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 }
