Can someone post an example of embedding a conditional statement in a repeater? For example in the sample below if the currentItem is 3 change the button color to blue.



<?xml version="1.0"?>
<!-- Simple example to demonstrate the Repeater class. -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
 
<mx:Script>
<![CDATA[
 
import mx.controls.Alert;
 
[Bindable]
private var dp:Array = [1, 2, 3, 4, 5, 6, 7, 8, 9]; 
 
]]>
</mx:Script>
 
<mx:Panel title="Repeater Example" width="75%" height="75%" 
paddingTop="10" paddingLeft="10" paddingRight="10" paddingBottom="10">
 
<mx:Text width="100%" color="blue" 
text="Use the Repeater class to create 9 Button controls in a 3 by 3 Tile container."/>
 
<mx:Tile direction="horizontal" borderStyle="inset" 
horizontalGap="10" verticalGap="15"
paddingLeft="10" paddingTop="10" paddingBottom="10" paddingRight="10">
 
<mx:Repeater id="rp" dataProvider="{dp}">
<mx:Button height="49" width="50" id="Button1"
label="{String(rp.currentItem)}"
click="Alert.show(String(event.currentTarget.getRepeaterItem()) + ' pressed')"/>
</mx:Repeater> 
</mx:Tile>
 
</mx:Panel> 
</mx:Application>
