This class represents a radio button control that allows a user to select one item from a selection of options. Each option in a group of radio buttons is a distinct RadioButton object, but each control shares the same GroupName. To determine whether a radio button has been selected, examine the Checked property. If you want to use a radio button with list data, the CheckBoxList control may be more convenient.

public class RadioButton : CheckBox {
// Public Constructors
   public RadioButton( );
// Public Instance Properties
   public virtual string GroupName{set; get; }
// Protected Instance Methods
   protected override void OnPreRender(EventArgs e);            // overrides CheckBox
}
