How to: Create a ScrollViewer

This example shows how to create and use a ScrollViewer element in Extensible Application Markup Language (XAML).

The following example creates a window that contains some text and a rectangle. The scroll bars appear only when they are needed. When you resize the window, the scroll bars appear and disappear.

For the complete sample, see ScrollViewer Sample.

Example

'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();
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;

// Add the Border as the Content of the Parent Window Object
mainWindow.Content = myScrollViewer;
mainWindow.Show ();

// Create the application's main window
mainWindow = gcnew System::Windows::Window();
mainWindow->Title = "ScrollViewer Sample";

// Define a ScrollViewer
myScrollViewer = gcnew ScrollViewer();
myScrollViewer->HorizontalScrollBarVisibility = ScrollBarVisibility::Auto;

// Add Layout control
