            Database _db = DatabaseFactory.CreateDatabase();

            DataSet ds = new DataSet();
            SqlConnection Conn = new SqlConnection(ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString);

                {
                    List<string> ajaxDataCollection = new List<string>();
                    DataTable dt = new DataTable();
                    dt = getdata(prefixText);
                    if (dt.Rows.Count > 0)
                    {
                        for (int i = 0; i < dt.Rows.Count; i++)
                        {
                            ajaxDataCollection.Add(dt.Rows[i]["Name"].ToString());
                        }
                    }
                    return ajaxDataCollection.ToArray();
                }
            public DataTable getdata(string prefixText)
            {
                SqlConnection Conn = new SqlConnection(ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString);
                string query = "select * from SHOPHIVECAT";

                SqlDataAdapter sda = new SqlDataAdapter(query, Conn);
                DataTable dt = new DataTable();

                sda.Fill(dt);
                return dt;
            }
        }}}
