[Solved] Bug - Adding filter to nullable datetimediseable popup filter box

[Dadv]

Hi,

I try to add a filter for a nullable datetime an found a strange behavior.

I had add the filter .Filters(f=>f.Add(a=>a.OrderDate).IsNotEqualTo(null))) to the  'Grid First Look' of the example  project :  

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<IEnumerable<OrderDto>>" %>

 

<asp:content contentplaceholderid="maincontent" runat="server">

<% using (Html.Configurator("The grid should...")

              .PostTo("FirstLook", "Grid")

              .Begin())

   { %>

    <ul>

        <li><%= Html.CheckBox("ajax", true, "make <strong>AJAX</strong> requests")%></li>

        <li><%= Html.CheckBox("grouping", true, "allow <strong>grouping</strong> of data")%></li>

        <li><%= Html.CheckBox("filtering", true, "allow <strong>filtering</strong> of data")%></li>

        <li><%= Html.CheckBox("paging", true, "have <strong>pages</strong> with 10 items")%></li>

        <li><%= Html.CheckBox("scrolling", true, "show a <strong>scrollbar</strong> when there are many items")%></li>

        <li><%= Html.CheckBox("sorting", true, "allow <strong>sorting</strong> of data")%></li>

        <li><%= Html.CheckBox("showFooter", true, "show footer")%></li>

    </ul>

    <button class="t-button" type="submit">Apply</button>

<% } %>

 

<%= Html.Telerik().Grid(Model)

        .Name("Grid")

        .Columns(columns =>

        {

            columns.Bound(o => o.OrderID).Width(100);

            columns.Bound(o => o.ContactName).Width(200);

            columns.Bound(o => o.ShipAddress);

            columns.Bound(o => o.OrderDate).Format("{0:MM/dd/yyyy}").Width(120);

        })

        .DataBinding(dataBinding =>

        {

            dataBinding.Server().Select("FirstLook", "Grid", new { ajax = ViewData["ajax"] });

            dataBinding.Ajax().Select("_FirstLook", "Grid").Enabled((bool)ViewData["ajax"]);

        })

        .Scrollable(scrolling => scrolling.Enabled((bool)ViewData["scrolling"]))

        .Sortable(sorting => sorting.Enabled((bool)ViewData["sorting"]))

        .Pageable(paging => paging.Enabled((bool)ViewData["paging"]))

        .Filterable(filtering => filtering.Enabled((bool)ViewData["filtering"])
                                  .Filters(f=>f.Add(a=>a.OrderDate).IsNotEqualTo(null)))

        .Groupable(grouping => grouping.Enabled((bool)ViewData["grouping"]))

        .Footer((bool)ViewData["showFooter"])

%>

</asp:content>

the Filter work fine, the background color of the filter icon of the order date change like expected, but all the filter icon lose there 'clickability', 

I think it's because Nullable value is not accepted in the filter popup box for date (it will be great to add in the filter type list IsEqualToNull and IsNotEqualToNull and diseable the calendar textbox if this is choose).
