如何设置ScrollViewer或滚动(动态创建的网格)

这里我在表单上动态创建网格。代码工作得很好，但我希望这个网格在滚动查看器或滚动条(垂直)。谁能告诉我如何设置滚动在这个代码。

   Grid DynamicGrid = new Grid();            
        DynamicGrid.Width = 400;
        DynamicGrid.HorizontalAlignment = HorizontalAlignment.Right;
        DynamicGrid.VerticalAlignment = VerticalAlignment.Top;
        DynamicGrid.Margin = new Thickness(50);
        DynamicGrid.ShowGridLines = false;            
        DynamicGrid.Background = new SolidColorBrush(Colors.LightSteelBlue);
        // Create Columns
        ColumnDefinition gridCol1 = new ColumnDefinition();
        DynamicGrid.ColumnDefinitions.Add(gridCol1);

        // Create Rows
        RowDefinition gridRow1 = new RowDefinition();
        gridRow1.Height = new GridLength(30);
        DynamicGrid.RowDefinitions.Add(gridRow1);
        TextBlock txtBlock2 = new TextBlock();
        txtBlock2.Text = "Age";
        txtBlock2.FontSize = 14;
        txtBlock2.FontWeight = FontWeights.Bold;
        txtBlock2.Foreground = new SolidColorBrush(Colors.Green);
        txtBlock2.VerticalAlignment = VerticalAlignment.Top;
        Grid.SetRow(txtBlock2, 0);
        Grid.SetColumn(txtBlock2, 1);  
        TextBlock ageText = new TextBlock();
        ageText.Text = "33";
        ageText.FontSize = 12;
        ageText.FontWeight = FontWeights.Bold;
        Grid.SetRow(ageText, 1);
        Grid.SetColumn(ageText, 1);
        // Display grid into a Window
        window.Content = DynamicGrid;

ScrollViewer viewer = new ScrollViewer();
viewer.Content = DynamicGrid;
Window.Content = viewer;
