同时使用silverlight datepicker和timepicker

我想,你可以用converter说DatePicker“在更改日期时离开时间组件”。当您绑定DateTime到DatePicker转换器时,它会存储值,并且在ConvertBack上返回而不更改时间部分。

public class DateConverter : IValueConverter
{
    private DateTime _original;

    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        _original = (DateTime)value;
        return value;
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        DateTime date = ((DateTime) value);
        return new DateTime(date.Year, date.Month, date.Day, _original.Hour, _original.Minute, _original.Second);
    }
}

XAML:

<sdk:DatePicker SelectedDate="{Binding Date, Mode=TwoWay, 
                Converter={StaticResource dateConverter}}" />

<input:TimePicker Value="{Binding Date, Mode=TwoWay}"/>
