ListBoxItem IsSelected样式

Question

我仍然没有得到它.你能否告诉我如何覆盖ListBox的默认行为.每次选择ListBoxItem时,都应更改Border的背景.不是整行的背景,而是仅指定边框的背景.

 <ListBox ItemsSource="{Binding Source={StaticResource AssetsViewSource}}">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <Border BorderThickness="2" BorderBrush="Black">
                    <StackPanel>
                        <TextBlock Text="Name: " />
                        <TextBlock Text="{Binding Name}" />
                    </StackPanel>
                </Border>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>

使用DataTemplate的Triggers集合和RelativeSource来获取包含ListBoxItem:

<DataTemplate>
  <Border BorderThickness="2" BorderBrush="Black" Name="Bd">
    <StackPanel>
      <TextBlock Text="Name: " />
      <TextBlock Text="{Binding Name}" />
    </StackPanel>
  </Border>
  <DataTemplate.Triggers>
    <DataTrigger Value="True"
                 Binding="{Binding 
                              IsSelected, 
                              RelativeSource={RelativeSource 
                                  AncestorType={x:Type ListBoxItem}}}">
      <!-- everybody loves HotPink -->
      <Setter TargetName="Bd" Property="Background" Value="HotPink"/>  
    </DataTrigger>
  </DataTemplate.Triggers>
</DataTemplate>
