如何正确设置WPF上下文菜单的样式？ [英] How do I style a WPF context menu correctly?

问题描述

我花了好几天时间尝试设置TextBox的ContextMenu样式，但无法在任何有用的解决方案附近使用。出于某种原因，在应用MenuItem的某些部分时，ContextMenu从未应用于TextBox - 请参阅链接页面上的屏幕截图。



奇怪的是ContextMenu是在主窗口文本编辑器中设置好，但不在文本框中，如下面的链接页面所示。有人知道我在这里做错了吗？

I have literally spent days trying to style the ContextMenu of a TextBox but cannot get anywhere near a useful solution. For some reason is the ContextMenu never applied to a TextBox while some parts of the MenuItem are applied - see screenshots on linked page.

The strange thing is that the ContextMenu is styled OK in the Main Window Text Editor but not in the textbox as shown in the linked page below. Does someone have an idea what I am doing wrong here?

What I have tried:

Tried to re-style the ContextMenu (changed background color or Border Color) to see whats wrong but it does not seem to have an effect so I am wondering how this is implemented correctly...
