In Razor allow HiddenFor to hold empty string

Question

I have a ViewModel defined like this:

public class ProfileSnapshotViewModel
{
    public Guid ProfileSnapshotId { get; set; }
    [Required(AllowEmptyStrings = true)]
    public string Salutation { get; set; }
    //...
    public bool IsActive { get; set; }
}

And my MVC is set like this:

<td class="Cell">
    @Html.HiddenFor(model => model.ProfileSnapshotId)
    @Html.HiddenFor(model => model.IsActive)
    @Html.HiddenFor(model => model.Salutation)
    //...

When I set up the model I set it up like this:

 return PartialView("_additionalreviewerrow",
            new ProfileSnapshotViewModel
            {
                IsActive = true,
                Salutation = ""
            });

However, my ModelState.IsValid continues to be false when submitting, saying 'Salutation is required'.

What can I do to ensure the HiddenFor is holding the empty string, and validation doesn't complain?

(This is part of a larger chunk of code, so if you think something else could be affecting it, please comment and I'll try to add it.)

if it's required then you cant have empty string.. if it can be empty then dont make it required.. if you want blanks in the database then add a default value of '' — JamieD77, Nov 11 '15 at 17:34

I think your model somewhere must indicate that field is required. If I'm understanding correctly this is my best guess, otherwise try model.IsActive.ToString() and see what happens. — Rich Bianco, Nov 11 '15 at 18:22
