Bug report
When the data source of the grid is set to WebAPI, the Batch option is not available.
Reproduction of the problem
1. Set the DataSource to WebAPI()
2. Attempt to enable the Batch(true) option.
Description
Reproducible only with the latest version of the suite - 2019.3.1023. The Batch option is available in the 2019.3.917 version.
Environment
* **Kendo UI version:** 2019.3.1023
* **jQuery version:** 1.12.4
* **Browser:** [all]
Hello,
When I try to create a Telerik UI project for .NET Core 3.0 using menu and grid options the project gets created and runs correctly, however when I try to add a new view or controller there appears to be an issue with the scaffolding (even when creating a partial view) and the creation fails.
Note: I was able to get the project to sort of work only when I added a bunch of libraries it was complaining about (see attached), however the views do not update when I make changes except only when rebuilding which does not seem correct.
There is an issue when you copy /paste a bullet list from a Microsoft word document.
- The numbers are not correct (See attached screenshot)
- If you started a new line you don't get a new number for that hierarchical level. Instead, you just get a new line.
When a model property is decorated with data annotation attributes, the RadioButton HtmlHelper does not properly render the data-val and data-val-required attributes on the element.
Expected behavior: Data attributes should be successfully rendered on the <input> element.
Bug report
The server filtering is not working for MultiColumnComboBox defined using a tag helper.
Reason: The initialization script returns:
..... kendo.ui.ComboBox.requestData(.....
instead of
..... kendo.ui.MultiColumnComboBox.requestData(.....
Reproduction of the problem
For reproduction details please refer to ticket: #1435798
Current behavior
The server filtering is not working and the server returns all items from the DataSource.
Expected/desired behavior
The server should filter the response based on the data coming from the view.

Hello,
We are subscribing to the change event of scheduler on clicking any event/Slot , the functionality works fine with window machines.
In iPad the change event gets triggered on clicking any part of scheduler. for instance when i click the show Full day text below it triggers the change event in iPad but not in windows.
Please let us know how to restrict change event to be triggered only when a slot/event is selected in iPad.
Thanks.
We are upgraded from MVC 5 to MVC-Core and using now your core components (latest version).
In our AutoComplete box, we get now a NullReference exception, without changing anything at our codebase.
Generated Script from Kendo MVC-Core:
kendo.syncReady(function(){jQuery("#txtSearchForLink").kendoAutoComplete({"select":insertLink.searchResultSelected,"dataTextField":"Text","filter":"Contains","footerTemplate":jQuery('#searchResultFooterTemplate').html(),"minLength":0,"placeholder":"Suchen","template":jQuery('#searchResultTemplate').html(),"dataSource":{"type":"aspnetmvc-ajax","transport":{"read":{"url":"/Orphy/Search/GetQuickSearchData","data":insertLink.onAdditionalData}},"serverFiltering":true,"serverGrouping":true,"sort":[{"field":"Weight","dir":"desc"}],"group":[{"field":"GroupName","dir":"desc"}],"filter":[],"schema":{"data":"Data","model":{"id":"Id"}}}});});
Debugging:
-> context.Count == 0 -> so Null will returned
-> Here you access the property Memeber of Null ... ?
Call Stack:
System.NullReferenceException: Object reference not set to an instance of an object.

Bug report
The data attributes are not rendered for the DropDownlist when bound to Model in Razor Pages.
Reproduction of the problem
View:
@page
@model TelerikAspNetCoreApp12.Pages.IndexModel
<form>
@(Html.Kendo().DropDownList()
.Name("fabric")
.OptionLabel("Select...")
.DataTextField("Text")
.DataValueField("Value")
.BindTo(Model.Data)
.Filter("contains")
)
<input type="submit" />
</form>
Back end:
namespace TelerikAspNetCoreApp12.Pages
{
public class IndexModel : Microsoft.AspNetCore.Mvc.RazorPages.PageModel
{
public List<TestModel> Data { get; set; } = new List<TestModel>();
public void OnGet()
{
for (int i = 1; i <= 100; i++)
{
Data.Add(new TestModel() { Text = "product" + i, Value = i.ToString() });
}
}
}
}
Model:
namespace TelerikAspNetCoreApp12.Models
{
public class TestModel
{
[Required(ErrorMessage = "Please select")]
public string Text { get; set; }

}
}
Inspect the input field for the DropDownList. It does not have data-val and data-val-required attributes.
Current behavior
The data attributes are not being rendered.
Expected/desired behavior
The data attributes should be rendered.

The Kendo UI Sortable for ASP.NET Core assumes that all selectors are by "id".
Reproduction of the problem
1. Set the .For() option of the Sortable widget to a class selector:
@(Html.Kendo().Sortable()
.For(".k-grid table")
// . . .
)2. Inspect the page source.
3. The following string is rendered:
<script>
kendo.syncReady(function () { jQuery("\\.k-grid table").kendoSortable(// options) });
</script>
Expected/desired behavior
The Sortable widget should allow for passing any jQuery selectors.

Hi!
We're using a drop down list as a grid cell's edit template, but.. our users are unable to properly edit the rows at the bottom of the grid due to drop down list going off the page, and closing when they attempt to scroll.
any ideas?

