อยากถามเรื่องการแสดงข้อมูลใน gridview ข้อมูลมันไม่แสดงทุก field ค่ะ

private void cmdSearch_Click(object sender, EventArgs e)
        {
            string sqlSearch = "";
            string d1 = startDate.Value.Day + "/" + startDate.Value.Month + "/" + startDate.Value.Year;
            string d2 = EndDate.Value.Day + "/" + EndDate.Value.Month + "/" + EndDate.Value.Year;

            sqlSearch = "SELECT OrderCustomer.OrderCustomerID, OrderCustomer.CustomerID,Product.ProductName,";
            sqlSearch += " OrderCustomer.OrderCustomerDate, OrderCustomer.OrderCustomerStatus, OrderCustomerDetail.*,Product.ProductID";
            sqlSearch += " FROM Customer, Product, OrderCustomerDetail INNER JOIN OrderCustomer ON OrderCustomerDetail.OrderCustomerID = OrderCustomer.OrderCustomerID";
            sqlSearch += " WHERE (OrderCustomer.OrderCustomerDate BETWEEN #" + d1;
            sqlSearch += " # AND #" + d2 + "#)";
            sqlSearch += " AND (OrderCustomer.OrderCustomerStatus='1')";
            sqlSearch += " AND (OrderCustomerDetail.OrderCustomerID=OrderCustomer.OrderCustomerID)";
            sqlSearch += " AND (Product.ProductID=OrderCustomerDetail.ProductID)";
            sqlSearch += " ORDER BY OrderCustomer.OrderCustomerDate DESC";

            com = new OleDbCommand();

            da = new OleDbDataAdapter(sqlSearch, Con);
            da.Fill(ds, "OrderCustomer");

            if (ds.Tables["OrderCustomer"].Rows.Count != 0) {
                cmdPrint.Enabled = true;

                dgvOrderCustomer.DataSource = ds.Tables["OrderCustomer"];
                CalculateNetPrice();

            } else {
                dgvOrderCustomer.DataSource = null;
                MessageBox.Show("ไม่่มีรายการสั่งซื้อในวันที่" + " " + startDate.Value.ToShortDateString() + " " + "ถึง" + " " + EndDate.Value.ToShortDateString(), "ผลการตรวสอบ", MessageBoxButtons.OK, MessageBoxIcon.Information);
            }
            FormatDgvData();
