Gewusst wie: Erstellen eines ScrollViewer
Aktualisiert: November 2007
In diesem Beispiel wird das Erstellen und Verwenden eines ScrollViewer-Elements in Extensible Application Markup Language (XAML) veranschaulicht.
Im folgenden Beispiel wird ein Fenster erstellt, das etwas Text und ein Rechteck enthält. Die Bildlaufleisten werden nur bei Bedarf angezeigt. Die Bildlaufleisten werden beim Ändern der Größe des Fensters ein- oder ausgeblendet.
Das vollständige Beispiel finden Sie unter Beispiel zu ScrollViewer.
Beispiel
'Define a ScrollViewer.
Dim myScrollViewer As New ScrollViewer
myScrollViewer.HorizontalScrollBarVisibility = ScrollBarVisibility.Auto
'Add Layout control.
Dim myStackPanel As New StackPanel
myStackPanel.HorizontalAlignment = System.Windows.HorizontalAlignment.Left
myStackPanel.VerticalAlignment = System.Windows.VerticalAlignment.Top
Dim myTextBlock As New TextBlock
myTextBlock.TextWrapping = TextWrapping.Wrap
myTextBlock.Margin = New Thickness(0, 0, 0, 20)
myTextBlock.Text = "Scrolling is enabled when it is necessary. Resize the Window, making it larger and smaller."
Dim myRectangle As New Rectangle
myRectangle.Fill = Brushes.Red
myRectangle.Width = 500
myRectangle.Height = 500
'Add child elements to the parent StackPanel.
myStackPanel.Children.Add(myTextBlock)
myStackPanel.Children.Add(myRectangle)
'Add the StackPanel as the lone Child of the Border
myScrollViewer.Content = myStackPanel
Me.Content = myScrollViewer
// Create the application's main window
mainWindow = new Window ();
mainWindow.Title = "ScrollViewer Sample";
// Define a ScrollViewer
myScrollViewer = new ScrollViewer();
myScrollViewer.HorizontalScrollBarVisibility = ScrollBarVisibility.Auto;
// Add Layout control
myStackPanel = new StackPanel();
myStackPanel.HorizontalAlignment = HorizontalAlignment.Left;
myStackPanel.VerticalAlignment = VerticalAlignment.Top;
TextBlock myTextBlock = new TextBlock();
myTextBlock.TextWrapping = TextWrapping.Wrap;
myTextBlock.Margin = new Thickness(0, 0, 0, 20);
myTextBlock.Text = "Scrolling is enabled when it is necessary. Resize the Window, making it larger and smaller.";
Rectangle myRectangle = new Rectangle();

// Add the StackPanel as the lone Child of the Border
myScrollViewer.Content = myStackPanel;
// Add the Border as the Content of the Parent Window Object
