Set DataGrid headerRenderer dynamically

Hi Flex newbie so be gentle. I've got a function to create a new colummn in a grid ...              private function addBlankDataGridColumn(dataField:String):void             {                 var dgc:DataGridColumn = new DataGridColumn(dataField);                 dgc.headerText="hi2";                 dgc.headerRenderer="VDGHeader";                 var cols:Array = musicDatagrid.columns;                 cols.push(dgc);                 musicDatagrid.columns = cols;             } This works fine apart from the line dgc.headerRenderer="VDGHeader"; I can set the headerRenderer="VDGHeader" as a parameter in predefined columns and it works fine, but in the function above it causes the following error 1067: Implicit coercion of a value of type String to an unrelated type mx.core:IFactory. I've tried dgc.setHeaderRenderer("VDGHeader"); but no luck. Can you set the headerRenderer dynamically? Thanks Brian
