asp.net mvc - MVC5 Scaffolding Dropdowns Out the Box -


i want view, edit , create drop-down list of lookup relationships.

sometimes works, doesn't. it's mystery i'm hoping can solved here.

here's poco's lookup

public class color {      public int id { get; set; }      public string value {get;set;} }  //red,white,blue  public class size {      public int id { get; set; }      public string value { get; set; } }  //s,m,l

and here main object i'd have color , size drop-downs scaffolding out of box.

public class product {     public int id;     public string name;     public virtual color color;     public virtual size size; }

this isn't working me. neither size or color showing when it's time view, edit or create product. see name field.

size , color lazy loaded default (virtual) need eagerly load them:

var products = context.products.include(p => p.color).include(p => p.size).tolist();

if issue drop downs, want compose viewmodel in controller has list items, send view , use dropdownlistfor(m => m.colorid, m.colors). may need add colorid , sizeid product model. here explanation: http://odetocode.com/blogs/scott/archive/2013/03/11/dropdownlistfor-with-asp-net-mvc.aspx
