The issue is a regression starting with 2025.4.1111 version.
Environment
- Kendo UI version: 2025.4.1111
- Browser: [all ]
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 preview above the Kendo UI ArcGauge to show the potential colors similar to the appearance of the RadialGauge.
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.

- Open the DateTimePicker to check the selected date
- 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'
Expected/desired behavior
The PACKAGE_METADATA placeholder should be replaced during the build or distribution process, even in the raw-js folder outputs.
Environment

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.
Note: In some situations, the default behavior of setting it to "min" or "max" can also be useful... but with a change event trigger however!
Hi Team,
I would like to request a built in way to add Multi-Filtering for the TreeList/Gantt. Additionally, it would be nice to have an easier way to access the TreeList and its associated FilterMenu events.
Thank you!

Bug report
In the Scheduler, if we have a slotTemplate and at the same time views.virtual, the resources().field in the slotTemplate always returns the same value (of the first resource).
Reproduction of the problem
- Open the Dojo - https://dojo.telerik.com/lJnddiLz
Current behavior
The data-resource='#= resources().user_id #' in the slotTemplate always has the same value.
If the virtual is disabled, the data-resource='#= resources().user_id #' has a value based on the resource.
Expected/desired behavior
The resources should be correctly returned in the slotTemplate even if the virtual option is enabled.

Bug Report
When using the DatePicker with the Chinese Traditional Microsoft Zhuyin input method, pressing a number key results in the number being entered twice into the input field. This does not occur with standard input methods (e.g., English US). The issue appears to be related to how the input method editor (IME) interacts with the DatePicker's input handling.
Steps To Reproduce
Open the Dojo:
Go to https://runner.telerik.io/fullscreen/YXQqjzdx
Locate the DatePicker:
Click on the input field that opens the Kendo UI DatePicker.
Switch Input Method:
Change your keyboard input method to:
Chinese Traditional - Microsoft Zhuyin Input Method (體中文微軟注音輸入法)
Type a Number:
Press any number key (e.g., 1, 2, etc.) on your keyboard.
Observe the Behavior:
The number appears twice in the input field (e.g., pressing 1 results in 11).
Actual Behavior
Number being entered twice
Expected Behavior
The number shall be entered once
We have noticed a serious performance issue in the TreeList control which I have confirmed in the latest version in this Dojo: https://dojo.telerik.com/aNuKanAG. This Dojo is a based on the TreeList in-cell editing demo from your website.
- Open the Dojo link I provided and Run it.
- Open your browser DevTools console so you can see console.log messages.
- Navigate to a leaf node of the tree if it isn't already open by default; ex: Daryl -> Guy -> Buffy -> Hyacinth
- Click in and out of an editable cell; ex: Ext
- Observe the DevTools console where you will see that the 'rendered XXX' text has been written for EVERY CELL in the entire tree.
- Expand/collapse the closest parent group
- Again, observe that EVERY CELL has been re-rendered
I was trying to figure out if there was any good reason for this. In the Dojo above all data are nested under a single parent. So, I created another Dojo but this time there are two separate parent groups: https://dojo.telerik.com/OcEmAgIz. This Dojo is based on the Binding to local data demo from your website.
- Open the Dojo link and Run it.
- Clear the DevTools console so you can see a clean display of results for the next action.
- Expand and collapse a child group of Daryl Sweeney.
- Observe the console log results: you will see that Dan Sweeney was also re-rendered.
The problem here is that these re-renders are very expensive. Imagine if the call to console.log was instead something else that might need a bit of computation time to complete.
The simple act of expanding and collapsing a group from an unrelated part of the tree, or simply opening and closing an editable cell should not result in the entire tree being re-rendered. This is a serious performance issue, and seems completely unnecessary.
What I have demonstrated in the Dojos I created is that Kendo is re-rendering the ENTIRE structure. The goal of this feature would be to rerender only the specific cells of the treelist that have been impacted by an edit.
