Hello,

I have been looking into this for you and did replicate the behavior you described.  This can be overcome by creating a converter of your own and setting it to the XamDateTimeEditor’s ValueToDisplayTextConverter property. I did some more research and was able to create a converter for you to achieve your goal:

    public class DTtoString : IValueConverter

    {

        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

        {

            if (value != null)

            {

                DateTime temp = new DateTime();

                if (DateTime.TryParse(value.ToString(), out temp))

                {

                    if (temp == (parameter as XamDateTimeEditor).ComputedMinDate)

                    {

                        return null;

                    }

                    return temp.ToString(culture);

                }

                return null;

            }

            else return null;     

        }

        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

        {

            return value;

        }

    }

Please let me know if I can assist you further on the matter.
