Ok... In the parent component to the datagrid I used an initialize event:
public function initDg():void {
if(dgOrdExt.selectedItem["Kind"]=="LONG")dgOrdExt.Profit.dataField="Profit";
if(dgOrdExt.selectedItem["Kind"]=="SHORT")dgOrdExt.Profit.dataField="ShProfit";
}
it does not work. but if I replace the code with dgOrdExt.dataField="Profit";
which just sets the dataField without referencing the other column the code is
all working...
I also tried creationcomplete event and that did not work either.
