これはあなたを助けるかもしれません..!! これは私のコードです..!!テンプレートフィールドのtexbox IDを置き換えることができます..!! 文字列値をデータベースのテーブルに保存する方法を知っていると思います..!! このコードで十分だと思います.!! 私はあなたから知りたい.. !!

 try
    {
        for (int i = 0; i < gvInvTransaction.Rows.Count - 1; i++)
        {
            TextBox txtproduct = (TextBox)gvInvTransaction.Rows[i].FindControl("txtProduct");
            TextBox txtBarcode = (TextBox)gvInvTransaction.Rows[i].FindControl("txtBarCode");
            TextBox txtPrdctBatchID = (TextBox)gvInvTransaction.Rows[i].FindControl("txtPrdctBatchID");
            TextBox txtPrdctID = (TextBox)gvInvTransaction.Rows[i].FindControl("txtPrdctID");
            TextBox txtStdPurchasePrice = (TextBox)gvInvTransaction.Rows[i].FindControl("txtUnitPrice");
            TextBox txtStdSalesPrice = (TextBox)gvInvTransaction.Rows[i].FindControl("txtUnitPrice");





            string  ProductID = Convert.ToInt64(txtPrdctID.Text);
            string  StdPurchasePrice = Convert.ToDouble(txtStdPurchasePrice.Text);
            string  StdSalesPrice = Convert.ToDouble(txtStdPurchasePrice.Text);







        }
    }
    catch (Exception ex) { }
}

他の 2 つのデータベース挿入用に別の文字列と Sql コマンドオブジェクトを作成し、パラメーターを追加します。パラメーターには、gridview から取得した文字列値を渡し、cmd2.ExecuteNonQuery(); を呼び出します。そしてcmd2.execute..!! 以下は単なるサンプルです。各ビューの値に置き換えてください..!! それが役に立てば幸い..！！:)

 protected void Button1_Click(object sender, EventArgs e)
{
    string insrt = "insert into book_mas_det(book_date,book_from,book_to,travel_date,return_date,adult_pax,child_pax,travel_class,contact_name,pnr_no,tot_amt,adv_amount,travler_rmks,agent_rmks) values (@a,@b,@c,@d,@e,@f,@g,@h,@i,@j,@k,@l,@m,@n)";
    string insrt2 = "insert into book_mas_det(book_date,book_from,book_to,travel_date,return_date,adult_pax,child_pax,travel_class,contact_name,pnr_no,tot_amt,adv_amount,travler_rmks,agent_rmks) values (@a,@b,@c,@d,@e,@f,@g,@h,@i,@j,@k,@l,@m,@n)";
    string insrt3 = "insert into book_mas_det(book_date,book_from,book_to,travel_date,return_date,adult_pax,child_pax,travel_class,contact_name,pnr_no,tot_amt,adv_amount,travler_rmks,agent_rmks) values (@a,@b,@c,@d,@e,@f,@g,@h,@i,@j,@k,@l,@m,@n)";

    MySqlCommand cmd = new MySqlCommand(insrt, conn);
    MySqlCommand cmd2 = new MySqlCommand(insrt2, conn);
    MySqlCommand cmd3 = new MySqlCommand(insrt3, conn);

    //cmd parameters
    cmd.Parameters.AddWithValue("@a", txtbookingdate.Text);

    cmd3.ExecuteNonQuery();

    conn.Close();
    string display = "Booking Details is added successfully";
