Hide if DateTime value is minValue

[John]

Telerikers,
I do have a radgridview with one RadDateTimepicker control on it.  the RadDateTimepicker control binds it correctly in EDIT mode.  However, when the data returns as minvalue from DB (1/1/0001), I would like to hide it and keep the RadDateTimepicker box blank. 

See attachment for details. http://i12.photobucket.com/albums/a201/le9569/1-3.png

Your guidance is appreciated.
John.

For those who need solution, change the DateTime type to DateTime? type in the object.  It would do the trick.

Hello John,

In addition to this use the SelectedValue as a recommendation instead of the SelectedDate.

Kind regards,

Just wondering if anyone has some other solution?  Since the database column is not nullable, the entity model just sue DateTime instead of DateTime?.  So everytime I try to create a new object it will be bound to the MinValue.

Add a converter should work:

public class MinDateConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        if (value == null)
            return null;

        if (value.GetType() == typeof(DateTime))
        {
            var d = DateTime.Parse(value.ToString());
            if (d == DateTime.MinValue) return null;
            return d;
        }

        return null;
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        // Not needed;
        if (value == null)
            return DateTime.MinValue;

        return value;
    }
}
