在列表視圖中選擇的項目設置樣式

Question

我有下面的XAML代碼：

<ListView.ItemTemplate> 
<DataTemplate> 
    <Border x:Name="SetBorder" Background="Transparent"> 
     <Grid Margin="5" Width="130"> 
      <Grid.RowDefinitions> 
       <RowDefinition Height="30"/> 
       <RowDefinition Height="Auto"/> 
      </Grid.RowDefinitions> 
      <Image Source="{Binding Path=Code, Converter={StaticResource SetCodeToImageConverter}}" MaxWidth="105"> 
       <Image.Style> 
        <Style> 
         <Style.Triggers> 
          <DataTrigger Binding="{Binding ElementName=SetBorder, Path=Selector.IsSelectionActive}" Value="True"> 
           <Setter Property="Image.Opacity" Value="1" /> 
          </DataTrigger> 
          <DataTrigger Binding="{Binding ElementName=SetBorder, Path=IsMouseOver}" Value="True"> 
           <Setter Property="Image.Opacity" Value="1" /> 
          </DataTrigger> 
          <DataTrigger Binding="{Binding ElementName=SetBorder, Path=IsMouseOver}" Value="False"> 
           <Setter Property="Image.Opacity" Value="0.5" /> 
          </DataTrigger> 
         </Style.Triggers> 
        </Style> 
       </Image.Style> 
      </Image> 
      <TextBlock Grid.Row="1" HorizontalAlignment="Center" VerticalAlignment="Center" 
         Text="{Binding Path=Name}" TextWrapping="WrapWithOverflow" MaxWidth="120"> 
      </TextBlock> 
     </Grid> 
    </Border> 
</DataTemplate> 

我想我的形象的不透明度設置爲1，當鼠標移動到（該部分作品）並選擇該項目時（該部分不起作用）。有任何想法嗎 ？

試試這個

<DataTrigger Binding="{Binding RelativeSource={RelativeSource AncestorType= {x:Type ListBoxItem}, Path=IsSelected}" Value="True"> 
    <Setter Property="Image.Opacity" Value="1" /> 
</DataTrigger> 

我還沒有嘗試過，但它應該工作
