Question

So the link below outlines a problem with MVC 3 / unobtrusive validation with dropdown lists. Essentially client side validation script is not emitted for dropdown lists. Is there a straightforward workaround for this? I’m confused as to how MVC 3 was released like this when this bug was reported well before the final release. Is there a simple solution to this that’s surfaced while we wait for a fix?

Maybe I’m alone on this, but it seems validating ALL elements of a form is important. 🙂

DropDownListFor() Unobtrusive Validation Problem

Answer 1

It also seems to work fine for me

   <p>                                                         
       <p>
            <span class="lbl"> @Html.LabelFor(x => x.SelectedTimeZone, " Select a TimeZone: ")</span>
            <span>@Html.DropDownListFor(x => x.SelectedTimeZone, Model.TimeZones)</span>
            <span class="validation-error">@Html.ValidationMessageFor(x => x.SelectedTimeZone)</span>    
        </p>

// view model

  [Required(ErrorMessage = "Time zone is required")]
    public string SelectedTimeZone { get; set; }
    public SelectList TimeZones { get; set; }

    public SetupViewModel()
    {
        TimeZones = new SelectList(TimeZoneExtensions.BuildTimeZoneList(), "value", "text", "selected");
        SelectedTimeZone = "UTC";
    }
