You probably want the valueCommit event.
Be aware that this event fires quite often, and you will need to check for null values and watch out for endless loops.

The Flex 3 reference says about the ComboBox change event: "Dispatched when the ComboBox contents changes as a result of user interaction, when the selectedIndex or selectedItem property changes, and, if the ComboBox control is editable, each time a keystroke is entered in the box." When I run this application and click on the MasterCard Button, the selectedItem property changes, but the change event is not dispatched - does somebody out there know why ?? Kilian here is the code (taken from adobe`s reference and made some changes): <?xml version="1.0"?> <!-- Simple example to demonstrate the ComboBox control. --> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml <http://www.adobe.com/2006/mxml> "> <mx:Script> <![CDATA[ import mx.collections.ArrayCollection; [Bindable] public var cards:ArrayCollection = new ArrayCollection( [ {label:"Visa", data:1}, {label:"MasterCard", data:2}, {label:"American Express", data:3} ]); private function changeHandler(event:Event):void { myLabel.text = "You selected: " + ComboBox(event.target).selectedItem.label; myData.text = "Data: " + ComboBox(event.target).selectedItem.data; } private function buttonHandler(event:Event):void { box.selectedItem = cards.getItemAt(1); } ]]> </mx:Script> <mx:Panel title="ComboBox Control Example" height="75%" width="75%" layout="horizontal" paddingTop="10" paddingBottom="10" paddingLeft="10" paddingRight="10"> <mx:ComboBox id="box" dataProvider="{cards}" width="150" change="changeHandler(event);"/> <mx:VBox width="250"> <mx:Text width="200" color="blue" text="Select a type of credit card."/> <mx:Label id="myLabel" text="You selected:"/> <mx:Label id="myData" text="Data:"/> </mx:VBox> <mx:Button label="MasterCard" click="buttonHandler(event);"> </mx:Button> </mx:Panel> </mx:Application>
