Question

how to generate serial number using labelFunction in datagrid?

Answer 1

What do mean by generating serial number? Based on what?

Edit:

<fx:Script>

private function myLabelFunc(item:Object, col:AdvancedDataGridColumn):String
{
var itemIndex:int = dataprovider.getItemIndex(item);
return itemIndex.toString();
}

<mxml>
<mx:AdvancedDataGridColumn headerText="Serial No." labelFunction="myLabelFunc"/>
