[Solved] Grid dynamic Binding

[Yuliang]

Hi, I saw there was solution to bind the dynamic objects to Grid, but I used the solution to bind, it threw exception.
Code:
Html.Telerik().Grid<dynamic>(Model.Select(n => new { n.ID, n.ItemID, n.Title, n.Name, n.VersionID }).ToList())
                         .Name("Grid")
                         .ToolBar(f => f.Position(GridToolBarPosition.Both).Custom().Action("Add", "TelerikNews", null).Text("Add"))
                         .Columns(columns =>
                         {
                             columns.Bound("ItemID");
                             columns.Bound("VersionID");
                             columns.Bound("Name");
                             columns.Bound("Title");
                             columns.Template(n =>
                             {
                                 %>
                                    <%=Html.ActionLink("Edit", "Edit", new { id = ( n as dynamic) .ID })%>
                                    <%=Html.ActionLink("Delete", "Delete", new { id = (n as dynamic).ID }, new { onclick = "return confirm('Are you sure to delete this item?');" })%>
                                 <%
                             });
                         })
                         .PrefixUrlParameters(false)
                         .DataBinding(c => c.Server())
                         .Pageable(g => g.PageSize(6)
                                       .Position(GridPagerPosition.Both)
                                       .Style(GridPagerStyles.Numeric))
                         .Sortable(sorting => sorting.SortMode(GridSortMode.MultipleColumn));

And the exception likes:

Invalid property or field - 'ItemID' for type: Object

Can anyone help me to explain what's wrong?
Thanks a lot.
