How to edit multiple models in a single Razor View

You need to include the other ViewModels into a main CompositeModel like so

public class CompositeModel {
    public Album AlbumModel { get; set; }
    public Another AnotherModel { get; set; }
    public Other EvenMore { get; set; }
}

Send that to your view like so

public ActionResult Index() {
    var compositeModel = new CompositeModel();
    compositeModel.Album = new AlbumModel();
    compositeModel.OtherModel = new AnotherModel();
    compositeModel.EvenMore = new Other();        
    return View(compositeModel)
}

Modify your view to take the new model type

@model CompositeModel

To refer to properties of the sub-models you can use syntax like this

@Html.TextBoxFor(model => model.Album.ArtistName)

or you can create a view in the EditorTemplates folder that takes a sub-model like AlbumModel and use EditorFor like this

@Html.EditorFor(model => model.Album)

The template would look something like this

@model AlbumModel

@Html.TextBoxFor(model => model.AlbumName)
@Html.TextBoxFor(model => model.YearReleased)
@Html.TextBoxFor(model => model.ArtistName)

Now just post CompositeModel back to your controller and then save all the sub-models and now Bob’s your uncle!

[HttpPost]
public ActionResult Index(CompositModel model) {
    // save all models
    // model.Album has all the AlbumModel properties
    // model.Another has the AnotherModel properties
    // model.EvenMore has the properties of Other
}
