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

This command decreases the Value of the Track in the ScrollBar by the value of the LargeChange property.

The different parts of a ScrollBar

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

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


<Style x:Key="ScrollBar_LeftTrack" 
       BasedOn="{StaticResource ScrollBar_TrackRepeater}" 
       TargetType="{x:Type RepeatButton}">
