Dear Palli,

As for other panels, they should not have the same problem as this, because they don't have a header bar.

For winforms, honestly I have not any experience with that, but I have just tried a sample project, but did not find a HeaderedPanel control.

Hi River,

Your image was excellent and made it all clear.

I simplified your sample application downto what I think really matters in this case and opened an issue which you can track here.

Please check if you agree with this issue description and sample application show what you were reporting.
