[ This article is for Windows 8.x and Windows Phone 8.x developers writing Windows Runtime apps. If you’re developing for Windows 10, see the latest documentation ]

This topic describes the styles and templates for the ProgressBar control. You can modify these resources and the default ControlTemplate to give the control a unique appearance.

Visual states

These are the VisualStates defined in the control's default style.

VisualState name	VisualStateGroup name	Description
`Determinate`	`CommonStates`	The ProgressBar reports progress based on its Value property. IsIndeterminate is false.
`Indeterminate`	`CommonStates`	The ProgressBar reports generic progress with a repeating pattern. IsIndeterminate is true.
`Updating`	`CommonStates`	The ProgressBar is updating.
`Error`	`CommonStates`	The process showing progress has an error. ShowError is true.
`Paused`	`CommonStates`	Progress is paused. ShowPaused is true.

Theme resources

These resources are used in the control's default style.

Dark theme brushes

To change the colors of the control in the dark theme, override these brushes in App.xaml.

<SolidColorBrush x:Key="ProgressBarBackgroundThemeBrush" Color="#59FFFFFF" />
<SolidColorBrush x:Key="ProgressBarBorderThemeBrush" Color="Transparent" />
<SolidColorBrush x:Key="ProgressBarForegroundThemeBrush" Color="#FF5B2EC5" />
<SolidColorBrush x:Key="ProgressBarIndeterminateForegroundThemeBrush" Color="#FF8A57FF" />

Light theme brushes

To change the colors of the control in the light theme, override these brushes in App.xaml.

<SolidColorBrush x:Key="ProgressBarBackgroundThemeBrush" Color="#30000000" />
<SolidColorBrush x:Key="ProgressBarBorderThemeBrush" Color="Transparent" />
<SolidColorBrush x:Key="ProgressBarForegroundThemeBrush" Color="#FF4617B4" />
<SolidColorBrush x:Key="ProgressBarIndeterminateForegroundThemeBrush" Color="#FF4617B4" />

Other resources

<x:Double x:Key="ProgressBarThemeMinHeight">6</x:Double>
<Thickness x:Key="ProgressBarBorderThemeThickness">0</Thickness>

For more info on theme resources, including the values that are used for the HighContrast theme, see XAML theme resources reference.

                                         here.  The FadeOutThemeAnimation is necessary in the Indeterminate state so
                                         that we can do a FadeInThemeAnimation when transitioning back to the
                                         Determinate state.  The DoubleAnimation on Opacity is necessary to hide the
                                         DeterminateRoot immediately so that it does not slowly fade out during each
                                         iteration of the Indeterminate state animation. -->
