Question

I have a view that uses a strongly typed ViewData similar to this:

namespace Site.web2.Models {     public class MySubData     {         public string Note { get; set; }         public bool IsValid { get; set; }     }     public class MyViewData     {         public int DataId { get; set;}         public List<MySubData> SubData { get; set; }          public MyViewData()         {         }          public void LoadDummyData()         {             DataId = 42;             SubData = new List<MySubData>();             SubData.Add(new MySubData() { Note = 'Item 1' });             SubData.Add(new MySubData() { Note = 'Item 2' });         }     } } 

Controller:

[AcceptVerbs(HttpVerbs.Get)] public ActionResult Test1() {     Site.web2.Models.MyViewData data = new Site.web2.Models.MyViewData();     data.LoadDummyData();     return View(data); }  [AcceptVerbs(HttpVerbs.Post)] public ActionResult Test1(Site.web2.Models.MyViewData data) {     return RedirectToAction('Index'); } 

And the View is like this:

<%@ Page Title='' Language='C#' MasterPageFile='~/Content/Site.Master'      Inherits='System.Web.Mvc.ViewPage<Site.web2.Models.MyViewData>' %> <%= Html.BeginForm<HomeController>(c => c.Test1(null)) %> <p>Id:</p> <p><%= Html.TextBox('DataId')%></p> <p>Note 1:</p> <p><%= Html.TextBox('SubData[0].Note')%></p> <p>Note 2:</p> <p><%= Html.TextBox('SubData[1].Note')%></p>  <input type='submit' value='Submit' /> <% Html.EndForm(); %> 

Ok, if I create a MyViewData, call LoadDummyData(), and use that in a View, I don’t see my data in the TextBoxes.

The funny thing is, if I enter data in to the TextBoxes, that will get populated into the returned MyViewData in the Post controller.

What am I doing wrong? Was this fixed in a later version of MVC? I think I have RC 1.

Update 1

This

<%= Html.TextBox('DataId')%> 

works just fine. I guess my question is, should this

<%= Html.TextBox('SubData[0].Note')%> 

work the same way?

Try this:

<p>Id:</p> <p><%= Html.TextBox('DataId', Model.DataId)%></p> <p>Note 1:</p> <p><%= Html.TextBox('SubData[0].Note', Model.SubData[0].Note)%></p> <p>Note 2:</p> <p><%= Html.TextBox('SubData[1].Note', Model.SubData[1].Note)%></p>
