DatePicker shows Time?

07-09-2009 11:23 AM |

I have bound the DatePicker to nullable datetime datamember of a wcf datacontract. I have a Fetch button that, when pressed, sets the datacontext and I see a date from my Oracle database.

If I then save the data using wcf to Oracle and press the Fetch button again, the DatePicker now shows a date AND time. If I just restart the app and Fetch the same record again, it doesn't display the time.

How can I permanently get it to just show the date?

Unfortunately, there won't be a way of doing this directly in the DatePicker control. While it does have a SelectedDateFormat property, this only accepts two values: Long and Short (default). Neither of these choices will remove the time from your display value. This means that you will need to format the value using either a wrapped property in your ViewModel, or a converter. If you go the converter route, I would suggest using a generic format converter, as opposed to a specific date format converter.

public class FormatConverter : IValueConverter

    #region IValueConverter Members

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

        if (parameter != null)

            string formatterString = parameter.ToString();

            if (!string.IsNullOrEmpty(formatterString))

                return string.Format(culture, formatterString, value);

        return value.ToString();

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

        return value;

    #endregion

<Grid>

    <Grid.Resources>

        <converters:FormatConverter

            x:Key="Converter_Format" />

    </Grid.Resources>

    <DatePicker

        Text="{Binding Path=SelectedDate, RelativeSource={RelativeSource Self}, Converter={StaticResource Converter_Format}, ConverterParameter=\{0:d\}}"
