Making individual row or cell editable or readonly depend on cell data

Question

Dear expert
I'm working with dataGrid and itemEditor. I can make some
column editable. But I would like to know how to set some specific
row or cell editable or readonly depend on cell data. Could anybody
guide me which method should I override or any idea?
Thanks

Well a simply way would be if the row contained some kind of
data that had the info to determine if it was editable or not...
e.g. say the data in the dataProvider of the dataGrid has a field
called jobTitle and you didn't want cells in that row editable when
the jobTitle is "Executive".
<mx:DataGrid dataProvider="{jobData}" editable="true">
<mx:columns>
<mx:Array>
<mx:DataGridColumn headerText="Title" dataField="Title"
itemEditor="titleEditor"/>
<mx:DataGridColumn headerText="Phone" dataField="Phone"
itemEditor="phoneEditor"/>
</mx:columns>
</mx:DataGrid>
Your itemEditor's could check to see if thats the case.
phoneEditor.mxml
<?xml version="1.0"?>
<mx:TextInput xmlns:mx="
http://www.adobe.com/2006/mxml"
text="{data.Phone}" creationComplete="checkIfEditable()" >
<mx:Script>
public function checkIfEditable():void
if(data.Title == 'Executive') this.editable=false;
</mx:TextInput>
