The source of the data is irrelevant. setItemAt() is a method of the *collection*, and can be used with any collection.
What is the data type of the DG dataProvider? What error are you getting? "...im only changing the data in the grid..." No, you are not. You are changing the data in the dataProvider. When you loop to build your server update data, you will be working with the dataProvider.

So would setItemAt() still work your code works perfect for Array example but i get an error on setting the httpservice dataprovider search_cert_refund_dataprovider.setItemAt(oSelectedItem,iIndex); remember im only changing the data in the grid so i can later loop it to post back to my code. --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Tracy Spratt" <tspr...@...> wrote: > > It is not taking a long time to display, it will never display. > > > > The problem is with the way you are updating the dataProvider.
