Hi All,

I'm trying to bind my dropdownlist with the model class where it takes the values from my EF. I have the below code

public sealed class StoreRegistrationViewModel
    {
        public StoreRegistrationInfoModel StoreRegistrationAssociation { get; set; }    
    }


 public class StoreRegistration
    {
        public IList StoreIdentity { get; set; }
        public int StoreNumber { get; set; }
        public string StoreName { get; set; }
        public string City { get; set; }
        public Address StoreAddress { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string StorePhone { get; set; }
        public string EmailAddress { get; set; }
        public string VerifyEmailAAddress { get; set; }
        public string Comments { get; set; }
    }

[ActionName("Index")]
        public ActionResult StoreRegistration()
        {
            StoreRegistration s = new StoreRegistration();
            s.StoreIdentity = retailIdentityRepository.GetActiveRetailIdentities();
            //ViewBag.RetailIdentity = retailIdentityRepository.GetActiveRetailIdentities();
             return View("Index");
        }


@using Newtonsoft.Json;
@model Mol2.Website.Models.StoreRegistration.StoreRegistrationViewModel
@{
    ViewBag.Title = "Index";
}

@Html.DropDownList("retailIdentityDDL",x => x.StoreRegistrationAssociation.StoreIdentity, "Select")
                                @Html.ValidationMessageFor(x => x.StoreRegistrationAssociation.StoreIdentity)

I'm getting an exception unable to cast IList to IEnumerable i'm new to MVC

Any Suggesstions or help would be appreciated

0	You can't able to directly bind an List collection to the dropdown list, you have to assign the values using the "SelectList" class.

0	public class StoreRegistration { // this will hold the selected value public string Hour { get; set; } public IEnumerable<SelectListItem> Hours { get { return Enumerable .Range(0, 23) .Select(x => new SelectListItem { Value = x.ToString("00"), Text = x.ToString("00") }); } } } you could populate this view model inside the controller: public class HomeController: Controller { public ActionResult Index() { var model = new StoreRegistration { // Set the Hour property to the desired value // you would like to bind to Hour = DateTime.Now.Hour.ToString("00") }; return View(model); } } and in your view simply: @Html.DropDownListFor( x => x.Hour, new SelectList(Model.Hours, "Value", "Text") ) Bhuvan Self-Innovator, if this helps please login to Mark As Answer. \| Alert Moderator

public class StoreRegistration

{

    // this will hold the selected value

    public string Hour { get; set; }



    public IEnumerable<SelectListItem> Hours 

    { 

        get

        {

            return Enumerable

                .Range(0, 23)

                .Select(x => new SelectListItem {

                    Value = x.ToString("00"),

                    Text = x.ToString("00")

                });

        } 

    }

}

you could populate this view model inside the controller:



public class HomeController: Controller

{

    public ActionResult Index()

    {

        var model = new StoreRegistration

        {

            // Set the Hour property to the desired value

            // you would like to bind to

            Hour = DateTime.Now.Hour.ToString("00")

        };

        return View(model);

    }

}

and in your view simply:



@Html.DropDownListFor(

    x => x.Hour, 

    new SelectList(Model.Hours, "Value", "Text")

)
