Changing background color of certain appointments in RadScheduler agenda view

[Cathal]

I have a radscheduler with agenda view. I want to change the color of certain rows like such: http://imgur.com/a/2ot4X

This is my radScheduler :

This is my c# code but the color is currently never changing:

protected void rs_Calendar_AppointmentDataBound(object sender, SchedulerEventArgs e)
 if (e.Appointment.DataItem is vw_CalendarDate)
  vw_CalendarDate ce = (vw_CalendarDate)e.Appointment.DataItem;
  if (ce.Title != null && ce.Title.ToLower().StartsWith("sgt"))
   e.Appointment.BackColor = Color.Red;
 }
}
