Controller

public ActionResult Create()
{
   return View(new PageViewModel());
} 

[HttpPost]
public ActionResult Create(Page page)
{
   try
   {
      repPage.Add(page);
      repPage.Save();

      return RedirectToAction("Edit");
   }
   catch
   {
      return View(new PageViewModel());
   }
}

PageViewModel

public class PageViewModel
{
    public Page Page { get; set; }
    public List<Template> Templates { get; set; }

    private TemplateRepository repTemplates = new TemplateRepository();

    public PageViewModel()
    {
        Page = new Page();
        Templates = repTemplates.GetAllTemplates().ToList(); 
    }
}

Parts of my View

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Website.Models.PageViewModel>" %>

<%= Html.TextBoxFor(model => model.Page.Name, new { @style = "width:300px;" })%>

<%= Html.DropDownListFor(model => model.Page.Template, new SelectList(Model.Templates, "ID", "Name"), new { @style = "width:306px;" })%>

Template:
ID
Name
Page:
ID
Name
TemplateID

My dropdownlist is populated correctly in the view, no problems there. My problem is that I dont get the selected value from the dropdownlist.

In my controller I i put a breakpoint in Edit and see that the Name textbox is populated with the value I type into it. But the selected from the dropdownlist is set to null.

Am I missing something, I thought it should set the correct Template value into the Page object. What am I doing wrong?

    The only thing that you get back from the web page is the id of the selected template. The default model binder doesn’t know how to take this id and retrieve the correct template object from your repository. To do this you would need to implement a custom model binder that is able to retrieve the values from the database, construct a Template object, and assign it to the Page. Or… you could do this manually in the action given that, according to your comments elsewhere, you know how to get the template’s id from the posted values.
