Question

I’ve got a ListViewItem that is added to a ListView, but I don’t know which ListView it is added to.

I would like to (through the ListViewItem) to be able to grab the ListView from the item itself.

I tried using the Parent property, but for some reason, it returns a StackPanel.

Any ideas?

I’ve gotten this to run and work:

private void Window_Loaded(object s, RoutedEventArgs args)
    {
        var collectionview = CollectionViewSource.GetDefaultView(this.listview.Items);
        collectionview.CollectionChanged += (sender, e) =>
        {
            if (e.NewItems != null && e.NewItems.Count > 0)
            {                   
                var added = e.NewItems[0];
                ListViewItem item = added as ListViewItem;
                ListView parent = FindParent<ListView>(item);
            }
        };

    }   
    public static T FindParent<T>(FrameworkElement element) where T : FrameworkElement
    {
        FrameworkElement parent = LogicalTreeHelper.GetParent(element) as FrameworkElement;

        while (parent != null)
        {
            T correctlyTyped = parent as T;
            if (correctlyTyped != null)
                return correctlyTyped;
            else
                return FindParent<T>(parent);
        }

        return null;
    }
