It will be really useful if we could include a new 'filtering mode' in which operators like 'and' or 'or' are allowed in the filtering input box.

For instance, using the "doesnotcontain" with 'march or july or september' will allow users to exclude multiple conditions in a single filter

Bug report

When a user edits a cell/row and presses enter, the cell is marked as dirty. However, the Save and Cancel buttons remain disabled, thus the user should focus on a different cell before being able to save changes.

Reproduction of the problem

1. Dojo - https://dojo.telerik.com/JuMumnqH
2. Edit a cell and press 'Enter'

Current behavior

The cell is closed and marked as dirty, the 'Save changes and 'Cancel changes' buttons remain disabled.

Expected/desired behavior

The buttons should be enabled once the cell is marked as dirty.

Workaround

cellClose: function(e){
                e.sender._toggleToolbarEditingItemsVisibility()
},

Environment

• Kendo UI version: 2025.2.520
• Browser: [all ]

Bug Report

When building with NPM, the glob is mismatched. This is currently related to the source code build.

Reproduction

1. Build with version 2025.2.702 in NPM.

Current behavior

Receiving the specific error message:
[!] SyntaxError: The requested module 'glob' does not provide an export named 'default'

Environment

• Kendo UI version: 2025.2.702
• jQuery version: All supported versions
• Browser: all

We would like the ability to execute custom actions once a control has been fully initialized and rendered.

Use Case
On our login page, we use the Form control. After the Form control is created, we need to reposition our SSO buttons so that they appear beneath the default buttons rendered by the form. Without a reliable event, it is difficult to determine when the control is ready for safe modification.

Proposed Solution
Introduce a Created event (or similar) that is triggered once the control is fully rendered. This event would provide a hook for developers to perform additional UI adjustments or integrate custom functionality.

Reference
Syncfusion ASP.NET Core controls provide this functionality through a Created event.

Currently, the Kendo UI RangeSlider provides a single-colored track (.k-slider-track) with a separate style applied only to the selected range. However, in many modern design requirements, there is a need to split the track into multiple colored sections (e.g., 3 or more segments with different colors) to visually represent thresholds, ranges, or categories.

Example Use Cases:

• Displaying low, medium, and high ranges with green, yellow, and red colors.

• Visualizing different risk or performance levels directly on the slider track.

• Providing a better UI experience by mapping ranges to business values.

Requested Feature:
Add native support to configure multiple color segments within the RangeSlider track (either via configuration options or styling hooks). Ideally, developers should be able to specify:

• Number of segments.

• Color for each segment.

• Segment boundaries (percentage or value-based).

Workarounds Tried:
Custom CSS overlays and pseudo-elements can partially simulate the effect, but they are not reliable or fully aligned with the slider’s rendering behavior.

Impact:
This feature would enhance usability and visualization, making the RangeSlider more flexible for dashboards, financial apps, performance monitoring, and other business-critical UI scenarios.

Reference:
Please find an attached image illustrating the requested multicolored track (example with 3 segments: green, yellow, and red).

On Kendo's grid Custom Command, there's a bug with "text" object of "command". The bug is we can't use space in the "text" object, not even %20.
This is because the "text" object is appended on class attribute of the command button.

Find Node or search mode

We are using Metro theme, and many clients say us that is a little bit difficult to distinguish parent from child items in a panelbar because they are too similar. Is possible to introduce an left padding to recreate a fake tree?

Add client-side filter method that automatically updates the filter menu options (dropdowns and values) according to the filters described in the filter expression.

How about a simple addition to zooming, whereby the zoom just automatically zooms into the current data set by filtering off the outer elements? For example, have a zoomStep property, which defines the number of elements to filter off the start and end of the data. This would allow really simple zooming without having to write filters and would allow for easy use in shared code scenarios (eg, we have a single Knockout custom binding for all our charts).

We have defined a work start and end time for the scheduler. However if the user shows full day in the scheduler we want to make sure the scheduler is scrolled to the start time (when the scheduler is either init or when the user clicks on the show all day button). So basically if there is an API exposed to make the scheduler scroll to a given time then this will work. Please also refer to ticket#: 845019

See http://hammerjs.github.io/

The toolbar has buttons and split buttons but no menu button.

A menu button is a button which triggers a popup button; in other words it is a splitbutton without the split. See http://getbootstrap.com/components/#btn-dropdowns-single

Easy to do and really useful!

Per the post here:  http://www.telerik.com/forums/does-the-kendo-ui-grid-support-column-header-templates

In order to achieve a custom header, we have to manipulate the DOM via jquery.  That can get messes and makes the grid less maintainable.

Sitefinity uses KendoAll everywhere, here's an example of how it's used CMS-wide
https://github.com/Sitefinity/feather/blob/a9a417115096af67629603cf0eaf52e8a6810d06/Telerik.Sitefinity.Frontend/Mvc/Views/Designer/Designer.cshtml#L53

The basic idea is that when the page is built at runtime all the references to the script get combined and it's only served once.  So the stock widgets just all reference KendoAll and if there's 100 widgets on a page that the user creates, KendoAll only comes down once...

So in the SF backend we can set what "ScriptRef.KendoAll" means... like which script it points to, or even to use the CDN version.

Typically what I do to cut the size is to change the KendoAll script to KendoWeb CDN because nothing in Sitefinity uses KendoMobile so why constantly deliver the massive bundle.

However there's been a bunch of times where KendoDataViz has been required on the sites, and now I'm stuck... because you can't just add KendoWeb and KendoDataviz seperatly on a page due to the overlap of functionality.

Option 1: Change the entire site back to KendoAll
Option 2: Generate a custom build and use that

Problem with option 1 is I'm back to delivering a couple meg file to users

Problem with option 2 is I can no longer use a CDN, and every release I'm having to keep re-generating a new bundle file.

It would be very very very nice if a pre-generated DataViz+Web (and seperate DataViz+Mobile) build was available on the CDN to use.

As mentioned here: http://www.telerik.com/forums/please-make-apis-used-in-your-sample-projects-official-public
you make use of kendo.date and kendo.timezone in your examples. It would be nice to know a bit more about those. And to have them available in typescript.
