所以我想禁用将鼠标移到控件上时发生的IsMouseOver效果。这就是它的样子 https://i.imgur.com/P22YCLD.gifv

如何正确禁用它？

XAML

<Menu DockPanel.Dock="Top">
            <TabControl Background="DarkGray" BorderThickness="0" Height="150" Width="1273" Style="{DynamicResource TabControlStyle}">
                <TabControl.Resources>
                    <Style TargetType="TabItem">
                        <Setter Property="Template">
                            <Setter.Value>
                                <ControlTemplate TargetType="TabItem">
                                    <Border Name="Border" Margin="-2,0,0,-1" BorderThickness="0">
                                        <ContentPresenter x:Name="ContentSite"
                                                          VerticalAlignment="Center"
                                                          HorizontalAlignment="Center"
                                                          ContentSource="Header"
                                                          Margin="30,5"/>
                                    </Border>
                                    <ControlTemplate.Triggers>
                                        <Trigger Property="IsSelected" Value="True">

                                        <Trigger Property="IsSelected" Value="False">
                                            <Setter TargetName="Border" Property="Background" Value="#4f4f4f" />
                                            <Setter Property="Foreground" Value="White" />

您可以在Menu中覆盖MenuItem的默认模板以删除默认样式

       <Menu.Resources>
            <Style TargetType="{x:Type MenuItem}">
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="{x:Type MenuItem}">
                            <Border Background="{TemplateBinding Background}">
                                <ContentPresenter Content="{TemplateBinding Header}"/>
                            </Border>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
        </Menu.Resources>
