[UWP] [XAML]我自己实现CommandBar控件的问题 [英] [UWP][XAML] Problem with my own implementation of the CommandBar control

问题描述

您好，

我制作了一个自定义模板化控件，其行为与标准CommandBar控件非常相似。问题是，只要我点击我的CommandBar中包含的任何AppBarButton，就会发生未处理的异常：   " No
此类界面支持" ;.

I have made a custom templated control that behave much like the standard CommandBar control. The problem is that as soon as I click on any of the AppBarButton contained in my CommandBar, an unhandled exception occurs:   "No such interface supported".

有些事情我一定做错了但我却看不到。这是问题的一个小问题。

There is something I must doing wrong but I just can't see it. Here's a small repro of the problem.
