listview - 如何使运行时 ListView 具有绑定？wpf

Question

例如，我无法从此代码中获得结果！请帮助我，tnx。:)

        GridViewColumn gvc6 = new GridViewColumn();
        gvc6.DisplayMemberBinding = new Binding("sum");

        FrameworkElementFactory txt = new FrameworkElementFactory(typeof(TextBox));
        txt.SetBinding(TextBox.TextProperty, new Binding()); // sets binding


        gvc6.CellTemplate = new DataTemplate(typeof(string));
        gvc6.CellTemplate.VisualTree = txt;
