WPF Side Menu и динамически отображаемые элементы

Question

Я создаю окно WPF с боковым меню. Когда пользователь нажимает на один из элементов бокового меню, я хочу отображать определенные текстовые поля, выпадающие меню, кнопки. Они будут различаться в зависимости от того, какое меню нажата.

Должен ли я определять все возможные элементы в xaml или эти элементы могут быть построены, а события обрабатываются динамически на C#?

Answer 1

Я выяснил, как кодировать и отображать различные сетки. Теперь я не могу понять, как получить значения из моих элементов управления в сетке. Мой код:

частная пустота MenuItem_Click (объект отправителя, RoutedEventArgs е) { // * Меню базы данных Нажмите *

 grdExcel.Visibility = Visibility.Hidden; 
     grdDatabase.Visibility = Visibility.Visible; 
     //grdDataScrubber.Children.Remove(grdExcel); 

     // ... Cast sender object. 
     MenuItem item = sender as MenuItem; 
     // ... Change Title of this window. 
     Title = "Process " + item.Header + " Files"; 


     //InitializeGrid(grdDatabase, item); 
     //AddDatabaseControls(); 
     //grdDataScrubber.Children.Add(grdDatabase); 
    } 

    private void MenuItem_Click_1(object sender, RoutedEventArgs e) 
    { 
     //*** Excel Menu Click *** 
     Label lblExcelInfo = new Label(); 

     grdDatabase.Visibility = Visibility.Hidden; 
     grdExcel.Visibility = Visibility.Visible; 
     //grdDataScrubber.Children.Remove(grdDatabase); 

     // ... Cast sender object. 
     MenuItem item = sender as MenuItem; 
     // ... Change Title of this window. 
     Title = "Process " + item.Header + " Files"; 

     //InitializeGrid(grdExcel); 
     //lblExcelInfo.Content = "In Excel"; 
     //grdExcel.Children.Add(lblExcelInfo); 
     //grdDataScrubber.Children.Add(grdExcel); 
    } 


    private void InitializeGrid(Grid gridArea) 
    { 
     gridArea.Height = 330; 
     gridArea.Width = 650; 
     gridArea.HorizontalAlignment = HorizontalAlignment.Left; 
     gridArea.Margin = new Thickness 
     { 
      Bottom = 0, 
      Left = 70, 
      Top = 0, 
      Right = 0 
     }; 
     gridArea.VerticalAlignment = VerticalAlignment.Top; 
     //gridArea.Background = new SolidColorBrush(Color.FromRgb(04, 149, 168)); 

     grdDataScrubber.Children.Add(gridArea); 
    }
