It does not update when scrolling the datagrid. Other times it does update, and other times it updates but on the wrong row. Here's the component: <?xml version="1.0" encoding="utf-8"?> <mx:HBox xmlns:mx="http://www.adobe.com/2006/mxml" horizontalScrollPolicy="off" verticalScrollPolicy="off" creationComplete="setItems();" > <mx:Script> <![CDATA[ [Bindable] private var pct:Number; [Bindable] private var pct_str:String; [Embed(source="assets/flag_red.png")] [Bindable] public var red:Class; [Embed(source="assets/flag_green.png")] [Bindable] public var green:Class; private function setItems():void{ // checking for data=null is neccessary since grid is created // before dataprovider is populated via webservice if(data != null){ trace('data.Pct:'+ data.Pct); pct = Number(data.Pct); if(pct <=85) img.source = green; if(pct > 85) img.source = red; pct_str = renderPercentText(String(data.Pct)); this.updateDisplayList(this.unscaledWidth, this.unscaledHeight); } } private function renderPercentText(t:String):String { return String(percentFormatShort.format(t))+"%"; } // :: for testing only :: // this click handler will render the cell correctly the image is clicked private function setImg(e:Event):void{ setItems(); } ]]> </mx:Script> <mx:NumberFormatter id="percentFormatShort" precision="0" /> <mx:Image id="img" width="16" height="16" right="0" click="setImg(event)" /> <mx:Text id="txt" text="{pct_str}" textAlign="right" width="44" /> </mx:HBox> Thanks for your help. -Jeff ------------------------------------ -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.comYahoo!
