↑を参考にやってみたら、うまくいった。
よかった。

    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            TextBox txtNumber = new TextBox();
            txtNumber.Name = "txtNumber";
            txtNumber.Text = "1776";
            txtNumber.Height = 20;
            txtNumber.Width = 100;
            testGrid.Children.Add(txtNumber);
            testGrid.RegisterName(txtNumber.Name, txtNumber);
        }

    }
