我有一个包含一些 ListViewItems 的 ListView。默认情况下，选择项目会使它们的背景变成深蓝色。我想应用一种样式，这样选择一个项目不会改变它的外观。

在我的 xaml 中我已经实现了这个:

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

不幸的是，这并不能解决问题。它只是简单地使选择变成白色而不是蓝色。

有没有人有想法？

祝你好运， 基督徒

编辑: 示例代码:

<Window.Resources>
    <Style TargetType="ListViewItem">
        <Style.Resources>
            <SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Black"/>                      
            <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent"/>
        </Style.Resources>
    </Style>
</Window.Resources>



<ListView x:Name="lvTestRun" ItemsSource="{Binding Path=TestRunData}" Margin="177,26,8,53.277" SelectionMode="Multiple">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Status"/>
            <GridViewColumn Header="Duration"/>
            <GridViewColumn Header="Start Time"/>
            <GridViewColumn Header="End Time"/>
        </GridView>
    </ListView.View>
</ListView>

为了重现这一点，您可能必须将单个 ListViewItem 的背景颜色设置为绿色或红色。

最佳答案

我不确定我是否理解您所说的白色而不是蓝色是什么意思。选择 ListViewItem 时，前景和背景将由触发器更改。要更改 ListViewItem 的前景，您可以使用此

<ListView ...>
    <ListView.ItemContainerStyle>
        <Style TargetType="{x:Type ListViewItem}">
            <Style.Resources>
                <!-- Foreground for Selected ListViewItem -->
                <SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" 
                                 Color="Black"/>
                <!-- Background for Selected ListViewItem -->
                <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}"
                                 Color="Transparent"/>
            </Style.Resources>
        </Style>
    </ListView.ItemContainerStyle>
    ...
</ListView>

更新

试试这个重新模板化。我删除了选定的所有触发器

<ListView ...>
    <ListView.ItemContainerStyle>
        <Style TargetType="{x:Type ListViewItem}">
            <Style.Resources>
                <LinearGradientBrush x:Key="ListItemHoverFill" EndPoint="0,1" StartPoint="0,0">
                    <GradientStop Color="#FFF1FBFF" Offset="0"/>
                    <GradientStop Color="#FFD5F1FE" Offset="1"/>
                </LinearGradientBrush>
            </Style.Resources>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type ListViewItem}">
                        <Border CornerRadius="2" SnapsToDevicePixels="True"  
                                BorderThickness="{TemplateBinding BorderThickness}"   
                                BorderBrush="{TemplateBinding BorderBrush}"   
                                Background="{TemplateBinding Background}">
                            <Border Name="InnerBorder" CornerRadius="1" BorderThickness="1">
                                <Grid>
                                    <Grid.RowDefinitions>
                                        <RowDefinition MaxHeight="11" />
                                        <RowDefinition />
                                    </Grid.RowDefinitions>

                                    <Rectangle Name="UpperHighlight" Visibility="Collapsed" Fill="#75FFFFFF" />
                                    <GridViewRowPresenter Grid.RowSpan="2"

                                            SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />
