[flexcoders] Setting style for inline itemrenderer?

[candysmate]

My datagrids have a style set for them. My inline itemrenderer for one
of the columns requires a different style. I have tried:

<mx:DataGridColumn
 width="30"
 editable="false"
 headerText=""
 dataField="problem"
 textAlign="center"                                                             
 >                                                                          
<mx:itemRenderer>                                                    
<mx:Component>
    <mx:Text  styleName="myStyle">
    </mx:Text>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>    

without success. Any pointers most welcomed.
