Answer 1

弹出窗口覆盖超过 75％的屏幕，首先减小其宽度，然后降低其高度，以达到75％的最大覆盖率限制。您无法覆盖使它全屏。

阅读文档：PlacementMode

Answer 2

after InitializeComponent in constructor, set popup child width and height from code

(popintaling.Child as FrameworkElement).Height = Window.Current.Bounds.Height;
(popintaling.Child as FrameworkElement).Width = Window.Current.Bounds.Width;

Answer 3

全屏弹出窗口不是弹出窗口。只需将该代码放入具有背景颜色的边框中，然后自己处理事件。另外，为了使您的应用程序全屏，只需将 WindowState 设置为最大化，将 WindowStyle 设置为无
