WPF ListBox关闭悬停效果 [英] WPF ListBox turn off hover effect

问题描述

我已经在互联网上找到并尝试了许多解决方案，这些解决方案应该允许我禁用WPF ListBox的悬停效果，但是似乎没有一个对我有用。此屏幕快照显示了我想隐藏或摆脱的悬停效果：

I've found and tried many solutions on the internet which should allow me to disable the hover effect of my WPF ListBox but none of them seemed to work for me. This screenshot shows the hover effect I'd like to hide or get rid of:

这是我当前拥有的XAML代码的（简化版本）：

This is (a simplified version) of the XAML code I currently have:

<ListBox ItemsSource="{Binding Logs}" Grid.Column="1" Width="800"  Height="100" >
    <ListBox.ItemContainerStyle>
        <Style TargetType="ListBoxItem">
            <Style.Triggers>
                <Trigger Property="Control.IsMouseOver" Value="True">
                    <Setter Property="Control.Background" Value="Transparent" />
                </Trigger>
            </Style.Triggers>
        </Style>
    </ListBox.ItemContainerStyle>
</ListBox>

但是，由于某种原因，它似乎对我没有用。我的父级ListBox（背景中的一个）或另一个控件是否可以覆盖其孩子的样式？ （我已经尝试过覆盖父样式）

However, it doesn't seem to work for me for a reason or another. Could my parent ListBox (the one in the background) or another control override it's child's style by any chance? (I already tried to override the parents style as well)

推荐答案

修改ListBoxItem的默认样式

Modify the default style of a ListBoxItem

<Style TargetType="{x:Type ListBoxItem}">
        <Setter Property="Background" Value="Transparent"/>
        <Setter Property="HorizontalContentAlignment" Value="{Binding HorizontalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}"/>
        <Setter Property="VerticalContentAlignment" Value="{Binding VerticalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}"/>
        <Setter Property="Padding" Value="2,0,0,0"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ListBoxItem}">
                    <Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="true">
                        <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsSelected" Value="true">
                            <Setter Property="Background" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
                            <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.HighlightTextBrushKey}}"/>
                        </Trigger>
                        <MultiTrigger>
                            <MultiTrigger.Conditions>
                                <Condition Property="IsSelected" Value="true"/>
                                <Condition Property="Selector.IsSelectionActive" Value="false"/>
                            </MultiTrigger.Conditions>
                            <Setter Property="Background" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.InactiveSelectionHighlightBrushKey}}"/>
                            <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.InactiveSelectionHighlightTextBrushKey}}"/>
                        </MultiTrigger>
                        <Trigger Property="IsEnabled" Value="false">
                            <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

只需添加触发器

<Trigger Property="IsMouseOver" Value="True">
                            <Setter Property="Background" Value="Transparent"/>
                        </Trigger>
