Let's assume that the panel contains the other three controls (the textbox, the label, and the button), and that it anchors them. When you anchor Control A to Control B, Control A will follow the movement of Control B and will keep its fixed distance from it. When you anchor a button to the left edge of its containing panel, for example, the button will follow the movement of the panel's left edge when you resize the panel. If you move the panel's left edge by 10 pixels to the left, for example, the button will also move 10 pixels to the left. The button will move to the right when you resize the panel inward (by moving its left edge to the right).
