Question

This is the controller:

public ActionResult Index()
{

   var result = from u in myContext.Users
             join g in myContext.Groups
             on u.gid equals g.id
             select new {
                 u.username,
                 g.name
             };

   return View(result );
}

This is the View

@model IEnumerable<eTravel1.Models.User>
...
@Html.DisplayNameFor(model => model.username)
@Html.DisplayNameFor(model => model.name)
..

The returned anonymous data is not compatible in the View.
I would really apreciate it if someone could give some advice. Thanks

You should create a ViewModel Class like this:

public class UserViewModel{

    //class constructor
    public UserViewModel(String userName_p, String name_p){
         this.UserName = userName_p;
         this.Name = name_p;
    }

    //class attributes
    String UserName {get; set;}
    String Name {get; set;}
}

Create an object of that class:

var result = from u in myContext.Users
                 join g in myContext.Groups
                 on u.gid equals g.id
                 select new UserViewModel(
                     u.username,
                     g.name
                 );

And finally, pass this object to your view the same way:

//returning an IEnumerable<UserViewModel> data type
return View(result.AsEnumerable());

In your View, you should expect this exact same data type:

//change the UserViewModel to your complete namespace!
@model IEnumerable<UserViewModel>

I strongly recommend you to read this stackoverflow question about the “ViewModel Best Practices”.

Hope it helps!
