                     where s.VN_IsSpetial == false
                     where s.VN_OutOfDate == null
                     select new VisitCreatorViewModel()
                     {
                         DateStart = DateTime.MinValue,
                         RameId = 0,
                         RameTypeId = 0,
                         VisitNameId = s.VN_ID,
                         VisitName = s.VN_Name
                     }).ToList();
            return View(r);
        }
 
        [HttpPost]
        public ActionResult Create(List<VisitCreatorViewModel> results)

@model IEnumerable<Gestion_Prod_Web.Models.VisitCreatorViewModel>
@{
    Layout = null;
}
@using (Html.BeginForm())
{
    foreach (var item in Model)
    {
    <div class="ui-widget" style="float: left;width: 300px; margin:5px;">
        <div class="ui-dialog-titlebar ui-widget-header">
            <span id="ui-id-1" class="ui-dialog-title">@item.VisitName</span>
        </div>
        <div class="editor-label">
            @Html.LabelFor(model => item.RameTypeId)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => item.RameTypeId)
            @Html.ValidationMessageFor(model => item.RameTypeId)
        </div>
        <div class="editor-label">
            @Html.LabelFor(model => item.RameId)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => item.RameId)
            @Html.ValidationMessageFor(model => item.RameId)
        </div>
        <div class="editor-label">
            @Html.LabelFor(model => item.DateStart)
        </div>
        <div class="editor-field">
            <input type="text" class="datepicker" />
        </div>
    </div>
 
    }
    <p>
        <input type="submit" class="ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only" value="Save" />
    </p>
 
}

Apres avoir rempli le formulaire je reçoit un résultat null.
Quelqu'un saurait d'ou vient l'erreur ?
Merci.
