[.NET] - Using Anchoring and Docking

Although both anchoring and docking are useful while resizing windows application, the anchor can keep control of its size and its location in relation to control container when the container is not attached to particulae edge of the container, but somewhere in the middle. 

The Docking feature attaches a control to the edge of its container. When a control is docked to an edge of it's container, it will always stick to that edge. The control will also resize itself to fully fit the edge of the container and also resizes as the container is resized. The Dock property of the Form control can be set to any one of the six values, Top, Bottom, Left, Right, Fill, and None.

Anchoring specifies how a control anchors to the edges of its container. When a control is anchored to an edge of its container, the distance between the control and the specified edge remains constant when the container resizes. For example, if a control is anchored to the right edge of its container, the distance between the right edge of the control and the right edge of the container remains constant when the container resizes. A control can be anchored to any combination control edges. If the control is anchored to opposite edges of its container (for example, to the top and bottom), it resizes when the container resizes.
