C# XAML通过XAML用户控件和绑定标记调用网格cs元素

有一个现有的代码，我已经得到，但这是一个动态链接库和工程与第三方应用程序。我想独立运行它，看看它是如何工作的，所以我在cs编码端创建了一个网格，并从xaml调用该网格。我试过几种方法，但我只是提供了下面的例子。我根本无法运行它。感谢您的帮助

PS：我需要保持UserControl和Binding标记的原样。

嗨，我想出了这个，它可以作为任何需要它的人的一个例子

类别：

 Grid customGrid = new Grid();
        public MainWindow(){

            InitializeComponent();          

            var tb = new TextBlock();
            tb.Text = "sdasdadsas1";
            customGrid.Children.Add(tb);

            tb = new TextBlock();
            tb.Text = "sdassssdas2";
            customGrid.Children.Add(tb);

            tb = new TextBlock();
            tb.Text = "sdasdas3";
            customGrid.Children.Add(tb);

            this.DataContext = this;

        }

        public Grid gridTest
        {
            get { return customGrid; }
            set { customGrid = value; }
        }

初始化组件；也在主窗口构造函数中调用。忘了放在那儿了。代码经过简化，便于阅读。谢谢。

<Grid Grid.Column="1" Grid.Row="2" HorizontalAlignment="Center" 
      VerticalAlignment="Top">
    <UserControl Grid.Row="3" HorizontalAlignment="Center"
                 VerticalAlignment="Top">
        <Binding>
            <Binding.Path>customGrid</Binding.Path>
        </Binding>
    </UserControl>
</Grid>

 Grid customGrid = new Grid();
        public MainWindow(){

            InitializeComponent();          

            var tb = new TextBlock();
            tb.Text = "sdasdadsas1";
            customGrid.Children.Add(tb);

            tb = new TextBlock();
            tb.Text = "sdassssdas2";
            customGrid.Children.Add(tb);

            tb = new TextBlock();
            tb.Text = "sdasdas3";
            customGrid.Children.Add(tb);

            this.DataContext = this;

        }

        public Grid gridTest
        {
            get { return customGrid; }
            set { customGrid = value; }
        }

   <UserControl Grid.Row="3" >
        <Binding>
            <Binding.Path>gridTest</Binding.Path>
        </Binding>
    </UserControl>
