We use the KendoUI for jQuery framework in the enterprise SaaS application we create. Giving our clients access to their data and being able to provide a mechanism where a client could build out some of their own functionality on our Saas platform (ie accessing the Data, webservices etc) is highly desirable.

Our front end is based on a MicroUI approach, so if the client can vibecode building a new microUI, the UI experience with the other microUI we provide would be seamless. Examples might be: Create a Scheduler view showing all the European Holidays in 2026, or create a grid view populated with all the customers who have not transacted in 2025 and show their linkedin link/profile.

We can easily wrap any vide coded application into our application now using the microUI approach, but what we dont get is the same look and feel, themes and components being used. It is this we are looking to solve.

I have noticed that, after switching themes, the tooltips in our application do no longer work correctly. I was able to reproduce the issue in the following two DOJOs:

• Correct behavior: https://dojo.telerik.com/eFOcahIS (stylesheet https://kendo.cdn.telerik.com/2022.2.510/styles/kendo.default.min.css)
• Invalid behavior: https://dojo.telerik.com/ahOkibow (stylesheet https://kendo.cdn.telerik.com/2022.2.510/styles/kendo.default-ocean-blue.min.css)

The only difference between those two is the stylesheet to be loaded (line 6).

Steps to reproduce:

1. load the DOJO
2. hover over the red dot (notice how the text uses all space available and does not get wrapped unless necessary)
3. hover over the green dot 
4. hover over the red dot again

In step 4, the correct behavior would be displaying the tooltip in the same fashion as in step 2. However, in the faulty DOJO, it can be seen that the tooltip does not expand past the width of the text that is displayed when hovering over the green dot. This means that when displaying long tooltips after short ones, they are always wrapped unnecessarily.

A way to fix this behavior (and what's actually the difference between the two stylesheets) is to set the position on the ".k-animation-container" back to its default value "static". Usually, this value is overridden by the output of the size calculations, but during the calculations this value comes to play.

This third DOJO demonstrates the fix described above.

Please note that when using the default-ocean-blue stylesheet, the positioning of the callout seems to be broken as well.

Dear Team,
Currently, Telerik Smart Grid AI features rely on external AI services (e.g., OpenAI cloud). While this works well, customers who cannot use online services face challenges when trying to integrate local models (such as Ollama).

Since the Smart Grid already exposes its schema to the AI service, it would be highly beneficial if Telerik could provide at least one default AI service (hosted and managed by Telerik) that:

• Works seamlessly with dynamic/auto-generated columns

• Supports basic grid operations such as sorting, filtering, paging, highlighting, and grouping

• Ensures compatibility with the Telerik.AI.SmartComponents.Extensions package

Rationale:

• Many enterprise customers have restrictions on using cloud-based AI services and prefer local or vendor-hosted solutions.

• A default AI service from Telerik would simplify integration, reduce configuration overhead, and guarantee compatibility with Kendo Grid features.

• This would also ensure consistent behavior across environments without requiring customers to experiment with different local models.

Impact: This feature would significantly improve adoption of AI-powered grid functionality for customers with strict data policies, while ensuring a smooth developer experience.

Reference: For more details on the issue and context, kindly refer to the support ticket: Telerik Support Ticket #1707506 (https://www.telerik.com/account/support-center/view-ticket/1707506)

Environment

* **Kendo UI version:** 2025.4.1217

Bug report

After exporting/saving an image using the Kendo Drawing API, the styles added for the export remain.

Reproduction of the problem

1. Go to this Kendo UI Dojo.
2. Inspect the component

Current behavior

Transition remains at none after exporting.

Expected/desired behavior

Explain what the expected behavior of the functionality is

This behavior has occurred since version 2024.4.1112

Create a grid with batch set to true and update a field value using the set method of the kendo.data.Model object in JavaScript. The grid cell will be marked as dirty but the "Save changes" or "Cancel changes" buttons will not display. If you click into another editable cell, then the buttons will display.

See https://dojo.telerik.com/TwTMSsrB and attached example.html.zip.

See attached image.png for example image.

Bug report

When using the Selection and Export Grid Demo in Safari, and pasting the cells in Excel, there appears to be some extra empty lines below the paste.

Reproduction of the problem

1. Open the demo URL in Safari browser.
2. Select few cells and choose Copy option from the context menu.
3. Open an Excel file and paste the copied items (extra empty lines are pasted at the end).

Expected/desired behavior

The pasted lines should not include any additional empty lines beneath the specific content.

Environment

• Kendo UI version: 2022.2.802
• jQuery version: All Supported
• Browser: all

Hi Team,

I would like to request adding visual page breaks with header/footer features.  Comparatively, SyncFusion has this included and it would be great to have Telerik add these features.

Thank you!

The different Date/Time Pickers contain of an input field and a button that opens a calendar view in a popup. Usually, the background color of the button changes when it is clicked. In Firefox, nothing happens, because it seems to block the :active pseudo class. This DOJO demonstrates the behavior.

In other, similar input widgets like the NumericTextBox, this problem does not occur, because the .k-selected class is set on the button instead. Still, Firefox blocks the :active pseudo class.

Bug report

When sorting is enabled for a virtualized Grid, in some cases, after scrolling to the bottom, the Grid does not show enough items to fill the tnire table.

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/XZAkgwxd
2. Scroll to the bottom and sort the table, for example, by ID

Current behavior

The Grid shows only the last page of items, while there are enough items to fill up the entire table

Expected/desired behavior

Enough items to fill the Grid height should be displayed. There should be no blank space without records.

Environment

• Kendo UI version: 2025.4.1111
• Browser: [all]

Hi Team,

While I understand there are release notes and breaking changes, I would like to request you consider adding some version information to the documentation.  This would help identify when certain features were introduced.  

Thank you!

When a kendoContextMenu is applied to a combobox (html tag select) you are not able to show the select options by tapping it. The behaviour is on mobile browser only (tested iPad and Google Chrome developer tools with device toolbar enabled).

I reproduced the issue in telerik dojo, here is the code.

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 ]

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
