Hello Team;

Do we have a Kanban Widget in Kendo UI for ASP.Net Core 2.1?
I saw an application that had used Kendo UI jQuery widget and they told me their Kenban widget was from Telerik. However, when I look at t he list of ASP.Net core widgets I can't find any with that name.

Could you please shed some light where to find it?
Thanks!

when i update window with 

$(window).resize(function(){

});

my is fall and need reload window

     Hello,

I am trying to put an upload in a grid's editor so i can add a profile picture to my users. However, when the save action is called i always receive a null object. I am using an EditorTemplate to put the upload control in the grid's edit mode. 

I suspect that the reason it does not work has something to do with the Editortemplate since if i copy my upload control in my main view, it sends the files to the controller properly.

here are the relevant code snippets:

Controller  
[HttpPost]
        public ActionResult Save(IFormFile files)
        {
            //Do save
            return Content("");
        }

Editortemplate

@model string

@(Html.Kendo().Upload()
        .Name("files")
        .Multiple(false)
        .Async(a => a
            .Save("Save", "File")
            .AutoUpload(true)
        )
)

The grid Column 

            columns.Bound(c => c.ProfilePicture).Title("Photo").EditorTemplateName("FileUpload").ClientTemplate("<img src='" + Url.Action("GetImage", "File") + "?imageID=#= ProfilePicture.ID #' alt='Profil' height='172' width='147'>").Width(160);

Hi, I think this is a bug.  

This menu item will not work:

This menu item will work:

The only difference is the underscore.  The underscore can be anywhere in the action name, but if it's not there, Telerik won't build the link with the action.  

Are my actions required to have underscores? 

When using DateInputFor on a required nullable datetime it allows submit when date is blank. It should throw a field required error like DatePicketFor. Same error if you use DatePickerFor(...).DateInput().
