C# retrieve ListView Items from ItemsSource

Question

I am trying to retrieve the Items from my nested ListView from a tap gesture.

private void TapGestureRecognizer_Tapped(object sender, EventArgs e)
        {
            var source = ItemsCollectionView.ItemsSource as ObservableCollection<TableDataGroupDel>;
            Debug.WriteLine("Items count: " + (source[0].Items as ObservableCollection<TableDataItemDel>).Count);
        }

This is my constructor:

public class TableDataGroupDel : ObservableCollection<TableDataItemDel>
        {
            public TableDataGroupDel(string rayon, ObservableCollection<TableDataItemDel> animals) : base(animals)
            {
                this.Rayon = rayon;
                this.Items = new ObservableCollection<TableDataItemDel>();
            }

            public string Rayon { get; private set; }

            public new ObservableCollection<TableDataItemDel> Items { get; set; }
        }

I am casting it to ObservableCollection<TableDataItemDel> but it doesn't seem to work. A source.Count gives me a value of 1 which means my List isn't empty and I can even get the Rayon out of it. I can't seem to be able to get the Items and I can't work it out why? Any help is appreciated.

Edit: I can access the Items throu .SelectedItem
