Question

我是WPF的新手，并尝试着手定制UI元素。

第一个问题：

我正在尝试为MenuItems的所有状态自定义背景和前景色（和边框），我似乎无法找到需要更改的所有属性。我已成功更改了所有颜色，但有一个例外：当菜单打开时，子菜单项周围有一个灰色框，我无法弄清楚如何更改灰色框的属性。

详细信息：

我在这里和其他地方阅读了很多帖子，似乎很清楚我需要为菜单项创建一个控件模板。经过多次尝试从头开始，我决定使用VS创建默认模板的副本（MenuItem属性 - ＆gt;转换为新资源）。

使用该模板解决了我的大多数问题，但有一个例外，子菜单项周围有一个灰色框，如下所示：image of open menu

有人能告诉我如何更改灰盒子的颜色吗？

第二个问题：

虽然模板解决了我的大部分问题，但它似乎又创造了另一个问题。当我配置菜单项以使用模板时，我看到UI中的视觉更改，但菜单项在单击时停止打开子菜单。 Click事件仍然会触发，后面的代码中的事件处理程序工作正常，它只是打开并显示其中的菜单项。

任何帮助将不胜感激。我希望我只是遗漏了一些简单的东西。我已经看到了一些控制定制的相当棘手的例子。我希望我不需要走那么远只是为了改变鼠标悬停时的背景颜色。

感谢。

这是现在的模板。
