Une piste poignées seulement le positionnement du pouce et les boutons de répétition link text. L'apparence réelle de la piste est dans le modèle du curseur.

Pour changer l'apparence du changement la zone suivante "piste", PART_SelectionRange, dans le modèle de contrôle

<ControlTemplate TargetType="{x:Type Slider}"> 
<Border SnapsToDevicePixels="true" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}"> 
    <Grid> 
     <Grid.RowDefinitions> 
      <RowDefinition Height="Auto"/> 
      <RowDefinition Height="Auto" MinHeight="{TemplateBinding MinHeight}"/> 
      <RowDefinition Height="Auto"/> 
     </Grid.RowDefinitions> 
     <TickBar x:Name="TopTick" Height="4" Visibility="Collapsed" Grid.Row="0" Fill="{TemplateBinding Foreground}" Placement="Top"/> 
     <TickBar x:Name="BottomTick" Height="4" Visibility="Collapsed" Grid.Row="2" Fill="{TemplateBinding Foreground}" Placement="Bottom"/> 
     <Border Margin="5,0" VerticalAlignment="center" Height="20.0" Grid.Row="1" Background="{StaticResource HorizontalSliderTrackNormalBackground}" BorderBrush="{StaticResource HorizontalSliderTrackNormalBorder}" BorderThickness="1" CornerRadius="1"> 
      <Canvas Margin="-6,-1"> 
       <Rectangle x:Name="PART_SelectionRange" Fill="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}" Stroke="{DynamicResource {x:Static SystemColors.ControlDarkDarkBrushKey}}" StrokeThickness="1.0" Height="4.0" Visibility="visible"/> 
      </Canvas> 
     </Border> 
     <Track x:Name="PART_Track" Grid.Row="1"> 
      <Track.DecreaseRepeatButton> 
       <RepeatButton Style="{StaticResource SliderRepeatButtonStyle}" Command="{x:Static Slider.DecreaseLarge}"/> 
      </Track.DecreaseRepeatButton> 
      <Track.IncreaseRepeatButton> 
       <RepeatButton Style="{StaticResource SliderRepeatButtonStyle}" Command="{x:Static Slider.IncreaseLarge}"/> 
      </Track.IncreaseRepeatButton> 
      <Track.Thumb> 
       <Thumb x:Name="Thumb" Style="{StaticResource HorizontalSliderThumbStyle}"/> 
      </Track.Thumb> 
     </Track> 
    </Grid> 
</Border>
