Closed ryanalford-suzy closed 4 months ago

ryanalford-suzy commented 4 months ago

Description

On iOS, programmatically changing the Position of the CarouselView no longer works if you navigate away and come back when using Shell navigation.

Android works fine.

EDITED: Tested using NavigationPage instead of Shell navigation, and the issue still exists.

Steps to Reproduce

  1. Run the project
  2. Tap the bottom buttons to see the CarouselView switch between fragments.
  3. Tap the Open Second Page button
  4. Tap the Back button at the top left.
  5. Tap the bottom buttons again.

@RoiChen001 were you able to confirm if this works on 8.0.40 and regressed in later versions?

ryanalford-suzy commented 4 months ago

I've added a second branch in the sample repo that targets 8.0.40.

Make sure to delete bin/obj folders when switching maui versions.

@PureWeen Yes, it works fine at iOS platform on 17.11.0 Preview 2.1(8.0.40).
