Set DataGridColumn editable based on row data

Question

I searched for this but did not find a direct answer. People wanted something similar but not exactly the same.
I have several columns in a standard datagrid that I would like to set editable if the data.company_id > 0. Is this possible? Here's my MXML code:
<mx:DataGridColumn headerText="Part Number"
                   dataField="part_number"
                   editable="false"
                   itemRenderer="controls.setTextColor"/>
I tried:
<mx:DataGridColumn headerText="Part Number"
                    dataField="part_number"
                    editable="{data.company_id > 0 ? true : false;}"
                    itemRenderer="controls.setTextColor"/>
But of course that would be too easy, right?
Help greatly appreciated...

aha, you're in luck
Very quick and rough, but it works like a charm
XML (written from php)
<?php
     echo
     <thing>
          <edit>true</edit>
          <value>10</value>
     </thing>
     <thing>
          <edit>false</edit>
          <value>1000</value>
     </thing>
     <thing>
          <edit>false</edit>
          <value>550</value>
     </thing>
     <thing>
          <edit>true</edit>
          <value>20</value>
     </thing>
?>
Flex
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="stuff.send()">
    <mx:HTTPService id="stuff" showBusyCursor="true" method="POST" url="http://localhost/stuff.php"/>
    <mx:DataGrid id="blah" x="240" y="93" dataProvider="{stuff.lastResult.thing}" editable="{blah.selectedItem.edit}">
        <mx:columns>
            <mx:DataGridColumn dataField="value" editable="{data.edit}"/>
        </mx:columns>
    </mx:DataGrid>
</mx:Application>
so yeah, i'd assume you'd have to edit the actually datagrid editable properties, rather than just the datagrid column. If your function doesn't work in there then just feed it a direct boolean value like i did.
