How to deal with a multitude of controls on a form

Question

NewB to the forum, so if I posted this in the wrong place please let me know.

Does anyone know of a best method for dealing with large numbers of controls on a form?

I have a user interface form that will be driven by a TreeView control.  The various nodes need to call up one of about 9 different "pages" full of controls to display and allow manipulation of values.  Each of these "pages" holds enough controls to pretty much fill the remaining available form real estate.  I would love to throw a tab control on the form and each page of controls could reside on a tab so that I could layout and maintain each without have to move controls from another page out of the way.  However it is not desirable during runtime to have the tabs displaying. 

Suggestions?

Thanks,
B
