Как подключить MySQL к DevExpress ASPxScheduler без SqlDataSource

Question

У меня есть проект ASP.net, который я рассматриваю, и они хотят использовать MySQL.Я привык к SQL-серверу, но использование MySQL не должно быть проблемой.

Обычно элементу управления требуется привязать SqlDataSource, но он недоступен в MySQL (из других сообщений на этом сайте).

Как лучше всего соединить MySQL и DevExpress ASPxScheduler, чтобы можно было создавать встречи?

Answer 1

Почему бы не использовать ObjectDataSource и не написать уровень данных?Или используйте LLBLGen, я думаю, он отлично работает с MySQL.Единственное предостережение, которое я заметил, заключается в том, что драйверы MySQL ODBC и ADO имеют проблемы с метаданными.

Answer 2

В итоге я использовал objectdatasource и метод ObjectCreated и написал уровень данных для вставки записей в базу данных mysql.Я включил свой код на тот случай, если кому-то понадобится помощь с некоторой логикой.

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);
