I hope you find it helpfull !!

i use ViewBag For Project and Model for task so in this way i am using two model in single view and in controller i defined viewbag's value or data

List<tblproject> Plist = new List<tblproject>();
            Plist = ps.getmanagerproject(c, id);

            ViewBag.projectList = Plist.Select(x => new SelectListItem
            {
                Value = x.ProjectId.ToString(),
                Text = x.Title
            });

and in view tbltask and projectlist are my two diff models

@{

IEnumerable<SelectListItem> plist = ViewBag.projectList;

} @model List

Another option which doesn't have the need to create a custom Model is to use a Tuple<>.

@model Tuple<Person,Order>

It's not as clean as creating a new class which contains both, as per Andi's answer, but it is viable.

Answer 3

ok, everyone is making sense and I took all the pieces and put them here to help newbies like myself that need beginning to end explanation.

You make your big class that holds 2 classes, as per @Andrew's answer.

public class teamBoards{
    public Boards Boards{get; set;}
    public Team Team{get; set;}
}

Then in your controller you fill the 2 models. Sometimes you only need to fill one. Then in the return, you reference the big model and it will take the 2 inside with it to the View.

            TeamBoards teamBoards = new TeamBoards();


        teamBoards.Boards = (from b in db.Boards
                               where b.TeamId == id
                               select b).ToList();
        teamBoards.Team = (from t in db.Teams
                              where t.TeamId == id
                          select t).FirstOrDefault();

 return View(teamBoards);

At the top of the View

@model yourNamespace.Models.teamBoards

Then load your inputs or displays referencing the big Models contents:

 @Html.EditorFor(m => Model.Board.yourField)
 @Html.ValidationMessageFor(m => Model.Board.yourField, "", new { @class = "text-danger-yellow" })

 @Html.EditorFor(m => Model.Team.yourField)
 @Html.ValidationMessageFor(m => Model.Team.yourField, "", new { @class = "text-danger-yellow" })

And. . . .back at the ranch, when the Post comes in, reference the Big Class:

 public ActionResult ContactNewspaper(teamBoards teamboards)

and make use of what the model(s) returned:

string yourVariable = teamboards.Team.yourField;

Probably have some DataAnnotation Validation stuff in the class and probably put if(ModelState.IsValid) at the top of the save/edit block. . .

Another way that is never talked about is Create a view in MSSQL with all the data you want to present. Then use LINQ to SQL or whatever to map it. In your controller return it to the view. Done.

Answer 5

you can't declare two model on one view, try to use Html.Action("Person", "[YourController]") & Html.Action("Order", "[YourController]").

Good luck.

Answer 6

To use the tuple you need to do the following, in the view change the model to:

@model Tuple<Person,Order>

to use @html methods you need to do the following i.e:

@Html.DisplayNameFor(tuple => tuple.Item1.PersonId)

or

@Html.ActionLink("Edit", "Edit", new { id=Model.Item1.Id }) |

Item1 indicates the first parameter passed to the Tuple method and you can use Item2 to access the second model and so on.

in your controller you need to create a variable of type Tuple and then pass it to the view:

    public ActionResult Details(int id = 0)
    {
        Person person = db.Persons.Find(id);
        if (person == null)
        {
            return HttpNotFound();
        }
        var tuple = new Tuple<Person, Order>(person,new Order());

        return View(tuple);
    }
