Question

我有这个DataGridCell，它调用这个转换器。我期待这个细胞的价值是＆＃34;嗨＆＃34; （当我通过转换器在数据网格中显示时，我将单元格＆＃34;内容＆＃34;设置为＆＃34; hi＆＃34;）。

我在这里做错了什么？

<DataGridTextColumn Width="60" Header="Google" CanUserResize="True" CanUserSort="True">
    <DataGridTextColumn.HeaderStyle>
        <Style TargetType="{x:Type DataGridColumnHeader}">
            <Setter Property="ToolTip" Value="Current Position on Google" />
            <Setter Property="HorizontalContentAlignment" Value="Center"/>
        </Style>
    </DataGridTextColumn.HeaderStyle>
    <DataGridTextColumn.CellStyle>
        <Style TargetType="{x:Type DataGridCell}">
            <Setter Property="HorizontalAlignment" Value="Center"/>
            <Setter Property="FontSize" Value="12"/>
            <Setter Property="VerticalAlignment" Value="Center"/>
            <EventSetter Event="MouseUp" Handler="IdUnselect"/>

            <Setter Property="Background"   Value="{Binding GoogleKeywordPositionMovementSinceLastWeekCheck, Converter={StaticResource NameToBrushConverter}}"/>
            <Setter Property="Content"      Value="{Binding Path=., Converter={StaticResource GooglePositionConvertor}}"/>

        </Style>
    </DataGridTextColumn.CellStyle>

</DataGridTextColumn>



public class GooglePositionConvertor : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        ResultCheckObject RankCheck = value as ResultCheckObject;

        return "hi";
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

通过以下方式通过转换器设置内容无效。

<Setter Property="Content" Value="{Binding Path=., Converter={StaticResource GooglePositionConvertor}}"/>

通过以下转换器进行设置

<DataGridTextColumn Width="60" Header="Google" Binding="{Binding Path=., Converter={StaticResource GooglePositionConvertor}}" CanUserResize="True" CanUserSort="True">

c＃wpf DataGridCell从convertor设置值
