Examples

<-- Below is an example definition of the PART_Indicator for the AnimatedProgressBar. A similar definition could be
used for the ProgressBar control. -->
<Rectangle x:Name="PART_Indicator">
   <Rectangle.Fill>
       <MultiBinding>
           <MultiBinding.Converter>
               <themes:ProgressBarSegmentedBrushConverter />
           </MultiBinding.Converter>
           <Binding Path="IsContinuous" RelativeSource="{RelativeSource TemplatedParent}" />
           <Binding Path="Orientation" RelativeSource="{RelativeSource TemplatedParent}" />
           <Binding Path="ActualWidth" ElementName="PART_Indicator" />
           <Binding Path="ActualHeight" ElementName="PART_Indicator" />
           <Binding Path="ActualWidth" ElementName="PART_Track" />
           <Binding Path="ActualHeight" ElementName="PART_Track" />
           <Binding Path="IsIndeterminate" RelativeSource="{RelativeSource TemplatedParent}" />
