How to get the index for itemrenders

Question

I have an itemrender with a button. I'd like to disable the button for the first and last object in my itemrenderer (list). Can any provide a simple example how to accomplish this task?
Thanks for your assistance.

Hi madhooper,
You can try this way..make use of Boolean variable..
<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" >
    <mx:Script>
        <![CDATA[
          import mx.collections.ArrayCollection;
          [Bindable]
          private var initDG:ArrayCollection = new ArrayCollection([
            {Artist:'Pavement1', Album:'Slanted and Enchanted', Price:11.99, IsEnabled:false},
            {Artist:'Pavement2', Album:'Brighten the Corners', Price:178.99, IsEnabled:true},
            {Artist:'Pavement3', Album:'Enlighten the Corners', Price:174.99, IsEnabled:true},
            {Artist:'Pavement4', Album:'Borade the Corners', Price:431.99, IsEnabled:true},
            {Artist:'Pavement5', Album:'Corners of Edges', Price:221.99, IsEnabled:true},
            {Artist:'Pavement6', Album:'Maniacal Palace', Price:32.99, IsEnabled:false}
        ]]>
    </mx:Script>
    <mx:Panel paddingTop="10" paddingBottom="10"
        paddingLeft="10" paddingRight="10">
        <mx:DataGrid id="myGrid" dataProvider="{initDG}"
            width="100%" editable="true">
            <mx:columns>
                <mx:DataGridColumn dataField="Artist" resizable="true"/>
                <mx:DataGridColumn dataField="Album" resizable="true"/>
                <mx:DataGridColumn dataField="Price" resizable="true"/>
                <mx:DataGridColumn editable="false">
                 <mx:itemRenderer>
                  <mx:Component>
                   <mx:Button enabled="{data.IsEnabled}" label="Edit" />
                  </mx:Component>
                 </mx:itemRenderer>
