WPF Datatrigger pour DataGrid en changeant seulement de l'ensemble de la ligne

J'ai un DataGrid avec un DataTrigger de l'installation, de sorte que lorsque sa valeur est "en HAUT", je voudrais le déclencheur à seulement un changement de fond dans la "directionColumn' datagridcolumn seulement.

Ce que j'ai obtenu jusqu'à présent les mises à jour de l'ensemble de la ligne. J'ai aussi essayé de placer 'targetname" dans le setter de l'élément, mais cela donne une erreur. S'il vous plaît aider.

XAML:

<DataGrid AutoGenerateColumns="False" ItemsSource="{Binding}" Name="summaryReportDataGridDATE" RowDetailsVisibilityMode="VisibleWhenSelected" Width="330">
    <DataGrid.CellStyle>
        <Style TargetType="DataGridCell">
            <Style.Triggers>
                <DataTrigger Binding="{Binding Path=Direction}" Value="UP">
                    <Setter>
                        <Setter.Property>Background</Setter.Property>
                        <Setter.Value>Red</Setter.Value>
                    <!--<Setter Property="Background" Value="Red" TargetName="directionColumn"/>-->
                    </Setter>
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </DataGrid.CellStyle>
    <DataGrid.Columns>
        <!--<DataGridTemplateColumn x:Name="dateColumn" Header="Date" Width="100" CanUserReorder="False" CanUserSort="False" FontFamily="Arial Rounded MT" >
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <DatePicker SelectedDate="{Binding Path=Date, Mode=OneWay}" />
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>-->

        <DataGridTextColumn x:Name="dateColumn" Binding="{Binding Path=Date, StringFormat={}{0:dd/MM/yyyy}}" Header="Date"  Width="80" CanUserReorder="False" CanUserSort="False" FontFamily="Arial Rounded MT"/>
        <DataGridTextColumn x:Name="closeColumn" Binding="{Binding Path=ClosingPrice}" Header="ClosingPrice" Width="80" CanUserReorder="False" CanUserSort="False" FontFamily="Arial Rounded MT" />
        <DataGridTextColumn x:Name="directionColumn" Binding="{Binding Path=Direction}" Header="Direction"  Width="80" CanUserReorder="False" CanUserSort="False" FontFamily="Arial Rounded MT" />
        <DataGridTextColumn x:Name="resultColumn" Binding="{Binding Path=Result}" Header="Result"  Width="80" CanUserReorder="False" CanUserSort="False" FontFamily="Arial Rounded MT"  />
    </DataGrid.Columns>
</DataGrid>

    Un TemplateColumn au lieu de cellule personnalisé style:

        <DataGrid AutoGenerateColumns="False" ItemsSource="{Binding}" Name="summaryReportDataGridDATE" RowDetailsVisibilityMode="VisibleWhenSelected" Width="330">                       
        <DataGrid.Columns>
            <DataGridTextColumn x:Name="dateColumn" Binding="{Binding Path=Date, StringFormat={}{0:dd/MM/yyyy}}" Header="Date"  Width="80" CanUserReorder="False" CanUserSort="False" FontFamily="Arial Rounded MT"/>
            <DataGridTextColumn x:Name="closeColumn" Binding="{Binding Path=ClosingPrice}" Header="ClosingPrice" Width="80" CanUserReorder="False" CanUserSort="False" FontFamily="Arial Rounded MT" />
            <DataGridTemplateColumn x:Name="directionColumn" Header="Direction"  Width="80" CanUserReorder="False" CanUserSort="False" >
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <TextBlock x:Name="directionColumnTextBlock" Text="{Binding Path=Direction}" Width="80" FontFamily="Arial Rounded MT"/>
                        <DataTemplate.Triggers>
                            <DataTrigger Binding="{Binding Path=Direction}" Value="UP">
                                <Setter TargetName="directionColumnTextBlock" Property="Background" Value="Red" />
                            </DataTrigger>
                        </DataTemplate.Triggers>
                    </DataTemplate>
                </DataGridTemplateColumn.CellTemplate>
            </DataGridTemplateColumn>                                                                              
            <DataGridTextColumn x:Name="resultColumn" Binding="{Binding Path=Result}" Header="Result"  Width="80" CanUserReorder="False" CanUserSort="False" FontFamily="Arial Rounded MT"  />
        </DataGrid.Columns>
    </DataGrid>
