Question

I’m starting to use DataAnnotations in ASP.NET MVC and strongly typed template helpers.

Now I have this in my views (Snippet is my custom type, Created is DateTime):

 <tr>
  <td><%= Html.LabelFor(f => Model.Snippet.Created) %>:</td>
  <td><%= Html.EditorFor(f => Model.Snippet.Created)%></td>
 </tr>

The editor template for DateTime is like this:

 <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.DateTime>" %>
 <%=Html.TextBox("", Model.ToString("g"))%>  

But now I want to put inside editor template the whole <tr>, so I’d like to have just this in my view:

 <%= Html.EditorFor(f => Model.Snippet.Created)%>

And something like this in editor template, but I don’t know how to render for for label attribute, it should be Snippet_Created for my example, the same as id\name for textbox, so pseudo code:

 <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.DateTime>" %>
 <tr>
  <td><label for="<What to place here???>"><%=ViewData.ModelMetadata.DisplayName %></label></td>
  <td><%=Html.TextBox("", Model.ToString("g"))%></td>
 </tr>

The Html.TextBox() have the first parameter empty and id\name for textbox is generated corectly.

Thanks in advance!

I found one solution here: Rendering the field name in an EditorTemplate (rendered through EditorFor())

But it seems a little verbose, may be it can be wrapped in custom Html Helper:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.DateTime>" %>
<tr>
    <td>
        <label for="
            <%= ViewData.TemplateInfo.HtmlFieldPrefix.Replace(
                    ".", 
                    HtmlHelper.IdAttributeDotReplacement) 
            %>">
            <%= ViewData.ModelMetadata.DisplayName %>:
        </label>
    </td>
    <td>
        <%= Html.TextBox("", Model.ToString("g")) %>
    </td>
</tr>
