The Kendo Chart widget's documentation describes the setting messages.noData. However, it is missing in the typescript typings.

The documentation matches the source code, but the typings do not.

there is no binding for noData

e.g.

        noData?: boolean | undefined;

    interface ChartOptions {
        name?: string | undefined;
        autoBind?: boolean | undefined;
        axisDefaults?: ChartAxisDefaults | undefined;
        categoryAxis?: ChartCategoryAxisItem | ChartCategoryAxisItem[] | undefined;
        chartArea?: ChartChartArea | undefined;

        legend?: ChartLegend | undefined;

After applying filter or page number, the table content gets changed but the screen reader didn't inform about the same.

Repro-Steps:

The details for this can be found in ticket #1519224

Given some XML that has child nodes and attributes, I'm binding to a grid with no problem. The child grid for each row (built using detailInit) get's the data from the parent row e.data.get("BillRows")

If those rows have attributes, the '@' signs breaks the javascript for the grid. As you can see in the ticket, every attribute needs to be renamed before I can build the child grid.

Should be a way to use attributes in XML bound to a datasource/grid for all levels of grids.

Hello,

I think i have found a potential bug

In the dojo below please run it and notice the window opens fine, then close and reopen it a couple of times.

The animation => open: false is causing the window to reopen at a smaller/zoomed out size. 

If you move the window it snaps to the correct size

https://dojo.telerik.com/oDuviZak/2

Reproduction of the problem

Open this web site:
https://demos.telerik.com/kendo-ui/spreadsheet/datasource

And follow the steps provided here:
https://www.screencast.com/t/UdEKYqIve

Current behavior

The first added cell value (or row) is removed when the user deletes an empty row.
If the ID is entered, the result is even stranger:
https://www.screencast.com/t/osmVOiY7al

Expected/desired behavior

It should behave and function like Excel. I think with local/static binding there are no issues.

Bug report

Recurring events are not rendered on the correct date when an event has to be displayed on different dates in different time zones.

Reproduction of the problem

1. In our demos or the Dojo linked here create an event with starting time of 09 AM. Set the event to repeat every Monday. In the example below the timezone of the machine and the event is UTC +2 (Sofia)

Below are two events recurring and nonrecurring created with the same starting date and time in UTC +2

1. To simulate opening in different time zones change the Timezone on the machine with a difference of more than -9 hours, so the event to be expected to display on the previous day. For example, select UTS -10 Hawaii.

Current behavior

After changing the time zone on the machine from UTC +2 to UTC -10 the event is rendered at 8 PM, but it is still displayed on Monday. Thus, recurring and non-recurring events created with the same start date and time are displayed on different days when the time zone is changed:

Expected/desired behavior

The date of the recurring event should be changed according to the time zone. It should be possible to repeat events on a different days of the week when the Scheduler is opened at different timezone

In Firefox on 4K screens, the Spreadsheet vertical and horizontal scrollbars cannot be revealed or dragged with the mouse. Scrolling works only with the mouse wheel. The issue is not reproducible in Chrome or on 2K screens. The same behavior is observed in the Kendo UI for jQuery, KendoReact and Kendo UI for Angular Spreadsheet.

Steps to reproduce

1. Open the Spreadsheet overview demo in Firefox on a 4K screen (Windows with overlay scrollbars).
2. Move the mouse to the right or bottom edge of the Spreadsheet and try to reveal or drag the scrollbar.

Actual behavior

The scrollbar is not shown, or it is very hard to reveal (it appears only occasionally in the top right corner), and it cannot be used.

Expected behavior

The scrollbar is revealed on hover and can be dragged.

Cause

Firefox uses overlay scrollbars, which hide automatically, and the scrollbar width is measured as 0. The Spreadsheet's internal fixed container then covers the whole scrollable area, including the scrollbar, so the mouse never reaches it. The mouse wheel keeps working because it is handled separately.

Environment

Windows 11, Firefox, 4K display, Kendo UI for jQuery 2026.3

### Bug report

When the title of the legend in the Kendo UI Chart widget is longer, the labels are not centered as per the default legend alignment.

### Reproduction of the problem

1) Create a Chart widget and set the title of the legend to "If the title is longer than the series names is not centered anymore is left aligned";

2) The title is centered, but the labels are aligned to the left.

A Dojo sample for reproduction: https://dojo.telerik.com/UBoTOBID

### Expected/desired behavior

The labels of the legend should be centered below the title.

### Environment

* **Kendo UI version: 2021.2.616
* **jQuery version: 1.12.4
* **Browser: [all]

The issue can be observed in the following dojo example:

https://dojo.telerik.com/OWAyaZuJ

Reproduction of the problem:

1. Open the Dojo.

2. Shrink the window until only a single event is visible. Note: The open() method is called on the last item of the Timeline in the dataBound event.

3. Run the example. The last item of the timeline has been opened, however the "back" button is not active.

Current Behavior:

The "back" button is not active when it should be.

Expected Behavior: 

The button should be active, no matter the screen size.

Environment:

Kendo UI Version: [2021.2.616]

Browser: [all]

Bug report

When the value of the widget is set in the dataBound event handler the filtering events is fired and e.filter is undefined

Reproduction of the problem

1. Open the Dojo
2. Open the browser console and type something in the MultiSelect to filter the data.

Current behavior

The filtering event is fired a second time and the second time the e.filter is undefined.

Expected/desired behavior

Double-checlk if the filtering event should be fired a second time.
The e.filter and e.sender.dataSource.filter().filters[0] should return the same value.
