hello community, i was wondering if someone have the same error i have using the editor template for dates in ajax binding and editing.

System.InvalidCastException: not possible to associate object type 'System.Collections.Generic.List`1[My DTO]' to type 'System.IConvertible'.

this is my configuration:

DTO:

                    namespace SIG.DomainModel.Entities         
            {         
                [MetadataType(typeof(EmentaMetadata))]         
                public partial class Ementa         
                {         
                            
                }         
                     
                public class EmentaMetadata         
                {         
                     
             	// Date Time property that is related to error and attribute to call editor template        
                    [DataType(DataType.Date)]         
                    public DataType data { get; set; }         
                     
                }         
            }         

controller action:

                     [GridAction]         
                    public ActionResult Create()         
                    { 
            	    //this returns a GridModel<DTO> 
                    
                        return View(ServiceLocator.Current.GetInstance<IEmentas>().GetAvailableEmentas());         
                    }         
                     
                           

view

            <%@ Import Namespace="Telerik.Web.Mvc" %>

                        .Toolbar(commands => commands.Custom().Text("Copy").Url("javascript:copyRow()"))         
                        .DataKeys(dataKeys => dataKeys.Add(o => o.id))         
                        .Columns(columns =>         
                        {         
                            columns.Bound(o => o.idUnidade).Title("Unidade(s)");         
                            columns.Bound(o => o.descricao);         
                            columns.Bound(o => o.data); // this is the property for date editor template that returns the error         
                            columns.Bound(o => o.idRefeicao);         
                            columns.Bound(o => o.id).Format(Html.ActionLink(" ", "EmentasPratos", new { idEmenta = "{0}" }, new { @class = "iconDetail" }).ToString()).Encoded(false).Title("Pratos").Width(10); ;         
                            columns.Command(commands => commands.Edit());         
                        })         
                        .DataBinding(dataBinding => dataBinding         
                            .Ajax()         
                                .Update("Update", "Ementas")         
                                .Select("Create", "Ementas")         
                                .Insert("Insert", "Ementas"))         
                        .Pageable()         
                        .Sortable()         
                        .Filterable()         
                        .Selectable()         
                        .Render();         
                %>         
                </div>         
                         
            <script type="text/javascript">         
                function copyRow() {         
                var $grid = $('#Grid');         
                var grid = $grid.data('tGrid');         
                var $selectedRow = $('#Grid').find('tr.t-state-selected');         
                if ($selectedRow.length) {         
                    (grid.addRow || grid.createRow).apply(grid);         
                   $selectedRow.find('td').each(function(i) {         
                        $grid.find('.t-edit-form tr td')         
                            .eq(i)         
                            .find('input,select')         
                            .val($(this).text());         
                    });         
                }         
            }         
            </script>         
                     
            </asp:Content>         

and finally the editor:

                    <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<DateTime>" %>         
                     
            <%= Html.Telerik().DatePicker()         
                    .Name(ViewData.TemplateInfo.HtmlFieldPrefix)         
                    .HtmlAttributes(new { id = ViewData.TemplateInfo.HtmlFieldPrefix + DateTime.Now.Millisecond.ToString(),         
                                          name = ViewData.TemplateInfo.HtmlFieldPrefix         
                    })         
                    .Value(Model > DateTime.MinValue? Model : DateTime.Today)         
            %>         

Someone knows what can be wrong? it works if i pass to server binding

best regards
