[flexcoders] Access inline itemrenderer from actionscript?

[candysmate]

I have an inline itemrenderer in a DataGridColumn thus:

<mx:DataGridColumn
 headerText="Column 2"
 dataField="col2">
  <mx:itemRenderer>
    <mx:Component>
      <mx:TextInput>
                                                
      </mx:TextInput>
    </mx:Component>
   </mx:itemRenderer>    
</mx:DataGridColumn>     

How can I access the properties of the TextInput from ActionScript
please?  I tried giving the TextInput an id but Flex scolded me.
