Html.DisplayFor not posting values to controller in ASP.NET MVC 3

Question

I am using ASP.NET MVC 3 with Razor, below is a sample from my view code.

The user should be able to edit all their details, except the "EmailAddress" field. For that field only I have used Html.DisplayFor(m => m.EmailAddress).

But when this form gets posted, all the model properties are filled except the EmailAddress.

How do I get the email back in the model when posting? Should I have used some helper other than DisplayFor?

@using (Html.BeginForm()) {     @Html.ValidationSummary(true, "Account update was unsuccessful. Please correct any errors and try again.")     <div>         <fieldset>             <legend>Update Account Information</legend>             <div class="editor-label">                 @Html.LabelFor(m => m.EmailAddress)             </div>             <div class="editor-field">                 @Html.DisplayFor(m => m.EmailAddress)                 @*@Html.ValidationMessageFor(m => m.EmailAddress)*@             </div>                        <div class="editor-label">                 @Html.LabelFor(m => m.FirstName)             </div>             <div class="editor-field">                 @Html.TextBoxFor(m => m.FirstName)                 @Html.ValidationMessageFor(m => m.FirstName)             </div>             <div class="editor-label">                 @Html.LabelFor(m => m.LastName)             </div>             <div class="editor-field">             @Html.TextBoxFor(m => m.LastName)                 @Html.ValidationMessageFor(m => m.LastName)             </div>             <p>                 <input type="submit" value="Update" />                             </p>         </fieldset>     </div> } 

Please advise me on this.

Answer 1

you'll need to add a

@Html.HiddenFor(m => m.EmailAddress) 

DisplayFor won't send anything in POST, it won't create an input...

By the way, an

@Html.HiddenFor(m => m.Id) // or anything which is the model key

would be usefull
