If you are a Asp.Net developer you are more interested in writing code behind file to separate logic from interface.

This is a simple example to show code behind in flex
CodeBehindTest.mxml

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" 
 layout="absolute" creationComplete="initApp();">
 <mx:Script>
  <![CDATA[
   include "CodeBehindTest.as";
  ]]>
 </mx:Script>
 <mx:Button id="btnMessage" label="Show Message"/>
</mx:Application>

In the above code we included the code behind file in main mxml


This is actual code behind action script file
CodeBehindTest.as

// ActionScript file
import flash.events.MouseEvent;
import mx.controls.Alert;
private function initApp():void
{
 btnMessage.addEventListener(MouseEvent.CLICK,ShowMessage);
}
private function ShowMessage(e:MouseEvent):void
{
 Alert.show("Message from codebehind");
}

Madhu :-)
