Hi Michelle,
You're on the right track with the labelFunction. Give this a try:
private function getLabelUnit1(item:Object, column:DataGridColumn) :
Number
{
return item.CaServiceIds.getItemAt(0);
}
private function getLabelUnit2(item:Object, column:DataGridColumn) :
Number
{
return item.CaServiceIds.getItemAt(1);
}
<mx:columns>
<mx:DataGridColumn headerText="Content Name" dataField="ContentName"
width="64" wordWrap="true"/>
<mx:DataGridColumn headerText="Sellable Unit1"
labelFunction="getLabelUnit1" width="63" wordWrap="true"/>
<mx:DataGridColumn headerText="Sellable Unit2"
labelFunction="getLabelUnit2" width="63" wordWrap="true"/>
</mx:columns>
