Question

I still didn t get it. Could you please show me exactly how to override ListBox s default behavior. Everytime when ListBoxItem is selected the Border s background should be changed. Not the background of the whole row but only background of the border which s specified.

 <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>

Answer 1

利用数据Template s Triggers Collection, with a RelativeSource to receive You to the contained 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>

Answer 2

简单地将以下内容列入清单Box项目标签

<ListBox.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" />
</ListBox.Resources>

这应当做到。
