Windows.Graphics.Display.DisplayInformation.OrientationChanged
May 17, 2019 ยท View on GitHub
-description
Occurs when either the CurrentOrientation or NativeOrientation property changes because of a mode change or a monitor change.
-remarks
The OrientationChanged event occurs only when orientation of the display or monitor changes and not necessarily when the orientation of your app changes. To determine the orientation of your app for layout purposes, use the ApplicationView.Value property.
