ASP.NET MVC - View with multiple models

Question

I am trying to generate such HTML

    <form action="/some/process" method="post">         <input type="hidden" name="foo.a" value="aaa"/>         <input type="hidden" name="bar.b" value="bbb"/>         <input type="submit" />     </form> 

so it can be processed by this Action:

    public ActionResult Process(Foo foo, Bar bar)     {         ...     } 

Given the Action code

    public ActionResult Edit()     {         ViewData["foo"] = new Foo { A = "aaa" };         ViewData["bar"] = new Bar { B = "bbb" };          return View();     } 

what should I write in Edit.aspx view? I don't want to write names 'foo.a' and 'bar.b' manually.

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.
