@Html.LabelFor(model => model.date, htmlAttributes: new { @class = "control-label col-md-2" })
            
                @Html.EditorFor(model => model.date, new { htmlAttributes = new { @class = "form-control", id = "datepicker" } })
                @Html.ValidationMessageFor(model => model.date, "", new { @class = "text-danger" })
            
        

 
                @Html.LabelFor(model => model.time, htmlAttributes: new { @class = "control-label col-md-2" })
                
                    @Html.DropDownList("time", null, "--Select Time--", htmlAttributes: new { @class = "form-control" })
                    @Html.ValidationMessageFor(model => model.time, "", new { @class = "text-danger" })

    {

        return View();

    }

    // POST: Booking/Create

    [HttpPost]

    public ActionResult CreateBooking(bookingPatient bo)

    {

        try

        {

            b.booking(bo);

            System.Web.HttpContext.Current.Session["date"] = bo.date;

            return RedirectToAction("Index", "Booking");


        }

        catch

        {

            return View();

        }

    }

this is my business class

public void booking(bookingPatient model)
    {
        using (var bookpro = new BookingRepository())
        {
            if (model.BookingId == 0)
            {
                Booking _booking = new Booking
                {
                    Date = model.date,
                    Time = model.time                        
                };
                bookpro.Insert(_booking);
                System.Web.HttpContext.Current.Session["bookingId"] = _booking.BookingId;
            }
        }
    }

this is my modelview

public class bookingPatient
{
    public int id { get; set; }
    public DateTime date{ get; set; }
    public DateTime time { get; set; }
}

Someone please guide me in this regard. Thanks in advance
