  18.     /// <summary>  
  19.     /// Interaction logic for MainWindow.xaml  
  20.     /// </summary>  
  21.     public partial class MainWindow : Window  
  22.     {

  24.         {  
  25.             InitializeComponent();  
  26.         }  
  27.   
  28.         private void Window_Loaded(object sender, RoutedEventArgs e)  
  29.         {  
  30.             dgEmployee.ItemsSource = objEmployeeEntities.Employees.ToList();  
  31.         }  
  32.
