Controller (GetAll return a IList)

newViewModel.Sites = siteRepository.GetAll();

View

@Html.DropDownListFor ?

I need to display a dropdown with some properties of the list items. Id and Url are some properties of these items in the list.

Answer 1

It worked!

ViewModel

public IEnumerable<SelectListItem> Sites {get; set;}
public string SiteSelected {get; set;}

Controller

private IEnumerable<SelectListItem> GetAllSites()
{
    return context.SITE.Select(x => new SelectListItem
    {
        Text = x.NAME,
        Value = SqlFunctions.StringConvert((double)x.ID).Trim()
    }).ToList();
}

siteViewModel.Sites = GetAllSites();

View

@Html.DropDownListFor(model => model.SiteSelected , Model.Sites)

You need to modify it to appropriately work with an IList but it is a small code change.
