ListBox WPF:更改SelectedItem的前景色并保留Material Design

Question

如何在不从材料设计中删除样式的情况下更改SelectedItem的背景颜色？

这是有效的，但将从材料设计中删除样式：

<ListBox TextElement.Foreground="Black">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel IsItemsHost="True" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Style.Triggers>
<Trigger Property="IsSelected" Value="True" >
<Setter Property="FontWeight" Value="Bold" />
<Setter Property="Background" Value="Transparent" />
<Setter Property="Foreground" Value="White" />
</Trigger>
</Style.Triggers>
<Style.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent"/>
</Style.Resources>
</Style>
</ListBox.ItemContainerStyle>
</ListBox>

如何添加样式而不是替换样式？

Answer 1

将样式更改为BasedOn="｛StaticResource MaterialDesignListBoxItem｝">

<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem" BasedOn="{StaticResource MaterialDesignListBoxItem}">
<Style.Triggers>
<Trigger Property="IsSelected" Value="True" >
<Setter Property="FontWeight" Value="Bold" />
<Setter Property="Background" Value="Transparent" />
<Setter Property="Foreground" Value="White" />                               
</Trigger>
</Style.Triggers>
<Style.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent"/>
</Style.Resources>
</Style>
</ListBox.ItemContainerStyle>
