CollectionView: [iOS] Scrolling issues with maui 9.0.30
I observe scrolling issues in the CollectionView on iOS when using Maui 9.0.30 version. 
For example the control has 25 items, I can scroll only to the first 10-11, cannot see the rest of the items.

Hi Zelin,

Lets continue the communication in the tickets you have opened.

The initial issue with the scrolling described here is fixed.

Hi Didi,

 

The scrolling issue is fixed, but I found two more problems:

  • SwipeView Actions Missing – Actions like delete and favorite in a list item no longer show up. I used the sample code from your docs.
  • CollectionView Doesn't Scroll on iOS – Setting ios:Page.UseSafeArea="True" on ContentPage makes the CollectionView unscrollable and stuck in place.

Do I need to log separate issues with you?

Thanks and regards,

Zelin

Testing the attached sample here - it appears the issue HAS been fixed.
There does, however, still seem to be an issue if the app is hosted in a TabView - our iOS RadCollectionView instances still can't scroll and this seems to be the only common denominator. Currently the only work-around is rolling back to 9.0.22 of Maui.Controls :(

yes we did. Updated to 9.0.40 and Telerik 10.0.0.
Scrolling is still frozen for iOS RadCollectionView.

@Nico @Didi - updated to 9.0.40. The issue remains :(
pinning to 9.0.22 is preventing us from getting a bunch of fixes - Telerik CollectionView is the only thing with the bug.
CollectionView works fine.
RadCollectionView does not :|

There will be ScrollView fixes in MAUI 9.0.31/9.0.40.
My suggestion: Try the latest MAUI Nightly to see if it solves the problem and Telerik doesn't have to take any action here

Hello Zelin,

Thank you for the project.

I understand this issue affects the app, still at this time I cannot share more details on this case.

There will be a research from our side to determine whether the issue is related to the improvements in the ScrollView introduced in maui 9.0.30 version. When there is more information, this will be addressed in the public item.

Didi

Hi Didi,

I have created the attached sample app using Telerik RadCollectionView code from the documentation to demonstrate the unscrollable issue. This problem is not reproducible when using .NET 9.0.22 and the corresponding NuGet packages.

Is there a way to prioritize this issue? Currently, our team is unable to downgrade the project, making our pages with RadCollectionView unusable. Additionally, I believe this issue is also causing RefreshView to break across all platforms.

Thanks and regards,

Zelin

Workaround:

1. Downgrade the project to 9.0.22 maui version

2. Clear the NuGet cache

3. Delete bin and obj folders from the project
