# ScrollBar Styles and Templates
This topic describes the styles and templates for the <xref:System.Windows.Controls.Primitives.ScrollBar> control. You can modify the default <xref:System.Windows.Controls.ControlTemplate> to give the control a unique appearance. For more information, see [Create a template for a control](how-to-create-apply-template.md).
## ScrollBar Parts
The following table lists the named parts for the <xref:System.Windows.Controls.Primitives.ScrollBar> control.
|Part|Type|Description|
|-|-|-|
|PART_Track|<xref:System.Windows.Controls.Primitives.Track>|The container for the element that indicates the position of the <xref:System.Windows.Controls.Primitives.ScrollBar>.|
## ScrollBar States
The following table lists the visual states for the <xref:System.Windows.Controls.Primitives.ScrollBar> control.
|VisualState Name|VisualStateGroup Name|Description|
|----------------------|---------------------------|-----------------|
|Normal|CommonStates|The default state.|
|MouseOver|CommonStates|The mouse pointer is positioned over the control.|
|Disabled|CommonStates|The control is disabled.|
|Valid|ValidationStates|The control uses the <xref:System.Windows.Controls.Validation> class and the <xref:System.Windows.Controls.Validation.HasError%2A?displayProperty=nameWithType> attached property is `false`.|
|InvalidFocused|ValidationStates|The <xref:System.Windows.Controls.Validation.HasError%2A?displayProperty=nameWithType> attached property is `true` and the control has focus.|
|InvalidUnfocused|ValidationStates|The <xref:System.Windows.Controls.Validation.HasError%2A?displayProperty=nameWithType> attached property is `true` and the control does not have focus.|
