Cómo conectar mysql a DevExpress ASPxScheduler sin SqlDataSource

Question

Tengo un proyecto ASP.net que estoy viendo y quieren usar MySQL. Estoy acostumbrado al servidor SQL, pero usar mySQL no debería ser un problema.

Normalmente, el control desea un enlace a SqlDataSource, pero no está disponible con MySQL (de otras publicaciones en este sitio).

¿Cuál es la mejor manera de conectar MySQL y DevExpress ASPxScheduler para que pueda crear citas?

Answer 1

¿Por qué no un ObjectDataSource y escribe la capa de datos? O use LLBLGen, creo que funciona bien con MySQL. La única advertencia que he visto es que los controladores ODBC y ADO de MySQL tienen problemas con los metadatos.

Answer 2

Terminé usando el objeto ObjectDatasource y el método ObjectCreated y escribí el archivo de datos para insertar registros en la base de datos mysql. He incluido mi código solo en caso de que alguien necesite ayuda con algo de lógica.

protected void appointmentsDataSource_ObjectCreated(object sender, ObjectDataSourceEventArgs e)
    {
        e.ObjectInstance = new CustomEventDataSource(GetCustomEvents());
    }

  public void InsertAppointment()
    {

        //need to reformat the dates
        string tempStartDate;
        string tempStartMinutes;

        if (appointmentobject.Start.Minute.ToString().Length == 1)
        {
            tempStartMinutes = "0" + appointmentobject.Start.Minute.ToString();
        }
        else
        {
            tempStartMinutes = appointmentobject.Start.Minute.ToString();
        }

        tempStartDate = AppointmentObject.Start.Year + "-"
            + AppointmentObject.Start.Month + "-"
            + appointmentobject.Start.Day + " "
            + appointmentobject.Start.Hour + ":"
            + tempStartMinutes;

        string tempEndDate;
        string tempEndMinutes;

        if (appointmentobject.End.Minute.ToString().Length == 1)
        {
            tempEndMinutes = "0" + appointmentobject.End.Minute.ToString();
        }
        else
        {
            tempEndMinutes = appointmentobject.End.Minute.ToString();
        }

        tempEndDate = AppointmentObject.End.Year + "-"
            + AppointmentObject.End.Month + "-"
            + appointmentobject.End.Day + " "
            + appointmentobject.End.Hour + ":"
            + tempEndMinutes;

        //TODO Add CustomField : Need to add to this Insert Statement

        //Change the appointment subject
        string NewSubject = AppointmentObject.CustomFields["fldFirstName"]
            + ", " + AppointmentObject.CustomFields["fldLastName"]
            + ", " + AppointmentObject.CustomFields["fldClassID"]
            + ", " + AppointmentObject.CustomFields["fldPhoneNumberDay"];

        string mySQLQueryString = @"INSERT INTO appointment (StartDate,EndDate,Subject,Status,Description,label,location,Type,FirstName,
            LastName,PhoneNumberDay,PhoneNumberEvening,DriversLicenseNumber,Email,RentalCar,Payment,ConfirmationNumber,
            PermitNumber,ClassID,CreateDate,CreateUser,NoticeToReport) 
            VALUES('" + tempStartDate + "','"
            + tempEndDate + "', '"
            //+ AppointmentObject.Subject + "',"

            + AppointmentObject.CustomFields["fldConfirmationNumber"] + "','"
            + AppointmentObject.CustomFields["fldPermitNumber"] + "',"
            + AppointmentObject.CustomFields["fldClassID"] + ", '"
            //ignore create date for now.
            //+ AppointmentObject.CustomFields["fldCreateDate"] + "', '"
            + "2009-01-01 12:00', '"
            + AppointmentObject.CustomFields["fldCreateUser"] + "', "
            + AppointmentObject.CustomFields["fldNoticeToReport"] + ")";

        MySqlConnections test = new MySqlConnections();
        test.InsertRow(mySQLQueryString);

    }

        adapter.Fill(dataset, tablename);

        conn.Close();

        conn.ConnectionString = DriverConnectionString;

        try
        {
            conn.Open();
            cmd.Connection = conn;
            cmd.CommandText = query;
            cmd.ExecuteNonQuery();
            conn.Close();
            Console.WriteLine("Success Occurred ");
        } //end of try
