MVC Accessing navigation property for listboxFor - asp.net-mvc

Question

At first I should say i am compeletely newbie in MVC.
I have 3 Objects
public partial class Magazine
{
public Magazine()
{
this.NumberTitles = new HashSet<NumberTitle>();
}
public int Id { get; set; }
public int MagYear { get; set; }
public int MagNo { get; set; }
public int MagSeason { get; set; }
public string MagYear2 { get; set; }
public virtual ICollection<NumberTitle> NumberTitles { get; set; }
}
public partial class NumberTitle
{
public NumberTitle()
{
this.Articles = new HashSet<Article>();
}
public int Id { get; set; }
public int MagazineId { get; set; }
public int TitleId { get; set; }
public int position { get; set; }
public virtual ICollection<Article> Articles { get; set; }
public virtual Magazine Magazine { get; set; }
public virtual Title Title { get; set; }
}
public partial class Title
{
public Title()
{
this.ChildrenTitle = new HashSet<Title>();
this.NumberTitles = new HashSet<NumberTitle>();
}
public int Id { get; set; }
public string TitleText { get; set; }
public Nullable<int> ParentId { get; set; }
public virtual ICollection<Title> ChildrenTitle { get; set; }
public virtual Title ParentTitle { get; set; }
public virtual ICollection<NumberTitle> NumberTitles { get; set; }
}
In a View I want to have TextBox to show Magazine Number and 2 List boxes. one shows all the Available Titles and the Other just selected Titles for that Magazine Number.So I have made View Model
public class NumberTitleViewModel
{
public Magazine Magazine { get; set; }
public List<NumberTitle> NumberTitles { get; set; }
}
this is in controller. how can i get the list of titles for specified MagazineId
public ActionResult EditTitle(int id)
{
Func<IQueryable<Magazine>, IOrderedQueryable<Magazine>> orderByFunc = null;
Expression<Func<Magazine, bool>> filterExpr = null;
if (id>0)
{
filterExpr = p => p.Id.Equals(id);
}
Magazine magazine = unitOfWork.MagazineRepository.Get(filter: filterExpr, orderBy: orderByFunc, includeProperties: "").SingleOrDefault();
NumberTitleViewModel numberTitleViewMode = new NumberTitleViewModel();
numberTitleViewMode.Magazine = magazine;
Expression<Func<NumberTitle, bool>> filterExpr2 = null;
if (id > 0)
{
filterExpr2 = p => p.MagazineId.Equals(id);
}
var numberTitles = unitOfWork.NumberTitleRepository.Get(filterExpr2, null, includeProperties: "Title").ToList();
var titles = unitOfWork.TitleRepository.Get(null, null, "");
numberTitleViewMode.NumberTitles = numberTitles; ///this part doesn't show the Titles. how should access the TitleName not Id
ViewBag.titles = new SelectList(titles, "Id", "TitleText");
return View("../Panel/Magazine/EditTitle", "_BasicLayout", numberTitleViewMode);
}

Answer 1

Not sure what you have in your view but you should have something like:
#using NameSpace.Models
#model NameSpace.Models.NumberTitleViewModel
Then you can do something like this in your view:
foreach (NumberTitles item in #Model)
{
<label>#item.Title.TitleText</label>
}
Not exact but should get you close to what you need
