Sets the windowed control's boundary properties all at once.
Use SetBounds to change all of the control's boundary properties at once. The same effect can be achieved by setting the Left, Top, Width, and Height properties separately. By setting all four properties at once, SetBounds ensures that the control will not repaint between changes
