Why isn't this displaying anything?

Code:
			sSQL.Append("Select * from _tech_review");

			CRAB.COMPSERV.SQLConn conn = new CRAB.COMPSERV.SQLConn(db,server);
			ds = conn.SelectSqlData(sSQL.ToString(), "_tech_review", true);
			dlPrintable.DataSource = ds.Tables[0].DefaultView;
			dlPrintable.DataBind();
I debugged it and the DataSet is returning something, but when I run the page it display nothing, no error.
