DockPanel Docked Opacity


Can you help me to make a transparent docked panel ?

My code looks like this

        <StackPanel>            <Image Url=""/&gt; 
            <Panel Background="#eeeeee" Height="40"/>            <Text Margin="20" TextWrapping="Wrap" Value="Lorem ipsum dolor sit amet, consectetur adipiscing elit." />

    <BottomBarBackground Dock="Bottom"/>

    <Panel Dock="Bottom" Height="50" Opacity="0.8">

        <Rectangle Fill="#89eff2" Layer="Background" Opacity="0.8"/>



But it doesn’t do the trick (my text is way longer, and I’like the user to still see it under the panel )

By setting

<ScrollView Layer="Background">

it works
