Binding models to view

I would like to Bind two models (say ModelA and Mode开发者_运维问答lB classes) to a view.ascx page. And each of these classes have List objects that I would like to access in view. I know we can access one class by associating strongly typed model to one of the classes. How do I bind the other class?

---

Simply create a ViewModel - class containing all models you need (in this case ModelA and ModelB). Then bind the view to this ViewModel and access it like model.ModelA.Property in your view.

Edit: You wrote that both ModelA and modelB has their collections? So you create something like:

public class ABViewModel
{
    public ModelA A {get;set;}
    public ModelB B {get;set;}
}

Then instantiate it in controller like:

ABViewModel abvm = new ABViewModel();
abvm.A = new ModelA();
abvm.B = new ModelB();

And return your view (strongly typed to ABViewModel).

return View(abvm);

And access your properties in View:

foreach (var item in model.A.CollectionProperty) // something like this

Or

model.B.Property // something like this

Ie. you can access both .. ModelA and ModelB, because they are now properties of another object - your new model.

Note: I am not sure, if you use model. or Model. in mvc2 to acces your model. It's model in mvc3.

You write a third class wrapping those two lists:

public class MyViewModel
{
    public IList<Foo> List1 { get; set; }
    public IList<Bar> List2 { get; set; }
}

and then you use this class as a view model passed to the view. Then inside the view you can access both lists:

<% foreach(var item in Model.List1) { %>
    ...
<% } %>

<% foreach(var item in Model.List2) { %>
    ...
<% } %>
