Как предварительно заполнить TexboxFor из базы данных MVC

Question

У меня есть таблица внутри формы, которая выглядит следующим образом

Что я хочу сделать, это когда пользователь выбирает День и нажимает Search минуты Текстовое поледолжны заполняться минутами, соответствующими каждому SID.

Моя модель

 public class InsertedMinutes
{
    public string SID { get; set; }

    public string FullName { get; set; }

    public string Minutes { get; set; }

    public string ClassID { get; set; }

    public DateTime Date { get; set; }

}

Мой контроллер

public class ClassController : Controller
{
    DAL.DB dblayer = new DAL.DB();

    public ActionResult Class(ClassModel ClassModel, string datepicker)
    {
        List<ClassModel> students = dblayer.GetClass(ClassModel.InstructorSID, ClassModel.StartTime);
        var InsSID = ClassModel.InstructorSID;
        var time = ClassModel.StartTime;
        ViewBag.InstructorSID = InsSID;
        ViewBag.StartTime = time;

        return View(students);
    }

    [HttpPost]
    public ActionResult Index(List<ClassModel> students, string datepicker)
    {
        DateTime Date = DateTime.ParseExact(datepicker, "MM/dd/yyyy", null);
        //ClassModel s = new ClassModel();
        //ViewData["InstructorSID"] = s.InstructorSID;

        TryUpdateModel(students);
        if (ModelState.IsValid)
        {
            DB classes = new DB();
            string msg = classes.Minutes(students, Date);
            //TempData["Message"] = msg;
            ViewData["Message"] = "Minutes Inserted";
        }

        return View();
    }

    public InsertedMinutes Update (string datepicker, string ClassID)
    {
        ClassModel s = new ClassModel();
        ClassID = s.ClassID;

        DateTime Date = DateTime.ParseExact(datepicker, "MM/dd/yyyy", null);

        return new DB().Getminutes(Date, ClassID);        
    }        
}

Для моего класса InsertedMinutes Метод обновления, который являетсятот, который должен получить и заполнить мое Textbox, в моей БД у меня есть эта логика

 //GET Minutes for Instructor View
    public InsertedMinutes Getminutes(DateTime Date, string ClassID)
    {
        InsertedMinutes s = new InsertedMinutes();
        string connectionString = ConfigurationManager.ConnectionStrings["ABEAttendanceDB"].ConnectionString;
        using (SqlConnection myConnection = new SqlConnection(connectionString))
        {
            SqlCommand myCommand = new SqlCommand("[sp_ABEAttendanceGetMinutes]", myConnection);
            myCommand.CommandType = CommandType.StoredProcedure;
            SqlParameter DateParam = myCommand.Parameters.Add("Date", SqlDbType.Bit);
            DateParam.Value = Date;

            SqlParameter ClassIDParam = myCommand.Parameters.Add("ClassID", SqlDbType.Bit);
            ClassIDParam.Value = ClassID;

            myConnection.Open();
            using (SqlDataReader oReader = myCommand.ExecuteReader())
            {
                while (oReader.Read())
                {                     
                    {
                        s.SID = SafeGetString(oReader, "SID");
                        s.FullName = SafeGetString(oReader, "FullName");
                        s.Minutes = SafeGetString(oReader, "Minutes");
                        s.Date = SafeGetDate(oReader, "Date");
                        s.ClassID = SafeGetString(oReader, "ClassID");

                    };                       
                }
                myConnection.Close();
            }
        }

        return s;
    }

Вот мой взгляд:

@model List<ABEAttendanceV3.Models.ClassModel>

@{
ViewBag.Title = "Class";
}

<script>
var date = new Date();
var maxdate = date.getDate();
$(function () {
    $("#datepicker").datepicker({
        defaultDate: maxdate,
        minDate: '-1M',
        maxDate: '+0D'
    });
   });

 </script>

 <div>
@using (Html.BeginForm("Class", "Class", new { InstructorSID = 
ViewBag.InstructorSID, StartTime = ViewBag.StartTime }))
{

    @Html.ValidationSummary(true)

В вашем опыте парней, что было бы лучшим способомсделать это?
