When passing the model to MVC you have a couple of options.
Option 1: Passing un-typed model to the view
public ActionResult Product(string id)
{
var product = new Product();
product.ID = id;
product.Name = "iPhone";
ViewData["product"] = product;
}
In your view you have to cast the value in ViewData to the correct type as follows:
<%
var item = (Product)ViewData["product"];
%>
<div>
ID: <%= item.ID %>
Name: <%= item.Name %>
</div>
Option 2: Pass a strongly typed model to the view
// ViewData["product"] = product;
ViewData.Model = product;
The Page directive of your view must specify the type it expects as follows:
<%@ Page Title="blah" ... Inherits="System.Web.Mvc.ViewPage<Product>" %>
Sometimes you may need to pass more than one object to the view. You can handle this by creating a new class that encapsulates all objects you need and pass an instance of that class to the view instead.
