[flexcoders] Selecting an Editor for a DataGridColumn at runtime - how?

[garyq22]

Hello Group

I would like to select an Editor for each cell in my DataGrid
depending on other data values that might be in the same row.

I believe I can use the itemEditBegin event to assign and create my
chosen editor. I've got this far and I'm well stuck.

I know the following doesn't work - I just posted it to show that I am
trying :-)

Any assistance greatly appreciated!

private function onItemEditBegin(event:DataGridEvent):void
{
 var dgc:DataGridColumn;
 dgc = 
event.currentTarget.columns[event.currentTarget.editedItemPosition.columnIndex];
 if (dgc != null)
 {
  dgc.itemEditor = IFactory(mx.controls.NumericStepper);
  event.currentTarget.createItemEditor();
 }
}
