Kevin, As long as the function reference is passed in through your column object, you should be able to set it like you have already.
Here's an example using your creation method for the datagrid column: <mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"; initialize="initPage()"> <mx:DataGrid id="myDG" width="100%" height="200" /> <mx:Array id="dgArray"> <mx:Object firstname="Brendan" lastname="Meutzner" age="25" occupation="Flex/Flash Developer" /> <mx:Object firstname="Clint" lastname="Modien" age="27" occupation="Flex Developer/Architect" /> <mx:Object firstname="Ben" lastname="Luckyk" age="28" occupation="Flex/Java Developer" /> </mx:Array> <mx:Script> <![CDATA[ import mx.controls.gridclasses.DataGridColumn; private function initPage():Void { myDG.addColumn(createDataGridColumn({columnName:"name", headerText:"Name", labelFunction:this["setName"], width:150})); myDG.addColumn(createDataGridColumn({columnName:"age", headerText:"Age", width:50})); myDG.addColumn(createDataGridColumn({columnName:"occupation", headerText:"Occupation"})); myDG.dataProvider = dgArray; } function createDataGridColumn(columnProps:Object):DataGridColumn { var _dgc:DataGridColumn = new DataGridColumn(columnProps.columnName); _dgc.headerText = columnProps.headerText; if(columnProps.width) { _dgc.width = columnProps.width; } if(columnProps.labelFunction) { _dgc.labelFunction = columnProps.labelFunction; } return _dgc; } function setName(row:Object):String { return row.lastname + ", " + row.firstname; } ]]> </mx:Script> </mx:Application> Brendan --- In flexcoders@yahoogroups.com, "Kevin Ewok" <[EMAIL PROTECTED]> wrote: > > Brendan- > Thanks for your response.
