網格線不會顯示

Question

網格線不會顯示在runt-time我可以看到我要去哪裏錯了。這是一個WPF窗口應用程序。我只想使用C＃代碼生成列和行。任何想法爲什麼這不起作用？

 using System; 
     using System.Collections.Generic; 
     using System.Linq; 
     using System.Text; 
     using System.Windows; 
     using System.Windows.Controls; 
     using System.Windows.Data; 
     using System.Windows.Documents; 
     using System.Windows.Input; 
     using System.Windows.Media; 
     using System.Windows.Media.Imaging; 
     using System.Windows.Navigation; 
     using System.Windows.Shapes; 

     namespace generator 
     { 
/// <summary> 
/// Interaction logic for MainWindow.xaml 
/// </summary> 
public partial class MainWindow : Window 
{ 
    public MainWindow() 
    { 
     InitializeComponent(); 

    } 

    private void CreateGrid() 
    { 

     ColumnDefinition myColum =new ColumnDefinition(); 
     RowDefinition myRow = new RowDefinition(); 
     ColumnDefinition myColum1 = new ColumnDefinition(); 
     RowDefinition myRow1 = new RowDefinition(); 

     Grid myGrid = new Grid(); 
     myRow.Height = new GridLength(1, GridUnitType.Star); 
     myColum.Width = new GridLength(1, GridUnitType.Star); 
     myRow1.Height = new GridLength(1, GridUnitType.Star); 
     myColum1.Width = new GridLength(1, GridUnitType.Star); 

     myGrid.ColumnDefinitions.Add(myColum); 
     myGrid.RowDefinitions.Add(myRow); 
     myGrid.ColumnDefinitions.Add(myColum1); 
     myGrid.RowDefinitions.Add(myRow1); 
     myGrid.ShowGridLines = true; 

    } 

    private void Window_Loaded(object sender, RoutedEventArgs e) 
    { 
     CreateGrid(); 
    } 

} 

}

問題不妨讀 「網格將不顯示」。

您正在創建一個新的Grid實例，但您絕不會將其添加到可視化樹中。你可以把它分配給窗口的Content屬性：

private void CreateGrid() 
{ 
    ... 
    Content = myGrid; 
}
