updateDisplayList is for updating all visuals including the text in labels. I think I would call itemRendererToIndex in updateDisplayList and modify the text at that time. Actually, I'd probably have a separate label just for the number and modify that. ------------------------------ *From:* [email protected] [mailto:[EMAIL PROTECTED] *On Behalf Of *williamkusumo *Sent:* Thursday, June 14, 2007 12:44 PM *To:* [email protected] *Subject:* [flexcoders] Re: Show incremental numeric index in a List Thanks for the feedback, guys! I implemented IDropInListItemRenderer and got ahold of listData.owner. You are right, itemRendererToIndex(...) will get you the correct index. The trouble now is how do I bind the result of itemRendererToIndex to a label inside the itemRenderer so that it automatically updates when the dataProvider is changed? You mentioned overriding updateDisplayList(), isn't that function related more to updating the styles?
