'Declaration
Public Enumeration ScrollBarVisibility
'Usage
Dim instance As ScrollBarVisibility

public enum ScrollBarVisibility
public enum ScrollBarVisibility
<object property="EnumerationValue" .../>

 Member nameDescription
AutoA ScrollBar appears and the dimension of the ScrollViewer is applied to the content when the viewport cannot display all of the content. For a horizontal ScrollBar, the width of the content is set to the ViewportWidth of the ScrollViewer. For a vertical ScrollBar, the height of the content is set to the ViewportHeight of the ScrollViewer
DisabledA ScrollBar does not appear even when the viewport cannot display all of the content. The dimension of the content is set to the corresponding dimension of the ScrollViewer parent. For a horizontal ScrollBar, the width of the content is set to the ViewportWidth of the ScrollViewer. For a vertical ScrollBar, the height of the content is set to the ViewportHeight of the ScrollViewer
HiddenA ScrollBar does not appear even when the viewport cannot display all of the content. The dimension of the ScrollViewer is not applied to the content. 
VisibleA ScrollBar always appears. The dimension of the ScrollViewer is applied to the content. For a horizontal ScrollBar, the width of the content is set to the ViewportWidth of the ScrollViewer. For a vertical ScrollBar, the height of the content is set to the ViewportHeight of the ScrollViewer

Use this enumeration to set the HorizontalScrollBarVisibility and VerticalScrollBarVisibility property values of the ScrollViewer control.

The member values of this enumeration specify ScrollBar visibility in a given direction. These member values also specify whether the corresponding ScrollViewer dimension is applied to its enclosed content.

When you apply the ViewportWidth or ViewportHeight to ScrollViewer content, you set the viewport size for the content.

The following example shows how to use the member values of this enumeration to set the HorizontalScrollBarVisibility property of the ScrollViewer control.


'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
