get all data used in gridview.databind()

[Sergio E.]

Hello, I follow tried to extend the control gridview and not yet it is
possible to me to have access to the data with which this one is filled. I
already tried to override the DataSource property but I only obtain results
when datasource is a datatable, nevertheless what I need now is to collect
these data when datasourceid corresponds to sqldatasource. Thousand thanks
for the aid.
