Question

I have an MVC2 view which is strongly bound to a model.

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<System.Collections.Generic.IEnumerable<AdjustmentModel>>" %>

And in the View I have.

         foreach (var adjustment in Model)
           {%>
         <tr row="<%: row %>">
            <td class="nonSelectable" column="0">
                <div>
                    ...I want to put a textbox here that has name="someId" 
                   and val="someVal" but how?
                </div>
            </td>

            }%>

The model is

class AdjustmentModel
{
    public int ID;
    public int amount;
}

I just can’t figure the delegate that I pass to Html.TextBoxFor() because when I pass a model the intellisense won’t work as I’m passing in an Ienumerable so how do I use the model?

I would recommend you using editor templates. This way you don’t need to write any loops and still keep the strong typing:

<table>
    <%= Html.EditorForModel() %>
</table>

and then you define an editor template which will be automatically rendered for each element of your collection (~/Views/Shared/EditorTemplates/AdjustmentModel.ascx):

<%@ Control 
    Language="C#" 
    Inherits="System.Web.Mvc.ViewUserControl<AdjustmentModel>" 
%>
<tr>
    <td class="nonSelectable" column="0">
        <div>
            <%= Html.HiddenFor(x => x.ID) %>
            <%= Html.EditorFor(x => x.amount) %>
        </div>
    </td>
</tr>

It is important to respect the convention which is to locate your editor template inside the ~/Views/CurrentController/EditorTemplates or ~/Views/Shared/EditorTemplates folder. The name of the template must be the type used in the collection. So for example if you have IEnumerable<AdjustmentModel>, the file must be called AdjustmentModel.ascx and obviously strongly typed to AdjustmentModel. This template will then be automatically called for each element.
