[flexcoders] Re: Datagrid - Using and Editing Data From XMLListCollection

You would need to add an event listener for the itemeditend event. Then grab 
the data that was edited and modify the dataprovider.

 Thanks.

Thanks for the help. I did try using an itemEditEnd eventlistener. The issue I 
was having was that the data value wasn't being changed it was still the 
original value.

Thanks. I will try your updateData function. I was trying to grab the data in a 
different manner. I believe I was using the following:

private function endEdit(event:DataGridEvent):void {

trace('event.itemRenderer.data - ' + 
event.itemRenderer.data)

}
I will try your method and am guessing that it will work. 

Thanks for the assistance.
