The following code example removes the first Control in the Control.ControlCollection of the derived class Panel if the count of the collection is greater than zero. The example requires that you have created a Panel, a Button, and at least one other control on a Form. The other controls are added to the Panel control, and the Panel control added to the Form. When the button is clicked, the first control contained in the panel is removed from the Control.ControlCollection.
