Show/hide controls as needed...

I'm trying to implement a lot of controls on a limited space without using tabs, so what's the best way to do that at design time? The panel control seems transparent straight through to the form, so I tried overlaying two panels together and I was going to hide one and show the other but that's not going to work.

Is that gonna tax a user's system anyway? Should I create the controls at run time when I need them? And if I wanted to do that, what's the best way to do it, have methods within my main form's class that create the controls and call the methods when I need to show them?

I really could use a quick reply on this, don't need a whole lot of info just some quick explanation.

Try Groupbox control instead of panel.
