the SQL record or object record that is supplying Appointments to the Scheduler, the RecurrenceRule is NULL and the RecurrenceParentID is NULL. However, the appointment rendered on the Scheduler appears as if it were an edited instance in a recurring series. Specifically, it has the icon that looks like the recurring 'arrow' with a slash through it. Subsequently, when I double click to edit, it shows the confirmation dialog asking if I want to edit this instance or the entire series. Am I missing something?
