hi please make sure ur renderer implements the following interfaces: mx.controls.listClasses.IDropInListItemRenderer mx.managers.IFocusManagerComponent
Then your component should look like this: <mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml"; width="150" height="20" horizontalScrollPolicy="off" verticalScrollPolicy="off" implements="mx.controls.listClasses.IDropInListItemRenderer,mx.managers.IFocusManagerComponent" > <mx:Script> <![CDATA[ import mx.controls.dataGridClasses.DataGridColumn; import mx.controls.listClasses.ListData; import mx.controls.dataGridClasses.DataGridListData; import mx.controls.listClasses.BaseListData; import mx.controls.dataGridClasses.DataGridItemRenderer import mx.events.FlexEvent; [Bindable] private var _data:Object; private var _dataChanged:Boolean; private var _listData:DataGridListData; override public function drawFocus(draw:Boolean):void { rie.setFocus(); } override public function set data(value:Object):void{ super.data = value; _data = value; //make sure commitProperties runs and sets the properties //on the child components _dataChanged = true; invalidateProperties(); } override protected function commitProperties():void{ super.commitProperties(); if (_dataChanged){ rie.htmlText = ""; rie.htmlText = _data.attribute('comments'); //rie.invalidateProperties() //theImage.source=_data.attribute('data'); //theLabel.text=_data.attribute('label'); } } public function get text():String { return rie.htmlText; } public function get listData():BaseListData { return _listData; } public function set listData(value:BaseListData):void { _listData = DataGridListData(value); if(value.owner is DataGridColumn){ this.invalidateDisplayList() } } override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void{ super.updateDisplayList(unscaledWidth,unscaledHeight); } ]]> </mx:Script> <mx:Text id="rie" width="100%" height="100%"/> </mx:VBox> On Thu, Oct 8, 2009 at 11:09 AM, Ajay Kostha <[email protected]> wrote: > > Hi All > > I have a DataGrid in which I am using a custom image renderer.
