CollectionView: [iOS] Scroll to last item scrolls to the first pixels of the last item

When scrolling to the last item using the ScrollITemIntoVIew() method to show the last item of a CollectionView, It doesn't scroll to the end of the list and only show the first pixels of the last item.

Hi Didi,

Apologies for the late response. I've encountered a similar issue in my project on iOS, where I cannot scroll the CollectionView. I used the sample code from the Telerik documentation and the setup was simple: ContentPage with a RadCollectionView. However, when I run the same code in a standalone app, the issue doesn't occur, which is quite confusing. I am currently trying to identify any differences between my project and the standalone app, as both use the latest nuget packages with the same setup.

Also, I noted this issue happened after updating the nuget packages to:

MauiVersion: 9.0.30
CommunityToolkitMauiVersion: 11.0.0

And I'm aware of recent changes in the collectionView (https://github.com/dotnet/maui/pull/26893/files) but as far as I know, these should not affect the Telerik CollectionView, correct?

Thanks and regards,

Zelin

Hello Zelin,

This is the option I can suggest for the behavior on iOS. On my side the workaround works as expected. The control scrolls to the end of the internal ScrollView.

Could you please share what is the exact setup you have and why the workaround does not work?

Hi Didi, I attempted the suggested workaround, but it didn't resolve the problem from my end.

Workaround:

Add the following to the page:

<ContentPage ............
xmlns:ios="clr-namespace:Microsoft.Maui.Controls.PlatformConfiguration.iOSSpecific;assembly=Microsoft.Maui.Controls"
ios:Page.UseSafeArea="True">
