Environment

• Browser: [all]

In the latest version of Kendo UI, various input controls like the NumericTextBox or the ColorPicker now consist of an input field and a button control (used for increasing/decreasing the value or opening the dropdown).

The border-radius for those widgets can be controlled by setting the "rounded" option. At the same time, when using SASS themes, a button's default border-radius might be set using the $kendo-button-border-radius variable. The buttons inside e.g. a NumericTextBox do not override the theme's border-radius which leads to an outcome like this:

Widgets that use Buttons internally (and therefore offer no way of overriding the button's border-radius by setting its "rounded" option manually) should override the default styles.

Unfortunately, I could not reproduce the behavior in a DOJO, because I cannot transpile SASS themes there.

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>

Bug report

The DropDownTree allows us to configure its checkChildren and filter options. Both options are working correctly, when used separately.

When the two options are defined for the DropDownTree, the checkChildren options don't select the child elements of a given node that is checked.

Reproduction of the problem

1. Open this Dojo example
2. Expand the DropDownTree popup
3. Check the "Furniture" node checkbox

Current behavior

Only the "Furniture" checkbox is being checked

Expected/desired behavior

The "Furniture" and all of its child nodes should be selected when clicking on the "Furniture" checkbox.
Here is a Dojo example in which the checkChildren configuration is working as expected.

Hi,

When I double click a cell and enter into editing mode, scrolling up or down will make the editor div out-of-place. 

It should follow the target cell instead.

This can be easily reproduced here: https://demos.telerik.com/kendo-ui/spreadsheet/index

It seems Kendo UI for Angular/React also have the same issue.

kendo.all.min.js is reporting this in Chrome.

A page or script is accessing at least one of navigator.userAgent, navigator.appVersion, and navigator.platform. In a future version of Chrome, the amount of information available in the User Agent string will be reduced.

To fix this issue, replace the usage of navigator.userAgent, navigator.appVersion, and navigator.platform with feature detection, progressive enhancement, or migrate to navigator.userAgentData.

Note that for performance reasons, only the first access to one of the properties is shown.

https://blog.chromium.org/2021/05/update-on-user-agent-string-reduction.html

When will this be resolved?

Reproduction of the problem

1. Follow the steps described in the link here - https://github.com/telerik/kendo-ui-core?tab=readme-ov-file#building-kendo-ui-core
2. Create a custom script for validator npx gulp custom -c validator
3. Try to load the script and create the components

Current behavior

The validator is not working, error is shown

jQuery.Deferred exception: $(...).kendoNumericTextBox is not a function

Expected/desired behavior

The components should work as expected when custom script is created

The "Classic" SASS theme for Kendo UI (v. 5.4.0) provides the $enable-transitions variable. I expected it to behave consistent with other similar variables like $enable-rounded which means that when it is set to false, no transistion properties would be set.

However, the following elements always have a transition property set, no matter what the value of $enable-transitions is:

• .k-button::before
• .k-list-item

Is this a bug or did I understand the meaning of $enable-transitions wrong?

Environment (OS, Application, Versions): 

OS Version: 22H2 (OS Build 25352.1)
Edge Dev: Version 121.0.2277.112 (Official build) (64-bit)

Third Party Name:   Kendo

Repro Steps: 

   1. Open https://codepen.io/oneID/pen/LYaGREP and turn on NVDA.
   2. Navigate to 'Populate' grid and activate it using enter key.
   3. Navigate to Expand button present under domain in Export to excel table.
   4. Observe if the screen reader is announcing correct role and name for the expand button or not.

Actual Results: 

Accessible name for the 'expand' button is not correct, Expand button is defined as link.

Expected Results:

Accessible name of 'expand' button should be sufficient for screen reader user. Accessible name should contain value available in domain as well.

Role should be defined as 'Button' as its behaving as button.

Hello Team,

We are currently facing challenges with the Kendo grid, which is a widely used widget or component at o9Solutions. Although we have been using Kendo for a long time, the widget is failing to meet accessibility standards for some components, which are crucial in today's world.

Regarding the Kendo grid, there is an issue where SR is reading the table twice, once for the header and once for the cells. This can cause confusion for assistive technologies like SR.

Consider the cases of horizontal scroll or fixed column cases also.

Having a single <table> is the standard. We can't create multiple tables, which will violate the good coding practices + accessibility standards.

---

I saw some posts regarding this... where it was mentioned we can remove this Scrollable() . But what are the cons of this if we remove this?
--

We want this functionality like a horizontal or vertical scroll or fixed column cases.But it needs to recognize as a single table.
