            This code should answer your question:


            <?xml version="1.0"?>
            <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
                  import mx.events.ValidationResultEvent;   
                  import mx.controls.Alert;
                  import mx.events.ItemClickEvent;
                  private function handleCard(event:ItemClickEvent):void {
                    if (event.currentTarget.selectedValue == "AmEx") {
                      Alert.show("You selected American Express."); 
                    } else if (event.currentTarget.selectedValue == "MC") {
                      Alert.show("You selected MasterCard.");
                    } else {
                      Alert.show("You selected Visa.");
                  private function handleValid(eventObj:ValidationResultEvent):void {
                      mx.controls.Alert.show("You must select a radio button.");
                      americanExpress.setStyle("color", "0xFF0000");
                      masterCard.setStyle("color", "0xFF0000");
                      visa.setStyle("color", "0xFF0000");          
                      americanExpress.setStyle("color", "0x000000");
                      masterCard.setStyle("color", "0x000000");
                      visa.setStyle("color", "0x000000");          
              <mx:Validator id="radioValidator" source="{cardtype}" 
                required="true" property="selectedValue" valid="handleValid(event)"
              <mx:RadioButtonGroup id="cardtype" itemClick="handleCard(event);"/>
              <mx:RadioButton groupName="cardtype" id="americanExpress"
