ProgressBar Styles and Templates

ProgressBar Styles and Templates

Collapse All

Silverlight

This topic describes the styles and templates for the ProgressBar control. You can modify the default ControlTemplate to give the control a unique appearance. For more information, see Customizing the Appearance of an Existing Control by Using a ControlTemplate.

ProgressBar Parts

The following table lists the named parts for the ProgressBar control.

Part	Type	Description
ProgressBarTrack	FrameworkElement	A FrameworkElement that displays a repeating pattern.
ProgressBarIndicator	FrameworkElement	A FrameworkElement that fills based on a value.

ProgressBar States

The following table lists the visual states for the ProgressBar control.

VisualState Name	VisualStateGroup Name	Description
Determinate	CommonStates	ProgressBar reports progress based on the Value property.
Indeterminate	CommonStates	ProgressBar reports generic progress with a repeating pattern.

Default Style and Template

The following shows the XML namespace mapping that you have to specify when you work with styles and templates.

<!-- XML Namespace mapping. -->
xmlns:vsm="clr-namespace:System.Windows;assembly=System.Windows"

Note:
The default templates still specify the vsm: XML namespace mapping for the VisualStateManager element for legacy reasons. You can however, use the VisualStateManager element without specifying the vsm: mapping.

The following XAML shows the default style and template for the ProgressBar control.
