ScrollBar.LineDownCommand Field


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

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

Field Value



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

<RepeatButton Grid.Row="2" 
              Style="{DynamicResource Scrollbar_LineButton}" 
              Command="ScrollBar.LineDownCommand" Content=" v" />


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

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

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