string connstr = "Data Source=Akiii-PC;Initial Catalog=rgdb;User Id = sa;password = 12345";

            SqlConnection conn = new SqlConnection(connstr);
            SqlCommand cmd;
            SqlDataAdapter sda = new SqlDataAdapter();
            DataSet ds = new DataSet();
            DataView dv;

            try
            {
                conn.Open();
                cmd = new SqlCommand("select * from reg_table", conn);
                sda.SelectCommand = cmd;
                sda.Fill(ds, "reg_table");
                sda.Dispose();
                cmd.Dispose();
                conn.Close();

                dv = new DataView(ds.Tables[0]);
                dv.Sort = "name";
                int index = dv.Find("12333"); 

                if(index == -1)
                {
                    Response.Write("no result");
                }
                else
                {
                    GridView1.DataSource = dv;
                    GridView1.DataBind();
                    //Response.Write(dv[index]["Product_id"].ToString() + " " + dv[index]["Product_Name"].ToString());
                }               
            }
            catch (Exception ex)
            {
                Response.Write(ex.ToString());
            }
