ListBoxItem中選擇顏色禁用，但內容過於

Question

關於前一個問題，我有以下的代碼，禁用藍色背景：

<ListBox Background="Transparent" BorderBrush="Transparent"> 
    <ListBox.Style> 
     <Style> 
      <Style.Resources> 
       <!-- Background of selected item when focussed --> 
       <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" /> 
       <!-- Background of selected item when not focussed --> 
       <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent" /> 
      </Style.Resources> 
     </Style> 
    </ListBox.Style> 
    <ItemsControl.ItemTemplate> 
     <DataTemplate> 
      <Border Margin="5" BorderThickness="2" BorderBrush="LightGray" CornerRadius="5"> 
       <Expander IsExpanded="True" Background="#f7f7f7"> 
        <!-- Content --> 
       </Expander> 
      </Border> 
     </DataTemplate> 
    </ItemsControl.ItemTemplate> 
</ListBox> 

什麼我注意到的是，現在一切事物都像組合框即在內容中也具有相同風格的透明選擇。我需要做什麼才能讓選擇對ListBoxItem唯一透明，而不是其內容？

您可以設置這些刷子的原始值在DataTemplate中，像這樣：

  <DataTemplate> 
       <DataTemplate.Resources> 
        <!-- Background of selected item when focussed --> 
        <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Blue" /> 
        <!-- Background of selected item when not focussed --> 
        <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Blue" /> 
       </DataTemplate.Resources> 
       <Border Margin="5" BorderThickness="2" BorderBrush="LightGray" CornerRadius="5"> 
        <Expander IsExpanded="True" Background="#f7f7f7"> 
         <!-- Content --> 

        </Expander> 
       </Border> 
      </DataTemplate>

你將不得不針對ListBoxItem並添加到ListBoxResources

<ListBox> 
    <ListBox.Resources> 
    <Style TargetType="{x:Type ListBoxItem}"> 
     <Style.Resources> 
      <!-- Background of selected item when focussed --> 
      <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" /> 
      <!-- Background of selected item when not focussed --> 
      <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent" /> 
     </Style.Resources> 
    </Style> 
    </ListBox.Resources> 
</ListBox>
