NativeControlHost Content Not Displaying After Page Transition in TransitioningContentControl on Windows #14747

Open LITTOMA opened 9 months ago

LITTOMA commented 9 months ago

Describe the bug

On the Windows platform, when using NativeControlHost inside TransitioningContentControl, the content within NativeControlHost does not display after the TransitioningContentControl switches pages. The content becomes visible only after the user manually resizes the window. Debugging reveals that the native control's position is initially set to an incorrect X coordinate, which corrects itself upon window resize, suggesting an issue with native control positioning after a page transition.

To Reproduce

Steps to reproduce the behavior:

  1. Implement TransitioningContentControl with a NativeControlHost embedded.
  2. Trigger a page transition within TransitioningContentControl.
  3. Observe that the content inside NativeControlHost does not display after the transition.
  4. Manually resize the window to see the previously invisible content appear.

Expected behavior

After a page transition in TransitioningContentControl, the content within NativeControlHost should display correctly without requiring a manual window resize.
