ASP.NET MVC – View with multiple models

by

String-indexed ViewData is bad. What you probably want to do is make a little wrapper class for your multi-variable view data and pass that to a strongly typed view. IE:

public class FooBarViewData
{
   public Foo Foo {get; set;}
   public Bar Bar {get; set;}
}
public ActionResult Edit()
{
   FooBarViewData fbvd = new FooBarViewData();
   fbvd.Foo = new Foo(){ A = "aaa"};
   fbvd.Bar = new Bar(){ B = "bbb"};
   return View(fbvd);
}

Then your view is just strongly typed to FooBarViewData and you can call members of that object using the Model property.
