ProgressBar Styles and Templates

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.

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.

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.

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"
NoteNote:

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.
