ASP.NET MVC 2 strongly typed htmlhelper, indexes

public class Foo { public bool Checked {get;set;}}

View:

<viewdata model="Foo[] fooList" />
<for each="var f in fooList">
    ${Html.CheckBoxFor(x=>x[fIndex].Checked)}
</for>

Will output:

<input id="Checked" name="Checked" type="checkbox" value="true" />
<input name="Checked" type="hidden" value="false" />

<input id="Checked" name="Checked" type="checkbox" value="true" />
<input name="Checked" type="hidden" value="false" />

<input id="Checked" name="Checked" type="checkbox" value="true" />
<input name="Checked" type="hidden" value="false" />

Problem is that System.Web.Mvc.ExpressionHelper.GetExpressionText does not include index in id/name.

That leads to problems in case I want to add a label for every checkbox (because all id`s are the same).

Any ideas how to handle this properly?

From the MVC source=>

 while (part != null) {
            if (part.NodeType == System.Linq.Expressions.ExpressionType.MemberAccess) {
                MemberExpression memberExpressionPart = (MemberExpression)part;
                nameParts.Push(memberExpressionPart.Member.Name);
                part = memberExpressionPart.Expression;
            }
            else {
                //arghhhh... [index] != MemberAccess :(
                break;
            }
        }

From stackoverflow Arnis L.

• Use the CheckBoxFor overload that allows you to specify html attributes:

  CheckBoxFor(TModel)(HtmlHelper(TModel), Expression(Func(TModel, Boolean)), IDictionary(String, Object))
  

  For example,

  ${Html.CheckBoxFor(x => x[fIndex].Checked, new { id = "foo" + fIndex) })}
  

  Arnis L. : That's not **properly**. In this case - let me ask what's the benefit of `CheckBoxFor` 'strongly-typed' helper method if i won't be able to get that id back from view model without messing around with hard-coded strings? That's the same as to use `${Html.CheckBox("foo"+fIndex,m.AllCatalogs[i].Checked)}` which even looks better.

  Brettski : @Arnis L. Agreed

• The ability of the expression-based helpers to understand indexes isn't in the product yet. It will be in the next preview release (whatever comes after MVC 2 RC). See http://aspnet.codeplex.com/WorkItem/View.aspx?WorkItemId=4970.
