Consider the following scenario: There is a sortable Kendo-UI grid with a corresponding dataSource. Initially, the dataSource contains some items. When updating the dataSource to an empty array, all items disappear from the grid - so far, so good. However, if a column header is clicked afterwards to sort that column, the removed data reappears again.

We created a small "walkthrough" in this DOJO to demonstrate the issue.

FYI: The issue can be avoided by using a custom implementation of dataSource.transport.read which always returns the latest data.

Reproduction of the problem

Bug report

If you have several Inline Editors and a Slider, switching focus from Slider and typing in the Editors result in an error in the console.

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/EhiKaJAw/2
2. Change the Slider value
3. Go to the Editor right below the slider and type some text - it appears that the focus is stolen here as the text cursor is not shown
4. Go to the second Editor and type some text
5. Repeat steps 2-4 several times

Current behavior

An error is thrown in the console

Expected/desired behavior

No error should be thrown on the console

Environment

• Kendo UI version: 2024.1.319
• Browser: [all]

Context: There is an item that illustrates the issue here: https://www.telerik.com/forums/kendo-datepicker-value-not-populated-after-refresh-firefox-only

In Firefox, when using the asp-for tag helper to bind a c# DateTime field to an input element, then calling kendoDatePicker() on that element, the control fails to populate on a soft-refresh (F5). Upon reloading using F5 in Firefox, the input's type is set to datetime-local, and the input 's control variation is changed to the default date picker.  Then, the Kendo UI DatePicker is initialized with a blank input which normally has a type of text. 

Example project and video of issue are attached.

This is the pertinent code (also happens in latest version of Kendo as well):

    public class IndexViewModel
    {
        public DateTime DateAsDateTime { get; set; }
    }

        public IActionResult Index()
        {
            return View(new IndexViewModel { DateAsDateTime = DateTime.Today });
        }

@model IndexViewModel

<input id="dtDate" asp-for="@Model.DateAsDateTime">

<script type="text/javascript">
    $(document).ready(function () {
        $("#dtDate").kendoDatePicker();
    });
</script>

The current chat widget renders the user-input as an INPUT control, which means it cannot support multi-line support.

Wish for the option of rendering a TEXTAREA control instead of an INPUT for the chat widget:

let chat = $(target).kendoChat({
  messages: {
        placeholder: ResourceManager.GetInstance().getResource("SR_TYPE_A_MESSAGE"),
        textarea: true
    },
      user: user, 
      post: async (m: kendo.ui.ChatPostEvent) => await this.post(m),
    }).data("kendoChat");

I have a chat widget configured like this:

let chat = $(target).kendoChat({
			messages: {
        placeholder: ResourceManager.GetInstance().getResource("SR_TYPE_A_MESSAGE")
      },
      user: user, 
      post: async (m: kendo.ui.ChatPostEvent) => await this.post(m),
    }).data("kendoChat");

If the post handler tries to await a call to a web  service (to do some translation/tag substitution) then the message is posted to the chat and the results of the web call are ignored.

With version 2024.1.319, the sendMessage of chat is called twice whereas the bug doesn't exist in version 2022.3.913.

Is there a solution?

Hello,

I have an issue when I use the drag and drop of a picture in the kendo Editor inline.

Let me explain it :

1) Go to : https://runner.telerik.io/fullscreen/uWosAbib (It's the standard example on your site) on chrome 123

2) Select the last editor "Rich UI Widgets for..."

3) Take a file of a picture on your computer and drop it on the first editor "Comprehensive HTML5/..."

Two things :

* The file open on a new tab browser instead of to be added to the html of the first editor

* There is a message in the debug tools (The stack trace is added in the Attach Files)

Uncaught TypeError: Cannot read properties of null (reading 'nodeType')
    at init.index (kendo.all.js:135127:1)

Another element, if you don't select and just drag and drop it's work.

Thank you for your awesome framework and good luck with the correction !
