ScrollBar.LineUpCommand Field


The command that scrolls a ScrollBar by a small amount in the vertical direction of decreasing value of its Track.

public: static initonly System::Windows::Input::RoutedCommand ^ LineUpCommand;
public static readonly System.Windows.Input.RoutedCommand LineUpCommand;
 staticval mutable LineUpCommand : System.Windows.Input.RoutedCommand
Public Shared ReadOnly LineUpCommand As RoutedCommand 

Field Value



The following example shows how to specify the LineUpCommand in a custom ScrollBar style template.

<RepeatButton Grid.Row="0" 
              Style="{DynamicResource Scrollbar_LineButton}" 
              Command="ScrollBar.LineUpCommand" Content=" ^" />


This command reduces the Value of the Track in the ScrollBar by the value of the SmallChange property.

This command occurs when the user presses the UP ARROW key.

When you implement a ScrollBar as part of a ScrollViewer control, the ScrollViewer executes this command.
