WPF。如果TextBlock中的文本等于ComboBox中的文本，则更改背景颜色TextBlock

Question

我有带有DeviceName的组合框。我在数据库中的DataGrid中有TextBlock和文本

<DataGrid>
...
<DataGridTemplateColumn Header="Device" Width="230">
...
    <Border BorderBrush="#FF757576" BorderThickness="0, 0, 0, 1">
        <StackPanel x:Name="StackPanelDevice" Orientation="Horizontal" >                                                
            <TextBlock  Text="{Binding Path=DeviceName}" HorizontalAlignment="Left" Width="200"/>
            <TextBlock  Text="{Binding Path=Count}" HorizontalAlignment="Right" Width="30" />
        </StackPanel>
   </Border>
...
</DataGridTemplateColumn>
</DataGrid>

我是这样做的：

<Border BorderBrush="#FF757576" BorderThickness="0, 0, 0, 1">
    <StackPanel x:Name="StackPanelDevice" Orientation="Horizontal" >
        <TextBlock  Text="{Binding Path=DeviceName}" HorizontalAlignment="Left" Width="200" >
            <TextBlock.Style>
                <Style>
                    <Style.Triggers>                                                               
                        <DataTrigger Value="True">
                            <DataTrigger.Binding>
                                <MultiBinding Converter="{StaticResource multiValueEqualityConverter}">
                                    <Binding  ElementName="ComboBoxModels" Path="SelectedValue"/>
                                    <Binding  Path="DeviceName"/>
                                </MultiBinding>
                            </DataTrigger.Binding>
                       <Setter Property="TextBlock.Background" Value="Red"/>
                   </DataTrigger>
               </Style.Triggers>
           </Style>
       </TextBlock.Style>      
    </TextBlock>
    <TextBlock  Text="{Binding Path=Count}" HorizontalAlignment="Right" Width="30" />
  </StackPanel>
 </Border>
