Try using Session variables (Session["QueryList"])

for (int rowCount = 0; rowCount < dataTable.Rows.Count;rowCount++ )
        {
            query.Add(dataTable.Rows[rowCount]);

ViewState["QueryList"] = query;

list = (ArrayList)ViewState["QueryList"];

for (int rowCount = 0; rowCount < list.Count; rowCount++)

    DataRow dataRW = (DataRow)list[rowCount]; //add it to desired data table... :)
