Hello! I’m having trouble with a contact form where I want a CheckBoxList. I'm using the mvccbl extencion [http://mvccbl.com/].

I want the user to check at least one from the list. When you do that, but doesn't fill in the other fields and submit, the server validates the form. Since the name and email is required the form returns invalid. But now the page doesn't remember the one which is selected from the list.
Also the unobtrusive validation dosent kick in at the cbl???

This can be seen on www4.etlgroup.dk/privat/kontakt-os/

So far I have:

Omraade.cs

public class Omraade {
        public int Id { get; set; }
        public string Name { get; set; }
        public object Tags { get; set; }
        public bool IsSelected { get; set; }
    }

ContactModel.cs

public class ContactModel{
        public IList<Omraade> AvailableOmraader { get; set; }
        public IList<Omraade> SelectedOmraader { get; set; }
        [BooleanRequired(ErrorMessage = "Du skal vælge mindst et område.")]
 public PostedOmraader PostedOmraader { get; set; }
        [Required(ErrorMessage = "Dette felt er påkrævet.")]
  [Display(Name = "Navn")]
 public string Name { get; set; }
        [Required(ErrorMessage = "Dette felt er påkrævet.")]
 [RegularExpression(@"^[a-zA-Z0-9.!#$%&'*+\/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$", ErrorMessage = "Indtast en gyldig email-adresse.")]
   [Display(Name = "E-mail")]
 public string Email { get; set; }
        [Display(Name = "Telefonnummer")]
 public string Phone { get; set; }
        [Display(Name = "Evt. kommentar")]
 public string Message { get; set; }
        public IHtmlString SuccesMsg { get; set; }
        public IHtmlString ErrorMsg { get; set; }
    }
    //Helper Class to make posting back selected values easier
    public class PostedOmraader{
   public string[] OmraaderIDs { get; set; }
    }
}

ContactSurfaceController.cs

public class ContactSurfaceController : SurfaceController {
        public ActionResult RenderContactForm(){
            var omraader = Umbraco.Field("omraader").ToString().Split(',');
            ListOmraade> OmraaderList = new ListOmraade>();
            for (int i = 0; i <= omraader.Length - 1; i++){
                OmraaderList.Add(new MvcEltGroup.Logic.Omraade { Name = omraader[i], Id = i });
            }
            return PartialView("/Views/Partials/Forms/ContactForm.cshtml", new ContactModel {  
                AvailableOmraader = OmraaderList,
                ErrorMsg = Umbraco.Field("errorMsg"),
                SuccesMsg = Umbraco.Field("successMsg")
            });
        }
 
        [HttpPost]
 [ValidateAntiForgeryToken]
    public ActionResult HandleContactForm(ContactModel model) {
            if (!ModelState.IsValid){
                return CurrentUmbracoPage();
            }
            try {
                StringBuilder sb = new StringBuilder();
                sb.AppendFormat("Name: {0}", model.Name);
                sb.AppendFormat("Email: {0}", model.Email);
                sb.AppendFormat("Phone: {0}", model.Phone);
                sb.AppendFormat("{0}", model.Message);
                library.SendMail(model.Email, "[email protected]", "Kontakt hjemmesiden", sb.ToString(), true);
                TempData["IsSuccessful"] = true;
            }catch (Exception ex){
                TempData["IsError"] = ex.ToString();
            }
            return CurrentUmbracoPage();
        }
    }
