Listview 前景色在选择模式下将保持不变

Question

我有以下XAML

但是我希望当用户框单击列表视图中的任何文本块时我希望文本的前景色保持不变（当前更改为白色）相反，我希望更改边框颜色我该怎么做？

ListView x:Name="LV" ItemsSource= "{Binding  Lggv}"     SelectionChanged="dataGridData_SelectionChanged" >
                <ListView.ItemTemplate>
                    <DataTemplate>
                        <StackPanel >
                            <Border BorderThickness="1" BorderBrush="Black">
                                <TextBlock Text="{Binding Info }" AllowDrop="True"  >
                                    <TextBlock.Background>
                                        <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">                                              
                                            <GradientStop Color="#FFCEE6C6" Offset="0.008"/>
                                            <GradientStop Color="#FF9ECF8C" Offset="0.987"/>
                                        </LinearGradientBrush>
                                    </TextBlock.Background>



                                </TextBlock>


                            </Border>

                                        <GradientStop Color="#FFC5DDFF" Offset="0"/>
                                        <GradientStop Color="#FFA8C8F7" Offset="1"/>
                                    </LinearGradientBrush>
                                </Grid.Background>
                                <Grid.ColumnDefinitions>

                                </Border>
                                <Border Grid.Column="1" BorderThickness="1" BorderBrush="Black">
                                    <TextBlock Text="{Binding ComPort}"></TextBlock>
                                </Border>

            </ListView>

您应该区分项目内容和项目容器。处理项目选择样式应该是容器的责任。以下样式定义了具有一些基本属性的 ListViewItem 的视觉表示的替代品。根据您想要的视觉效果，您可能需要定义不同的样式。

将样式定义为资源：

<Style x:Key="ListViewItemStyle" TargetType="ListViewItem">
    <Setter Property="Margin" Value="3"/>
    <Setter Property="Background" Value="Transparent"/>
    <Setter Property="BorderThickness" Value="1"/>
    <Setter Property="BorderBrush" Value="Transparent"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="ListViewItem">
                <Border
                    Background="{TemplateBinding Background}"
                    BorderBrush="{TemplateBinding BorderBrush}"
                    BorderThickness="{TemplateBinding BorderThickness}"
                    Padding="{TemplateBinding Padding}">
                    <ContentPresenter/>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
    <Style.Triggers>
        <Trigger Property="IsSelected" Value="True">
            <Setter Property="BorderBrush" Value="Red"/>
        </Trigger>
        <Trigger Property="IsMouseOver" Value="True">
            <Setter Property="Background" Value="LightBlue"/>
        </Trigger>
    </Style.Triggers>
</Style>

鼠标悬停（背景色）和选中（红色边框）时，项目显示不同。前景应该保持不变。

用法：

<ListView ItemContainerStyle="{StaticResource ListViewItemStyle}">
    <!-- your other code -->
</ListView>

Listview 前景色在选择模式下将保持不变
