Hi again, When using query as return type you don't need to set columnName in your datagridColumn in uppercase. Uppercase is just when referencing to structures returned from coldfusion.

I think I am almost there. I have my CFC now returning a query and have eliminated all errors. But, when I trigger my click event it seems to return the query in my DG however no text is visible (when you scroll over the DG it highlights each item, but not text is visible). Also, since I am now returning a wuery I no longer need to loop over query result and insert each record into an individual structure and append that to an array...correct? (or is that still necessary?) I did configure my CFC both ways though and got the same result...a DG with no text, but obvisouly filled with somthing do to highlighting. I have posted what I have so far.
