自定義控件

 public class TreeListView : TreeView
    {
        static TreeListView()
        {
            DefaultStyleKeyProperty.OverrideMetadata(typeof(TreeListView), new FrameworkPropertyMetadata(typeof(TreeListView)));
        }

        public TreeListView()
        {
            Columns = new GridViewColumnCollection();
        }

        public static readonly DependencyProperty ColumnsProperty = DependencyProperty.Register("Columns", typeof(GridViewColumnCollection), typeof(TreeListView), new UIPropertyMetadata(null));
        public GridViewColumnCollection Columns
        {
            get { return (GridViewColumnCollection)GetValue(ColumnsProperty); }
            set { SetValue(ColumnsProperty, value); }
        }
    }
