ListView 选定项样式覆盖

Question

我有一个 WPF ListView，我也在尝试应用自定义样式...主要是我想让 listview 框的背景透明且没有边框...我想覆盖突出显示和选定的项目样式。默认高亮为半透明蓝色，选中项目为灰色。我想覆盖这些以自定义它们。我已经关注了几个线程和教程......包括这个one 但是，我的突出显示和选定的项目保持默认样式。这就是我所拥有的。

<UserControl.Resources>
    <ResourceDictionary>
        <Style x:Key="ListViewStyle" TargetType="ListView">
            <Setter Property="Background" Value="Transparent"></Setter>
            <Setter Property="BorderThickness" Value="0"></Setter>
            <Setter Property="BorderBrush" Value="Transparent"></Setter>
            <Style.Resources>
                <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Red" />
                <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Green" />
            </Style.Resources>
        </Style>
    </ResourceDictionary>
</UserControl.Resources>

....

<ListView Style="{StaticResource ListViewStyle}" ItemsSource="{Binding Path=Items}" ScrollViewer.VerticalScrollBarVisibility="Disabled" SelectedItem="{Binding Path=DataContext.Current" >
    <ListView.ItemTemplate>
        <DataTemplate DataType="local:Cases">
            <StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch">
                <!-- Some UI Controls Here  -->
            </StackPanel>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

这种尝试覆盖系统颜色的方法不适用于 Windows 8 及更高版本。

您需要修改ListViewItem容器的ControlTemplate。

您可以通过在 Visual Studio 或 Blend 中的设计模式下右键单击 ListView 并选择 Edit Additional Templates->Edit Generated Item Container (ItemContainerStyle) 将默认模板复制到 XAML 标记中，然后将其编辑为根据您的要求，例如更改SolidColorBrushes 的Color 属性：

<ListView ItemsSource="{Binding Path=Items}" SelectedItem="{Binding Path=DataContext.Current" >
    <ListView.Resources>
        <Style x:Key="FocusVisual">
            <Setter Property="Control.Template">
                <Setter.Value>
                    <ControlTemplate>
                        <Rectangle Margin="2" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
        <SolidColorBrush x:Key="Item.MouseOver.Background" Color="Red"/>
        <SolidColorBrush x:Key="Item.MouseOver.Border" Color="#a826A0Da"/>
        <SolidColorBrush x:Key="Item.SelectedInactive.Background" Color="#3DDADADA"/>
        <SolidColorBrush x:Key="Item.SelectedInactive.Border" Color="#FFDADADA"/>
        <SolidColorBrush x:Key="Item.SelectedActive.Background" Color="#3D26A0DA"/>
        <SolidColorBrush x:Key="Item.SelectedActive.Border" Color="#FF26A0DA"/>
        <Style TargetType="{x:Type ListViewItem}">

                            <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                        </Border>
