Question

Here’s what I’m trying to do :

I have an entity Task with a TaskName property and a TaskPriority property.

Now, in the html I have :

<td><%=Html.TextBox('Task.TaskName') %></td> <td><%=Html.DropDownList('Task.TaskPriority',new SelectList(ViewData.Model.TaskPriorities,'ID','PriorityName')) %></td> 

The Controller action is like this :

public ActionResult Create(Task task){     //task.TaskName has the correct value     //task.TaskPriority is null - how should the html look so this would work ? } 

EDIT In the example bellow (from Schotime) :

public class Task {     public int name { get; set; }     public string value { get; set; } // what if the type of the property were Dropdown ?        // in the example I gave the Task has a property of type: TaskPriority. }

This should work.

Three classes:

    public class Container     {         public string name { get; set; }         public List<Dropdown> drops { get; set; }     }      public class Dropdown     {         public int id { get; set; }         public string value { get; set; }     }      public class Task     {         public int name { get; set; }         public TaskPriority priority { get; set; }     }      public class TaskPriority     {         public string value { get; set; }         ...     } 

Controller:

    public ActionResult Tasks()     {         List<dropdown> ds = new List<Dropdown>();         ds.Add(new Dropdown() { id = 1, value = 'first' });         ds.Add(new Dropdown() { id = 2, value = 'second' });          ViewData.Model = new Container() { name = 'name', drops = ds };          return View();     }      [AcceptVerbs(HttpVerbs.Post)]     public ActionResult Tasks(Task drops)     {         //drops return values for both name and value         return View();     } 

View: Strongly typed Viewpage<Container>

<%= Html.BeginForm() %> <%= Html.TextBox('drops.name') %> <%= Html.DropDownList('drops.priority.value',new SelectList(ViewData.Model.drops,'id','value')) %> <%= Html.SubmitButton() %> <% Html.EndForm(); %> 

When i debugged it worked as expected. Not sure what you are doing wrong if you have something similar to this. Cheers.