Bug report
In Core when the ComboBoxFor helper is used as an editor in a Grid (Shared/EditorTemplates) and its Name is set, the Grid does not render and no exception is displayed, to indicate that the Name option should not be set.
Reproduction of the problem
Reproducible in the Editing custom editor Grid demo.
- Set the ComboBox' Name in the ClientCategory.cshtml template
@(Html.Kendo().ComboBoxFor(m => m)
.Name("CategoryID")
.DataValueField("CategoryID")
.DataTextField("CategoryName")
.BindTo((System.Collections.IEnumerable)ViewData["categories"])
)
Current behavior
We throw an exception when the Name is set (e.g. if the ComboBox is used outside of a Grid), but in this scenario it is not displayed.
Expected/desired behavior
An exception is thrown and its message is displayed.

Dears,
While browsing the new components of UI for Asp Core, I found an Issue in the provided online sample (https://demos.telerik.com/aspnet-core/ripplecontainer/index)
After transferring and moving items between the lists of "RIPPLE ON LIST ITEMS", the list display the raw HTML of the items. So, I provided a screen record reproducing the issue (https://pasteboard.co/I7Fx0AW.gif).
The Menu TagHelper does not render correct links for its items when the asp-page attribute is used.
With area it does not render a link at all:
<menu-item text="Home" asp-area="Products" asp-controller="Home" asp-action="About"></menu-item>
Without area it renders an incorrect link
<menu-item text="Login" asp-area="Products" asp-page="/Books"></menu-item>
Hello good afternoon all right?
I am developing a code where I create a base model of a window and use javascript to be able to define data like autura, width, content (URL) and etc ...
In the example I am doing, I have a menu that according to the ID of the item that I clicked on the menu, it performs a function and according to the ID, it defines the data of the Window, as I do not have a component like "RadWindowManager" to facilitate this part of the creation, I am doing this process:
Component Code:
<nav class="navbar navbar-expand-xl navbar-light bg-light">
<a class="navbar-brand" href="#">
<div> <img src="~/images/selo.png" class="pull-left imagem" /> </div>
</a>
<a class="navbar-brand" href="#">
<img src="~/images/softlux.png" class="logo_posicao" alt="">
</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarText" aria-controls="navbarText" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarText">
<ul class="navbar-nav mr-auto">
<li class="dropdown nav-text">
<a href="#" class="nav-link dropdown-toggle" id="navbarDropdownMenu" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" onclick="aoClicar('3,0')">
Example Window 1
</a>
</li>
<li class="dropdown nav-text">
<a href="#" class="nav-link dropdown-toggle" id="navbarDropdownMenu" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" onclick="aoClicar('6,0')">
Example Window 2
</a>
</li>
<li class="dropdown nav-text">
<a href="#" class="nav-link dropdown-toggle" id="navbarDropdownMenu" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" onclick="aoClicar('12,0')">
Example Window 3
</a>
</li>
</ul>
</div>
</nav>
@(Html.Kendo().Window()
.Name("FrmGrid")
.Resizable()
.Draggable()
.Content("Loading...")
.Visible(false)
.Modal(false)
)Scripts Code:
<script type="text/javascript">
function aoClicar(idItem) {
switch (idItem) {
case "3,0":
var janela = $("#FrmGrid").kendoWindow().data("kendoWindow");
janela.setOptions({
title: "Table of Environments",
width: 980,
height: 440
});
janela.refresh({
url: 'http://' + window.location.hostname + ':' + window.location.port + '/Ambiente/Index' // Open a Controller and Action as Frame
});
janela.center().open();
break;
case "6,0":
var janela = $("#FrmGrid").kendoWindow().data("kendoWindow");
janela.setOptions({
title: "Table of Professions",
width: 980,
height: 400
});
janela.refresh({
url: 'http://' + window.location.hostname + ':' + window.location.port + '/Profissao/Index' // Open a Controller and Action as Frame
});
janela.center().open();
break;
case "12,0":
var janela = $("#FrmGrid").kendoWindow().data("kendoWindow");
janela.setOptions({
title: "Table of reasons",
width: 980,
height: 560
});
janela.refresh({
url: 'http://' + window.location.hostname + ':' + window.location.port + '/Motivo/Index' // Open a Controller and Action as Frame
});
janela.center().open();
break;
default:
alertify.error('Window not disponible.');
}
}
</script>
However, I noticed 2 problems in Defining Options such as height, width, title, and content
If I use this method to define:
janela.setOptions({
title: "Table of reasons",
width: 980,
height: 560
});The final result of the window looks like this:
Note that the Content Frame is passing outside the window border, or in case the background shadow of it, in other browsers the size may even follow the pattern of the shadow, but in Google Chrome you get this part beyond the limit.
If I use this method to set the properties:
var janela = $("#FrmGrid").kendoWindow({
title: "Table of reasons",
width: 980,
height: 560
}).data("kendoWindow");When you create the first window, you create it without problems:
However, if I close and try to open another menu item, properties such as Height, Width, and Title are not updated, see:
As much as I have defined the patterns before opening the window, the only thing that was changed in the window was the URL / Content
I hope you have understood what you want to report, do not forget the texts in the grid or the buttons are not in English, this project I am developing in my native language (In the case of Brazilian Portuguese)
Anyway thank you for your attention and I await your response.
Have a nice day
Hi Kendo Team,
I am working on Kendo UI ASP.NET Core Grid binding with SignalR. But while starting Hub and providing the Promise, I am facing an error "The "promise" option must be a Promise."
I am following this URL for reference: https://demos.telerik.com/aspnet-core/grid/signalr .
Checked on your website as well, but the issue is also coming there. Here is the URL: https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/configuration/transport.signalr
In this link, when clicking on "Open In Dojo" button, it opens a new window, then clicks on the Run button. It will generate an error in the console "Uncaught Error: The "promise" option must be a Promise.".
Please check the attached snapshot.
Please reply asap. Thanks in advance!
