Question

上下文：我使用Mahapps.Metro Flyouts和Material Design工具包。

问题：当Flyout打开时，它未按指定定位。例如，如果我将Flyout设置为Bottom的{{1}}，则它会定位在垂直中心。

我已经设置了App.xaml以支持Mahapps和Material Design。我还对主题和重音进行了映射，以获得一致的体验。

我采用了MD WIKI中显示的配置。我有一个Metro Window，我的应用程序使用Mahapps和Material Design样式的各种控件 - 没有任何麻烦。只有弹出窗口无法正常工作。

为了解决问题，我将应用程序降至最低。此外，我从Material Design Mahapps演示应用程序中获取了示例弹出窗口 虽然演示应用程序运行完美，但它在我的应用程序环境中不起作用。

如果我将Mahapps-MD兼容性内容从App.xaml中删除，则弹出按钮正常工作，但当然没有MD主题。

祝你好运，马库斯

使用Material Design Toolkit，Mahapps Metro Window中的Flyouts无法正常工作
