No validation errors are being displayed on Grid

[James Lam]

When I edit or insert a new row, I don't get feedback when an update/insert fails.  Any help would be appreciated.

My grid code looks like the following:

<asp:Content ContentPlaceHolderID="MainContent" runat="server">
<div style="margin: 10px 0px;">Article - Grid View</div>
<%= Html.Telerik().Grid<Article>()
        .Name("Grid")
        .DataKeys(keys => keys.Add(p => p.article_id))
        .ToolBar(commands => commands.Insert())
        .DataBinding(dataBinding => dataBinding.Ajax()
            .Select("_SelectAjaxEditing", "ArticleGridView")
            .Insert("_InsertAjaxEditing", "ArticleGridView")
            .Update("_SaveAjaxEditing", "ArticleGridView")
            .Delete("_DeleteAjaxEditing", "ArticleGridView"))
        .Columns(columns =>
        {
            columns.Bound(p => p.CategoryInitials).Title("Cat");
            columns.Bound(p => p.description).Width(130);
            columns.Bound(p => p.ColorName);
            columns.Bound(p => p.Cash);
            columns.Bound(p => p.registration_number).Title("Article #");
            columns.Bound(p => p.route);
            columns.Bound(p => p.BinName);
            columns.Bound(p => p.DivisionName);
            columns.Bound(p => p.DateLost);
            columns.Command(commands =>
            {
                commands.Edit();
            }).Title("Commands");
        })
        .Pageable(p => { p.PageSize(20); })
%>

<%= Html.Telerik().ScriptRegistrar() %>
</asp:Content>

My controller looks like the following:

[HttpPost]
[GridAction]
public ActionResult _SaveAjaxEditing(int id, FormCollection collection)
{
   var article = Article.Load(id);

   if (!string.IsNullOrEmpty(collection["description"])) {
      article.description = collection["description"];
   } else {
      ModelState.AddModelError("description", "description cannot be empty.");
   }
   article.ColorName = collection["ColorName"];
   article.cash = collection["cash"];
   article.registration_number = collection["registration_number"];
   article.route = collection["route"];
   article.BinName = collection["BinName"];
   article.DivisionName = collection["DivisionName"];

   DateTime d;
   if (DateType.TryParse(collection["date_lost"], d)) {
      article.date_lost = collection["date_lost"];
   } else {
      ModelState.AddModelError("date_lost", "invalid date.");
   }

   article.Save();

   return View(new GridModel(Article.FetchAll()));
}

(TryUpdateModule method keeps throwing an "An item with the same key has already been added." exception, so that's why I'm not using it.)
