Completely Custom Context Menu
提问by Sarah
I am trying to create a completely custom context menu for a touch application with a radial style ("pie slices" for each item). I have been able to create one from with a base of ItemsControl. However, when I try to switch this to a base of ContextMenu, I cannot get rid of the default pop-up with each pie slice in a list of items.
我正在尝试为具有径向样式（每个项目的“饼图”）的触摸应用程序创建一个完全自定义的上下文菜单。我已经能够用 ItemsControl 的基础创建一个。但是，当我尝试将其切换到 ContextMenu 的基础时，我无法摆脱项目列表中每个饼图切片的默认弹出窗口。
Is there any way to override the default ContextMenu style to get rid of this items list functionality?
有没有办法覆盖默认的 ContextMenu 样式来摆脱这个项目列表功能？
Edit: This is a screen shot of my problem. The code is almost the exact same between the two examples, other than what class is inherited from and how it displays (adding as a child to a Canvas vs. showing the popup)
编辑：这是我的问题的屏幕截图。两个示例之间的代码几乎完全相同，除了从哪个类继承以及它如何显示（作为子项添加到 Canvas 与显示弹出窗口）
Edit 2: I tried overriding the default style as below:
编辑 2：我尝试覆盖默认样式，如下所示：
<ContextMenu.Style>
<Style TargetType="ContextMenu">
<Setter Property="OverridesDefaultStyle" Value="true" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ContextMenu">
<Canvas IsItemsHost="true" Height="100" Width="100" />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ContextMenu.Style>

If you just want to change appeareance of a WPF control, just change its controltemplate.
如果您只想更改 WPF 控件的外观，只需更改其控件模板。
Here is the default one for ContextMenu : http://msdn.microsoft.com/en-us/library/ms744758.aspx
这是 ContextMenu 的默认设置：http: //msdn.microsoft.com/en-us/library/ms744758.aspx
And do not forget to update the MenuItem controltemplate too : http://msdn.microsoft.com/en-us/library/ms747082(v=vs.85).aspx
并且不要忘记更新 MenuItem 控件模板：http: //msdn.microsoft.com/en-us/library/ms747082(v=vs.85) .aspx

I personaly don't know any way to override or change default contextmenu layout. If ever it appears that there is no proper way, I think you should create it from sratch using Adorner class, otherwise by creating a new transparent tomost window. Keep us informed of the solution you'll choose.
我个人不知道有什么方法可以覆盖或更改默认的上下文菜单布局。如果似乎没有正确的方法，我认为您应该使用 Adorner 类从 sratch 创建它，否则通过创建一个新的透明 tomost 窗口。让我们了解您将选择的解决方案。
