[flexcoders] ComboBoxes + Label in ItemRenderer

[quantum_ohm]

Hello,

How could I reference a label with a kind of 'selectedIndex' ?
It might sound dummy, but I'd like to follow the idea
(http://blog.dougco.com/category/coding/flex/) used with the
CBs to apply it to a label...
The problem is that the result in the label doesn't stay in its right
place when I scroll the DG.

Thx

Here is the code below :

<mx:HBox xmlns:mx="http://www.adobe.com/2006/mxml";
horizontalScrollPolicy="off"  dataChange="gridScrolled()">
