WPF: How to autosize Path to its container?

Question

I have a Path that must resize to its StackPanel container.

<StackPanel x:Name="TrackSurface">
    <Path Fill="AliceBlue"
          Stroke="Black" StrokeThickness="1"
          Data="{StaticResource TranslateZ}">
    </Path>
</StackPanel>

I think about using a transformation bound to the container but don't know how to it actually. Can someone give me hint?

Answer 1

I changed the Stackpanel to Grid and Stretch property of the Path to Fill.

<Grid x:Name="TrackSurface"> 
<Path Fill="AliceBlue" 
Stretch="Fill"
      Stroke="Black" StrokeThickness="1" 
      Data="M148,28 C221,133 110.50025,119.5 110.50025,119.5 L124.50016,68.5 z"> 
</Path>
