How to set the flyout background transparent

[jeff9571]

I follow the documentation to style the flyout, the background can be set to other colors, but not transparent.
Here is the style:
<Style Selector="FlyoutPresenter.DefaultFlyout"> <Setter Property="Background" Value="Transparent" /> <Setter Property="Padding" Value="0" /> </Style>
Here is the button's flyout
<Button.Flyout> <Flyout FlyoutPresenterClasses="DefaultFlyout" Placement="Bottom" ShowMode="Standard"> <StackPanel> <Button Content="Test" HorizontalAlignment="Stretch"></Button> </StackPanel> </Flyout> </Button.Flyout>
