We are aware of this discrepancy with RadDatePicker control type. We tried to register the control as DatePicker/DateTimePicker, but we failed due to some framework limitations. There is no such type in the AutomationControlType enum so we fallback to Custom. We know that the MS DatePicker control is read as DatePicker in the coded UI recorder and we contacted Microsoft if we can get more information how to do the same with the RadDatePicker/RadDateTimePicker control. We haven't received an answer from them for now and we are still waiting. Hopefully they will send us the required information and we will update our code as well.
