[flexcoders] Re: How to populate an attribute value in DataGrid control?

Tracy,

Thanks for the feedback.

Unfortunately I cannot change the XML, the data is from third party
provider. I tried it with labelFunction and @@, it does not work :-(

var sFirstName:String = xmlRecord.data[0].(@@name ==
"lastname").@@value;
