Bug report

When a CheckBox is set to enabled: false, the input is missing the k-disabled class. Thus, the checkbox does not have disabled styles applied.

Reproduction of the problem

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

The desired rendering of the component - https://github.com/telerik/kendo-themes/blob/e1dbf1a74980bd82718f40085f6a8e21922f1897/tests/checkbox/checkbox-states.html#L44

Current behavior

The first checkbox is enabled and the second is disabled, but they appear the same.

Expected/desired behavior

The input should have the k-disabled class when the checkbox is disabled

Workaround

 <style>
        .k-checkbox:disabled{
          opacity: 0.6
        }
      </style>

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 kendo.version property should correctly reflect the actual build version (2025.3.1002 in this case).

The PACKAGE_METADATA placeholder should be replaced during the build or distribution process, even in the raw-js folder outputs.

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.

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.
For me, it feels more natural to invalidate the control when an invalid date is entered. This allows me to block the form from being submitted. Setting it to "min" or "max" can bypass end-user oversight, potentially resulting in incorrect date submission.

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!

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

  1. 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.

  1. Open the Dojo link I provided and Run it.
  2. Open your browser DevTools console so you can see console.log messages.
  3. Navigate to a leaf node of the tree if it isn't already open by default; ex: Daryl -> Guy -> Buffy -> Hyacinth
  4. Click in and out of an editable cell; ex: Ext
  5. Observe the DevTools console where you will see that the 'rendered XXX' text has been written for EVERY CELL in the entire tree.
  6. Expand/collapse the closest parent group
  7. 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.

  1. Open the Dojo link and Run it.
  2. Clear the DevTools console so you can see a clean display of results for the next action.
  3. Expand and collapse a child group of Daryl Sweeney.
  4. 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.

The Gantt desperately needs a way to position the title somewhere other than inside bar. Other Gantt charts I have used will allow you to place the title to the right of the bar so the title is still displayed in its entirety regardless of the pixel size of the rendered task bar.

Other kendo charts already allow similar configuration options. I have tried using the taskTemplate and css which I can get to show on the screen just below the bar however the title is then not visible in the pdf view.

, taskTemplate: function (task) {
    // move label just below and to the far right of the task bar
    return '<span class="task-label" style="position:absolute; right:0; color:#000;">' + task.title + '</span>';
}

Please advise.

Enhancement

Currently the dialog action buttons can not hold only icons, the API does not provide means to have a button with only an icon or an icon and text. Considering the aforementioned we should extend the API to allow adding of icons inside the action buttons.
