Question

What is the best way to passing a controller parameter to a view? The parameter is not related to any model, so cant do strongly typed view.

Controller:

        public ActionResult DisplayParam(string id, string name)
    {
       return View();
    }

View:

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage" %>

<%@ Import NameSpace=”System.IO” %>
<%@ Import NameSpace=”System” %>
<%@ Import NameSpace=”System.Data” %>
<%@ Import NameSpace=”System.Web” %>
<%@ Import NameSpace=”System.Text” %>
<%@ Import Namespace=”MY.Controllers” %>

Controller Parameter

<div>
Controller Parameter id: @id
Controller Parameter name: @name
</div>

The best way is to use a view model:

public class MyViewModel
{
    public string Id { get; set; }
    public string Name { get; set; }
}

and then have your controller action populate this view model and pass it to the view, just like this:

public ActionResult DisplayParam(string id, string name)
{
    var model = new MyViewModel
    {
        Id = id,
        Name = name
    };
    return View(name);
}

and finally you would have your view strongly typed to this view model and use the information to display it:

<%@ Page 
    Language="C#" 
    Inherits="System.Web.Mvc.ViewPage<AppName.Models.MyViewModel>" 
%>
<div>
    Controller Parameter id: <%= Html.DisplayFor(x => x.Id) %>
    Controller Parameter name: <%= Html.DisplayFor(x => x.Name) %>
</div>

or if you were using the Razor view engine:

@model AppName.Models.MyViewModel
<div>
    Controller Parameter id: @Html.DisplayFor(x => x.Id)
    Controller Parameter name: @Html.DisplayFor(x => x.Name)
</div>
