Remove/creat button programatically

Hi,

I'm having a simple ;-) problem:

In a Win Form I work on several tab pages, each one having its own controls in the container. As the Tab control is within a Win Form, I have some extra space that I want to use specifically when I pass from one Tab to another; in other words, in my Win Form there is a space I want to populate with controls (buttons) which are specific to the current/active tab but which are not part of that tab. However, I want to change the configuration of that "control population" - belonging to my Win Form - as per each active tab page. To simplify, that brings the basic question in the subject. Many thansk for hints!
