c＃wpf DataGridCell从转换器设置值

Question

I have this DataGridCell and it calls this converter. I was expecting the value of this cell to be "hi" (as I'm setting the cell "content" to "hi") when its shown in the datagrid after going through the convertor.

What am I doing wrong here?

<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();
    }
}

Setting the content through a converter in the way below did not work.

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

Setting it through a converter as below worked

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