I am trying to maximize a web part. When the maximize event is fired
(by overwriting CreateWebPartMenu() method), I am able to expand the
display area of the Web Part; however, I am not able to make the
other Web Parts in the same web zone invisible. Consequently, I can
only enlarge the Web Part, not maximize. Any suggestions?

I tried to set the [b]IsVisible[/b] property of the web part to false
to make the other web parts in the web zone to be invisible. It seems
it does not work.
