WPF：如何删除菜单项边框

所以我有一个简单的

菜单项

：

<ListView.ContextMenu>
    <ContextMenu Name="cmCopy">
        <MenuItem Style="{StaticResource MenuItemDefaultStyle}" Header="Copy" Click="MenuItem_Click"/>
    </ContextMenu>
</ListView.ContextMenu>

我真的想删除我的

MenuItem

周围的边框

尽管我给它下了定义：'

<Border BorderThickness="0" BorderBrush="Transparent" Background="{TemplateBinding Background}">

我仍然可以看到黑色的

边框

画笔

更新

MenuItem接收的不仅仅是您的模板

MenuItem根据其角色有两个模板

它可以是一片叶子。它可以是有孩子的父母。它可以是没有孩子的父母

正如你在这里看到的：

为了实现这一点，您需要修改所有这些选项。

米什卡是对的，它来自上下文菜单样式。这是一个默认样式，请查看其中的我的注释以获得所需内容

您的

样式中的
边框
是为弹出窗口指定的，而不是为
菜单项
指定的。那么我应该更改什么？在样式
中，这应该在
模板
标记上方。没有，这没有帮助，我仍然可以看到黑色边框。是否应用了您的样式？我的意思是：鼠标结束时文本是否会变成蓝色？
