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.

Release 10.1.0
Steps to Reproduce

1. Create a RadCollectionView with an ObservableCollection<ButtonModel> as the ItemsSource.

2. Use a DataTemplate inside RadCollectionView.ItemTemplate to display buttons.

3. Bind button properties (IsOddClick, IsEvenClick) that should change on click.

4. Click the button inside the RadCollectionView and observe that:

5. The text updates correctly, but part of it is cut off. It seems the text does not expand

Hi Team,

Please consider adding a way to cancel a group's expand/collapse action when the user taps on the group header.

For example, through a GroupTapping event handler that fires just before GroupTapped, and we can execute logic that prevents the operation:

private void RadCollectionView_OnGroupTapping(object sender, RadTappingEventArgs<GroupContext> e)
{
    if (e.Data.Key.ToString() == "GroupToStayPermanentlyExpanded")
    {
        e.Cancel();
    }
}


// which uses this imaginary event args with Cancel method
public class RadTappingEventArgs<T>(T data) : RadTappedEventArgs<T>(data)
{
    public void Cancel()
    {
        // prevents GroupTapped event
    }
}

Thank you,

Rodrigo

1. Bind the CheckedItems collection of the TreeView to the CollectionView ItemsSource.

2. there aren't any items in the TreeView initially.  Add items to it

3. Start checking the checkboxes

4. The items are added to the CollectionView, still they are not visible in the control.

When removing items from the collection's item source, the group header item count does not update real time. It only updates when the GroupContext is collapsed or expanded. This would also be an issue if items are added dynamically.

There is a memory leak in the CollectionView on iOS/MacCatalyst - when the CollectionView control is on the page, the page does not dispose when GC runs. Same behavior happens with the RadListview.

I have a CollectionView that is populated when tapping on an item from another CollectionView. I am using the Add method to add the items to the CollectionView. But the items are duplicated (they are added two times).
