Need a panel or user control with a truely transparent background

[moondaddy]

I want to use a panel control which sits on top of another object which as a
gradient background. when I set the background color of the panel to
transparent, it just picks the darkest color from the background underneath
it. How can I make the panel (or a user control to behave like a panel) to
allow gradient color from behind it to show as if it truly was transparent?

Thanks

Thanks that looks like a great article. Is there a sample of the same
control in vb.net? I'm having trouble writing it from c# to vb.net.
