如何从ListViewItem获取ListView？

Question

我有一个ListViewItem添加到ListView,但我不知道它添加到哪个ListView.

我想(通过ListViewItem)能够从项目本身获取ListView.

我尝试使用Parent属性,但由于某种原因,它返回一个StackPanel.

有任何想法吗？

我已经让它运行和工作:

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;
    }
