                                     select new SelectListItem
                                     {
                                         Text = m.CUSIP.ToString(),
                                         Value = m.CUSIP.ToString()

            return cusipID.ToList();
        }

Home.controller
public ActionResult Index()
        {
            SecurityIdentifierMapping objModel = new SecurityIdentifierMapping();
            objModel.PricingSecurityID = objRepository.GetPricingSecurityID();
            objModel.CUSIP = objRepository.GetCUSIP();
            return View(objModel);
        }

public partial class SecurityIdentifierMapping
    {
        public int Id { get; set; }

        [Required(ErrorMessage = "Please select a PricingSecurityID")]
        public Nullable<int> PricingSecurityID { get; set; }

        [Required(ErrorMessage = "Please select a CUSIPID")]
        public string CUSIP { get; set; }

        public string Calculation { get; set; }
    }

tried AsEnumerable() also what to change?

Answer 1

I can’t be certain without seeing the definition for SecurityIdentiferMapping, but I’m going to guess that PricingSecurityID is of type int?. You are trying to set the return value of GetPricingSecurityID() to this property, but the return value of that method is List<SelectItemList>

Change your GetPricingSecurityID() method to return an int? or your property to accept a List<SelectItemList>.
