Hi Mohanraj, It's very much possible, I have modified the previous example to dispatch events....It would give you some idea, how you can achieve the same.
I am using Metadata tag for mxml components, you can find more about in docs. ##main.mxml### <mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"; xmlns="*"> <mx:Script> <![CDATA[ var dp:Array = [ {label:"Abdul",data:1}, {label:"Manish",data:2}, {label:"Sam", data:3} ]; function startListening() { //you can also subscribe to change event of comp1 on this way... cmp1.addEventListener("change", mx.utils.Delegate.create(this, onCMP1Change)); } function onCMP1Change(event) { cmp2.textValue = event.target.selectedItem.label; } ]]> </mx:Script> <!-- you can assign event handlers to change attribute also. Following lin is commented now../--> <!-- <comp id="cmp1" dataProvider="{dp}" chnage="onCMP1Change(event);"/> /--> <comp1 id="cmp1" dataProvider="{dp}"/> <comp2 id="cmp2" creationComplete="startListening();" /> </mx:Application> ##comp1.mxml### <mx:VBox xmlns:mx="http://www.macromedia.com/2003/mxml";> <mx:Metadata> <!-- this tells the compiler to embed relevant code, so that you can broadcast 'change' event /--> [Event("change")] </mx:Metadata> <mx:Script> <![CDATA[ public var dataProvider:Array; public var selectedItem:Object; //call this function from change handler of combobox and this function dispatches the change event.. function onSelectionChange(event) { selectedItem = event.target.selectedItem; dispatchEvent({type:'change'}); } ]]> </mx:Script> <mx:ComboBox id="_cb" dataProvider="{dataProvider}" change="onSelectionChange(event);"/> </mx:VBox> ##comp2.mxml### <mx:VBox xmlns:mx="http://www.macromedia.com/2003/mxml";> <mx:Script> <![CDATA[ var textValue:String; ]]> </mx:Script> <mx:TextInput id="_ti" text="{textValue}"/> </mx:VBox> About Metadata tag: http://livedocs.macromedia.com/flex/15/flex_docs_en/00000459.htm Hope that helps... -abdul -----Original Message----- From: Mohanraj Jayaraman [mailto:[EMAIL PROTECTED] Sent: Saturday, April 09, 2005 4:13 AM To: [email protected] Subject: RE: [flexcoders] Exchanging data between MXML Components Hi Abdul and Tracy, Thanks for the example.It works, but I was expecting an event driven model instead of binding to exchange data between components. Can the same be explained with broadcast/listener model?
