I changed the Rowdefinitions of the Root Grid to "Auto", but the Grid doesn't change its size, the inner Label gets correct the SizeChanged event. This looks like the same problem handled in #7297.
But even if I get the root grid change its size (in our program we use for instance an autosizing editor or a flex layout with dynamical content as Childs of the root grid in the Collectionview DataTemplate) the CollectionView doesn't update its cell.

I am facing the same issue. I tested a collectionview, where the IsVisible-attribute of some elements can be changed on a button press. Inside the collectionview is a grid, where some labels become visible/not visible. The labels push other content down on Android, as I intended. However, on iOS, it doesn't. There is no MaximumHeightRequest set, or something like that.

The project Maui.Controls.Sample in the Maui source solution contains a CollectionView sample named Expanding Text (Vertical List) with the same problem.

Verified this on Visual Studio Enterprise 17.8.0 Preview 2.0(8.0.0-rc.1). The original issue seems still repro on Windows 11 and iOS 16.4, not repro on Android 13.0-API33 with below Project:

It's been over half a year since this bug was initially reported.
This should be basic functionality that worked even in Xamarin Forms...

This can also be easily reproduced when using an expander in the ItemTemplate.

I'm having the same issue ...

Some people saying this is the native behaviors, but again, Xamarin Forms was working normally fine and MAUI break this, how can we suppose to migrate from Xamarin Forms to MAUI when we have a tons of CollectionView that we need to migrate and this isn't working normally ?!

The problem still exists for almost a year now. such things should be implemented out of the box, I already regret that I didn’t start using flutter for commercial development, it’s a complete disappointment.
