hi fried,
use dock property.
design time:
right click on the Control->properties->Dock->yourOption(right,fill,left,bottom).
code window: for example button control
button1.Dock = DockStyle.Fill;
button1.Dock = DockStyle.Bottom;
button1.Dock = DockStyle.Left;
button1.Dock = DockStyle.None;
button1.Dock = DockStyle.Right;
button1.Dock = DockStyle.Top;
