ProgressBar Styles and Templates
Microsoft Silverlight will reach end of support after October 2021. Learn more.
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 |
A FrameworkElement that displays a repeating pattern. |
|
ProgressBarIndicator |
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"
.gif "Note") 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.
