WPF、XAML。 ListBoxItemトリガは選択全体に影響しませんか？ここ

Question

は私の問題だ：

<Style x:Key="listbox_minecraft_container_style" TargetType="{x:Type ListBoxItem}"> 
    <Setter Property="Background" Value="{DynamicResource image_listbox_item_background}"/> 
    <Setter Property="Margin" Value="1"/> 
    <Setter Property="BorderBrush" Value="#FF8B8B8B"/> 
    <Setter Property="BorderThickness" Value="0.4"/> 
    <Setter Property="HorizontalContentAlignment" Value="Center"/> 
    <Setter Property="Foreground" Value="Black"/> 
    <Setter Property="FontSize" Value="18"/> 
    <Setter Property="Width" Value="180"/> 
    <Setter Property="FontWeight" Value="SemiBold"/> 
    <Style.Triggers> 
     <Trigger Property="IsMouseOver" Value="True"> 
      <Setter Property="Foreground" Value="White"/> 
     </Trigger> 
     <Trigger Property="IsSelected" Value="True"> 
      <Setter Property="Background" Value="{DynamicResource image_listbox_item_background_fulopacity}"/> 
      <Setter Property="FontWeight" Value="Bold"/> 
      <Setter Property="Foreground" Value="#FF42A855"/> 
     </Trigger> 
    </Style.Triggers> 
</Style> 

私は今ListBoxItemをクリックすると、それが適切に設定された背景プロパティを取得できません。新しいForegroundと新しいFontWeightが設定されますが、Backgroundは設定されません。

<ListBox x:Name="listBox_vanilla_versions" 
     Style="{StaticResource listbox_minecraft}" 
     ItemContainerStyle="{StaticResource listbox_minecraft_container_style}" 
     Margin="10,122,484.592,198.5"> 
    <ListBox.Items> 
     <ListBoxItem Content="hi"/> 
    </ListBox.Items> 
</ListBox>

これが原因で、既定のコントロールテンプレートは次のとおりです。

は、これは私のListBoxMainWindowです。これを上書きする必要があります：

<Style x:Key="listbox_minecraft_container_style" TargetType="{x:Type ListBoxItem}"> 
    <Style.Resources>
