How to change the size of Rich Text Box when I maximize the window?

Question

How can I change the size of Rich Text Box or Web Browser automatically when I change the size of the window? The problem is when I maximize the window, Rich Text Box (or Web Browser) keeps the same size and only the window gets bigger...
