Maximize Client Area

Question

I have been wonderin if I could make my client form (a control) expand to a maximum view size when my main window is maximize and it should resize to a probable proportion when the main window is resized. Basically, what this means is, I mean thinkin if there's a way of settin my control's size dynamically with proportion to restore/resize and maximize button of the main window. note, my control is gonna be like the client area.
