Sorry... nevermind... issues with my dataProvider being set dynamically.On 6/12/06, Brendan Meutzner <[EMAIL PROTECTED]

            Hi,

I can't seem to get an itemRenderer to work properly with my DataGrid.
 I am trying to access the listData object to do some conditionals in
my renderer (eg. show a specific image based on row data).  However,
my listData property is not getting set properly.  Here's the renderer:

<?xml version="1.0" encoding="utf-8"?>
<mx:HBox xmlns:mx="http://www.adobe.com/2006/mxml" 
	 implements="mx.controls.listClasses.IDropInListItemRenderer"
	 width="100%"
	 horizontalAlign="center" verticalAlign="middle"
	 preinitialize="initComponent();">

	<mx:Image id="theImage" width="13" height="13"/>
	
	<mx:Script>
	<![CDATA[
	import mx.controls.dataGridClasses.DataGridListData;
	import mx.controls.listClasses.BaseListData;

								[Embed(source="/assets/images/arrow_down.png")]
	            [Bindable]
	            public var downArrow:Class;

				
				[Bindable]
				private var tmpSource:Class;

				private function initComponent():void
				{
					addEventListener("dataChange", handleDataChanged);
				}

				public function handleDataChanged(event:Event):void 
				{   
					trace("listData = " + DataGridListData(listData));
					theImage.source = downArrow;
				}   
				
				//Importing interface IDropInListItemRenderer requirements
				private var _listData:BaseListData;
			    public function get listData():BaseListData
			    {
			      return _listData;
			    }
			    public function set listData(value:BaseListData):void
				{
					_listData = value;
					dispatchEvent(new FlexEvent(FlexEvent.DATA_CHANGE));
				}
			]]>
		</mx:Script>
	
</mx:HBox>

I'm just calling this as itemRenderer="custom.display.MyItemRenderer"
from a datagrid column...

Any help is appreciated.

Thanks,

Brendan
