Thank you for writing.
You can use the PropertyChanged event of the control to detect when the FocusedDate is getting changed (which will be changed when the arrow keys are pressed) and in it, set the control's SelectedDate:
sender, PropertyChangedEventArgs e)
radCalendar1.SelectedDate = radCalendar1.FocusedDate;
I hope that you find this information useful. Should you have any other questions, do not hesitate to contact us.
