I have two TabControls on a single C# Form. One TabControl on above the other one like so...

TabControl1
Resizer
TabControl2

Between both TabControls, I want to give the user the ability to resize both controls by moving a single bar. The window should stay the same size.

Do I use a resize window? Or a Splitter? Or something else? Any code examples would also be appreciated.

Thanks!
