Bug report

NORM.S.INV, NORM.INV, and NORM.DIST are officially listed as supported formulas, but they are not functioning properly

Regression bug since 2024.4.1112

Reproduction of the problem

Open the Demos - https://demos.telerik.com/kendo-ui/spreadsheet/index

Paste: =NORM.S.INV(0.908789)

Result must be 1.3333347

Environment
Kendo UI version: 2024.4.1112
Browser: [all ]

Bug report

Reordering in the same column is not working correctly

Reproduction of the problem

1. Open the Demos - https://demos.telerik.com/kendo-ui/taskboard/remote-data-binding
2. In the first column, move "Campaigns" below "Customer Research."
3. Check the Network tab of your browser, and no update is sent. The "Campaigns" is moved back to the top. Sometimes an update is sent but it contains the wrong index, so the item is still on top.

Current behavior

The task order remains the same

Expected/desired behavior

IT should be possible to reorder the tasks in the same column

The issue is a regression starting with 2025.2.520 version

The TileLayout is a great way to show data in a dashboard, but lacks a dataSource to allow dynamic generation of them. I have had to create a custom extension that introduces a dataSource, which then utilises `widget.setOptions({ containers: items })`. But this puts too much reliance on custom code and is a worry that it will break between version upgrades. Also, editing one container doesn't allow the refreshing of one tile; I need to reset the whole lot using `setOptions`.

Adding, editing, resizing, and re-ordering are also difficult to implement for a tool that has huge potential.

Hi Telerik Team,

I’m using Kendo UI version 2022.3.1109 with jQuery, and I have implemented a Kendo UI ImageEditor in my application. I would like to restrict the allowed file types when users open an image from their device.

Goal
I want the ImageEditor to accept only a specific set of formats:

• .png
• .jpg/jpeg
• .webp

Current Behaviour

When the user clicks the Open tool inside the Image Editor:

• It allows all file types, including unsupported ones
• There is no configuration option like the accept attribute available in Kendo Upload
  
  I checked the documentation but could not find any built-in way to filter file types for the ImageEditor Open dialog.

Regards,
Amit

Hi Team,

I would like to request a chart which visually displays workflow data similar to a Gantt chart but in pivoted form.  

Thank you!

Bug report

When there are multiple Property Grids on the page, all the Property Grids have the column width as configured for the first one.

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/qxeixekp

Current behavior

The second and third PropertyGrids have the same width as the first PropertyGrid, although their configuration is different.

Expected/desired behavior

Each instance should have column widths based on the configuration.

Bug report

When the sortable option is disabled, the title in the header is not wrapped in span element with 'k-column-title' class.

Reproduction of the problem

1. Open the Dojo and inspect the titles - https://dojo.telerik.com/hKCCsAOU

Current behavior

Rendering with sortable enabled:

The filtering icon and title have enough space:

Rendering with sortable disabled:

filtering icon overlaps the title in case of long text:

Expected/desired behavior

The rendering should be identical. The header title should be wrapped in a span element with 'k-column-title' class

Workaround for fixing the overlapping issue:

<style>
    .k-grid-header .k-filterable{
      padding-right: calc(1.42857143em + 14px);
    }

Currently, Kendo UI for jQuery components rely on innerHTML and direct DOM manipulation throughout their internal implementation. This occurs in multiple components.

Thus, when "require-trusted-types-for 'script';" is included, errors such as - `This document requires 'TrustedHTML' assignment. The action has been blocked.` and `TypeError: Failed to execute 'write' on 'Document': This document requires 'TrustedHTML'` - appears on the page.

I would like to request Trusted Types Support for Kendo UI for jQuery components.

Hi Team,

I would like to request a built-in way to set a gradient area between line series.  

Thank you!

Hi Team,

I would like to request a way to hide all columns with the columnMenu instead of requiring one to remain. 

Thank you!

Incorporate page breaks into the Gantt PDF Export and include option to repeat column headers on each page.

In our use case, we have linear gauges that show different colours depending on the time of day.

Our users need to be able to move the pointer up and down to view the corresponding values. 

As you can see in the below image, currently we have a workaround to show a slider above it and then move the pointer up and down accordingly, as the slider is moved. However, this does not always work perfectly, and sometimes the slider doesn't line up.

It would be nice if there were an option on the linear gauge to make the pointer moveable (false by default) and then also have corresponding events e.g. when the movement starts/stops.

Bug report

When you use the setOptions method on the DateTimePicker, the selected date is lost

Regression introduced with 2024.4.1112

2. Open the DateTimePicker to check the selected date
3. Select the AM checkbox, which will call the setOptions method, and open the DateTimePicker again

Current behavior

The selected date is lost

Expected/desired behavior

The selected date should be persisted

The DropDownList's Keyboard Navigation Docs specify that the arrow keys move the highlight in the dropDownList, while Enter selects the highlighted item.

However, in reality, the arrow keys already select items. Via keyboard, it is not possible to select e.g. the third item in the list without selecting the first and the second item first (by pressing the down arrow).

E.g. the docs for Angular describe a different behavior.

Bug report

When using the raw JavaScript files from the src\src\dist\raw-js folder (included directly via <script> tags), the Kendo UI version (kendo.version) always returns 0.0.0, and the package metadata in kendo.all.js has the version field hardcoded to 0.0.0.

Reproduction of the problem

1. Download Kendo UI for jQuery commercial distribution.
2. Use the files from the following path:
`src\src\dist\raw-js\`

3. Include kendo.all.js (and other scripts) directly in an HTML page using <script> tags.
4. Include a valid license key using:

`KendoLicensing.setScriptKey("your-license-key");`
5. Run the application and inspect the console.

Call: console.log(kendo.version);

Result: The version displayed is "0.0.0".

Current behavior

kendo.version returns "0.0.0".

_parsedPackageMetadata in kendo.all.js shows:

version: '0.0.0'

Please make the speech to text button/suffix of a kendo textarea available via mvvm. Also speech to text button to come standard as a tool in the kendo editor.

When I add a minimum or maximum value to the date picker, the control allows out-of-range dates to be entered until the dateInput option is set to true. At that point, any out-of-range date will be set to either "min" or "max." The change event will not be called for that change.

This would be perfect:

• The default behavior is to set the minimum or maximum value when the date input value is out of range. It would be nice if this behavior didn't depend on the dateInput option.T
• Trigger a change event when the control itself sets the minimum or maximum value.
• Add an option to change the behavior to generate an error on the control when an out-of-range value is entered.
