Hello,

Here's the functionality I'd like to exploit: I've a class myClass and would like to iterate over a collection that contains all the properties of that class. I'd like to send the index of that collection along with the other data so that I can control the each sequence of the iteration.

Here's simplified versions of a Action method and View (I'll use the same action-view for that functionality).

1) Action

public ActionResult CreateHierarchy(int? index)
{

  if(index < PropertiesOfMyClass.Lenght)
  {
    //Other code omitted 

    ViewData["index"] = ((index == null) ? 1 : index++);

    Return View();  
  }
}

2)View

<% Using(Html.BeginForm()){%>      
   //Other Code omitted

   <% = Html.Hidden("Index", ViewData["index"])%>
   <input type = "submit" value = "Do someting"/>
 <%}%>

I've also placed this at the bottom of the page so that I can check the value of the index,

<% = ViewData["index"]%>

Unfortunately, its not working. I'm getting only the number 1. I'm missing something? such as a cast for the Viewdata? Should I write something like this:

<% = Html.Hidden("index", (int)ViewData["index"])%>

It's not working either

Thanks for helping
