ListView ItemTemplate do not change heihgt based on content
When a ListView has a ItemTemplate with dynamic content, the ViewCell Height do now get resized consistently:
I have a sample where inside the ViewCell I have a gray block which I show/hide from code using a IsVisible Binding.
on android it works perfectly: when the block disappear, the card resizes itself and all items bellow reposition.
on UWP the block disappear but the card size stay the same until I change the size of the window. If I scroll down enough to hide the item and back again, it show with the right size.
on iOS, I get the same behavior as UWP, when the block disappear, the ViewCell height do not change until I scroll to hide it and scroll back.
Tested against 18.104.22.168-nightly and observed the contents of the cell collapse and expand when the box visibility is toggled, however the row itself doesn't resize.
I think this may be the correct behavior. Getting confirmation before closing the issue or reconfirming.
Frame and ContentView on UWP don't change (invalidate?) their size when children change.
Putting the contents of the ViewCell in a StackLayout instead of Frame resizes the entire row giving the expected behavior.
