Question

我已经搜索了这个简单问题的答案，但还没有找到解决方案。我有以下代码：

<Grid>
    <Border BorderBrush="#666666" BorderThickness="1,1,1,1" CornerRadius="3">
        <Border.Background>
            <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                <GradientStop Color="#FF020f1e" Offset="0"/>
                <GradientStop Color="#FF484F58" Offset="1"/>
            </LinearGradientBrush>
        </Border.Background>
        <ListView Name="lvUsers" Background="Transparent" Foreground="White" Margin="3" FontSize="12" SelectionChanged="lvUsers_SelectionChanged">

            <ListView.Template>
                <ControlTemplate TargetType="{x:Type ListView}">
                    <Border CornerRadius="1" BorderThickness="1" BorderBrush="Transparent">
                        <ScrollViewer>
                            <ItemsPresenter />
                        </ScrollViewer>
                    </Border>
                </ControlTemplate>
            </ListView.Template>

            <ListView.View>
                <GridView>

                    <GridView.Columns>
                        <GridViewColumn>
                            <GridViewColumn.CellTemplate>
                                <DataTemplate>
                                    <CheckBox Tag="{Binding ID}" IsChecked="{Binding IsChecked}" Checked="CheckBox_CheckedChanged" Unchecked="CheckBox_CheckedChanged" IsHitTestVisible="False" Focusable="False"/>
                                </DataTemplate>
                            </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn DisplayMemberBinding="{Binding ID}" Header="ID" />
                        <GridViewColumn DisplayMemberBinding="{Binding Name}" Header="Name" />
                    </GridView.Columns>
                </GridView>                  
            </ListView.View>

            <ListView.ItemContainerStyle>
                <Style TargetType="ListViewItem">
                    <EventSetter Event="PreviewMouseLeftButtonDown" Handler="ListViewItem_PreviewMouseLeftButtonDown" />

                    <Style.Triggers>
                        <Trigger Property="IsMouseOver" Value="true">
                            <Setter Property="Background" Value="Transparent"/>

                        </Trigger>
                        <Trigger Property="IsSelected"  Value="true">
                            <Setter Property="Background" Value="Transparent"/>
                            <Setter Property="BorderBrush"  Value="Black"/>
                        </Trigger>

                    </Style.Triggers>
                </Style>
            </ListView.ItemContainerStyle>
        </ListView>
    </Border>
</Grid>

当我选择或＆＃34;鼠标悬停在＆＃34;之后会产生以下效果一排：

MyApplication

我想删除那个光泽效果并获得完全简单的样式＆＃34; ListView＆＃34;：

Target Application

你能告诉我实现这个的最简单方法吗？

非常感谢

ListViewItem在其模板（Controltemplate.Triggers）中有一些奇特的触发器，它们在某些条件下（例如，对于所选项目）更改背景。要删除它们，请设置一个简化的模板，不带触发器：

<Style TargetType="ListViewItem">
<Setter Property="Template">
    <Setter.Value>
        <ControlTemplate TargetType="{x:Type ListViewItem}">
            <Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" 
                    BorderThickness="{TemplateBinding BorderThickness}" 
                    Background="{TemplateBinding Background}" 
                    Padding="{TemplateBinding Padding}"
                    SnapsToDevicePixels="true">
                <GridViewRowPresenter 
                    HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" 
                    SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
                    VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
            </Border>
        </ControlTemplate>
    </Setter.Value>
</Setter>
<Style.Triggers> 
<!-- your triggers for IsMouseOver and IsSelected -->
</Style.Triggers>

您显然正在使用一些提供此效果的自定义样式。

您可以尝试将Style的{{1}}属性设置为ListView以使用默认样式：

{x:Null}

WPF从GridView的选择/鼠标移除光泽效果
