I'm using a Grid to ajax edit a simple model in the inline mode and on the Controller the ModelState.IsValid is always false.
The error message is "The value '/Date(-62135578800000)/' is not valid for Expiration."

I have attach the relevant code of my test application and would appreciate any help.

Thanks,

Filtering Nullable Guid Column in Grid Causes Exception

I have a nullable Guid column in my grid that is using an editor template to display a the text value associated with the Guid in the lookup table.

columns.ForeignKey(p => p.NotAcceptableReason, (System.Collections.IEnumerable)ViewBag.NotAcceptableReasons, "NotAcceptableReasonId", "NotAcceptableReasonName").Width(200);

The editor template:

@using Kendo.Mvc.UI

@model object

@(

Html.Kendo().DropDownListFor(m => m)

.BindTo((SelectList)ViewData[ViewData.TemplateInfo.GetFullHtmlFieldName("") + "_Data"])

.OptionLabel("--- Select ---")

.ValuePrimitive(true)

)

On that column's column filter popup,I get all the text values from the lookup table in a drop down list and the filtering work as expected.

However, when I try to filter the column on "Is null" or "Is not null" I get an error -> System.FormatException: Unrecognized Guid format.

I suspect this is because there is no NULL entry in the lookup table I'm binding the drop down list to. Any suggestions for getting the "Is null" or "Is not null" column filters to work correctly in this scenario?

AutoComplete with MVC6 and VS 2015

Hello,

I am trying to use the AutoComplete editor with MVC6. Kendo Version 2016.3.914

I keep getting, Uncaught TypeError: jQuery(...).kendoAutoComplete is not a function when I run the page.

I found this post from last year: http://www.telerik.com/forums/missing-textboxfor-and-autocomplete#a-GwYBg2-ECJCMqxHipYVQ

Has support for AutoComplete been added yet?

Thank you!

Kendo Datepicker initial value not displaying on edge browser

We are usingc trial version of Telerik UI for ASP.NET MVC R3 2016 With MVC 4

PROJECT DESCRIPTION
We are using System.Web.Mvc version as 5.2.2.0.And Kendo.MVC.dll of version 2012.3.1114.340.
We are using kendo datepicker but on edge the saved date value is not displaying.If we put type="text" it removes the validations from that field like required filed etc. And also tried to replaced Kendo.MVC.dll of new trial version i.e. 2016.3.914.440 but still it's not working, Do we need to replace an css or js files also,If yes please let me know which are those.
We need to have common fix because we need to do this change at one common place as at many places we are using that.
Please give us the solution.

Thanks,

No Files Returned to Controller

We are currently working with the Upload control in what would seem to be a very simple setup.

@(Html.Kendo().Upload()

.Name("files")

.ShowFileList(false)

.Multiple(false)

.Async(a => a

.Save("Save", "Patient")

.AutoUpload(true)

.SaveField("files")

)

.Validation(validation => validation.AllowedExtensions(new string[] { ".gif", ".jpg", ".png" }))

)

and our controller is defined as such

[HttpPost]

public async Task<IActionResult> Save(IEnumberable<HttpPostedFileBase> files)

What is happening is that the files parameter is not null but has a count of 0. This is in an ASP.NET core MVC app.

What could the issue be? Is there something simple we are missing here?

Thanks
AJ
