ASP.net MVC - rendering a List containing different types, with a different view for each type

Question

Imagine I have a list of objects that implement an interface called ISummary The objects within this list MAY have additional properties ie.

public interface         


        

Answer 1

I'd create an HtmlHelper extension that did this. Here's some pseudocode that looks shockingly like c# and may actually work:

public static void TemplatedList(this HtmlHelper me, IEnumerable items, 
IDictionary> templates)
{
  foreach(var item in items)
  {
    var template = templates[item.GetType()];
    if(template != null) template(item);
  }
}

I'd use it like this:

<% HtmlHelper.TemplatedList(ViewData.Model, new Dictionary
  {
    {typeof(GigSummary), x => %>


SUP!  GIG ANNOUNCEMENT FOR <%= x.Band %>!!

What:  <%= x.Title %>
When: <%= x.Created %>
Who: <%= x.Author %>


    <%}
  // add more type/template pairs here
  }); %>
