This is my ViewModel: ``` public class CandidateViewModel{    public string Name { get; set; }    public IList Courses { get; set; }    public CandidateViewModel()    {        Name ="Kiwanax";        Courses = new List();        for (int count = 0; count < 5; ++count)        {            Courses.Add(new CourseViewModel(                 string.Format("Course_{0}", count), 5));        }    } }public class CourseViewModel{    public long ID {get; set; }    public string Name{ get; set; }    public OptionViewModel SelectedOption { get; set; }    public IList Options { get; set; }    public CourseViewModel(string name, int numberOfOptions)     {        Name = name;        Options = new List();        for (int count = 1; count <= numberOfOptions; ++count)        {            Options.Add(new OptionViewModel(count.ToString(),                 string.Format("Option {0}", count)));        }        SelectedOption = Options[0];    }}public class OptionViewModel{    public string Value { get; set; }    public string Description { get; set; }} ``` ``` OK. When I create DropDownLists based on my IList, it works fine.
    @for (int count = 0; count < Model.Courses.Count; ++count){    
  •         @Html.DropDownListFor(i => i.Courses[count].SelectedOption,            new SelectList(Model.Courses[count].Options, "Value", "Description", Model.Courses[count].SelectedOption))                @Html.HiddenFor(i => i.Courses[count].ID)      @Model.Courses[count].Name           
    •         }       
``` But, when I do [post](https://www.mindstick.com/articles/12829/aspects-that-make-australia-post-shipping-extension-a-useful-tool) from my form, I'm getting null values from that IList. ## Replies ### Reply by Pravesh Singh Hi Takeshi, You cannot bind dropdowns to complex property [values](https://www.mindstick.com/forum/327/sum-textbox-values): i => i.Courses[count].SelectedOption It must be bound to the corresponding primitive type that will be sent to the server: i => i.Courses[count].SelectedOption.Value Remember that in HTML the
