Hi!

I have noticed the following behavior of the Kendo-UI MultiSelect widget (reproducible in this DOJO):

1. focus the button
2. click on the X button of the selected tag in the MultiSelect to remove it

-> the button is still focused

The user has interacted with the MultiSelect, so it should grab the focus. Since the tag is removed, I would have expected the whole widget to be focused instead. At least this is what happens when clicking the "clear" button.

If a Scheduler event's start time is set differently than :00 or :30, the event will be dropped in an incorrect slot when snap is enabled. The start time in the hint is also incorrect.

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/oSaQUCOp/13

3. Drop the event

Current behavior

The event will be placed at 2:19 AM instead of at 2:00 AM

Expected/desired behavior

The event should be placed at the dropped slot.

Hello,

I have an issue when I use the drag and drop of a picture in the kendo Editor inline.

Let me explain it :

1) Go to : https://runner.telerik.io/fullscreen/uWosAbib (It's the standard example on your site) on chrome 123

2) Select the last editor "Rich UI Widgets for..."

3) Take a file of a picture on your computer and drop it on the first editor "Comprehensive HTML5/..."

Two things :

* The file open on a new tab browser instead of to be added to the html of the first editor

* There is a message in the debug tools (The stack trace is added in the Attach Files)

Uncaught TypeError: Cannot read properties of null (reading 'nodeType')
    at init.index (kendo.all.js:135127:1)

Another element, if you don't select and just drag and drop it's work.

Thank you for your awesome framework and good luck with the correction !

Bug report

When ListBox contains a long string it does not display a scroller.

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/@NeliKondova/ASuvOjUT

Current behavior

There is no scroller, thus the user can not see the entire text. Also, the listbox is shifted a little bit to the left.

Expected/desired behavior

There should be a scroller and the entire ListBox should be visible.

The issue is a regression starting with 2022 R1 (2022.1.119) release

Пossible workaround

  
<style>
 .k-list-content{
      overflow: auto;       
}

.k-listbox .k-list-scroller {
      min-width: 0;
}

.k-selected{
        width: fit-content;

Hi Team,

I would like to request a way to utilize formattingMarks for the Kendo UI Inline Editor without having to set inlineHeight.  The way we use the editor requires its height to grow dynamically as the user types text. We usually have around five editors displayed on the screen at the same time, so it is important for us that formattingMarks works correctly across multiple editors on a single page.

Thank you!

Bug report

Reproduction of the problem

The ColorPicker with adaptiveMode enabled throws an error after being destroyed and initialzed

1. Oppen the Dojo - https://dojo.telerik.com/iwXhhhCW
2. Click the ‘Refresh’ button
3. Resize the browser window or the Dojo

Current behavior

An error: kendo.columnmenu.js:2099 Uncaught TypeError: Cannot read properties of null (reading 'attr') is thrown

Expected/desired behavior

No error should be thrown after reinitializing the ColorPicker component.

Environment

• Kendo/Telerik version: 2026.1.415
• Browser: [all ]

1. Navigate to: https://dojo.telerik.com/@PMcDonou/UVIXEPOk

2. Enter a space in maskedtextbox

Result: space is accepted as a valid character 

Expected: space should be prevented

Workaround: Use '\u2000' for promptChar instead of space

Bug report
DateTimePicker modern type cut does not flip popup when there is more space above the input

Reproduction of the problem

Open this example:

Resize the window so vertical scrollbar appears

Scroll so the DateTimePicker is below the center of the window 

Open the DateTimePicker

Expected/desired behavior
Popup shall be positioned on top of the input

We're using the kendo spreadsheet with validation.

There's a cell that validates against a list of values.

The list of values can be up to 50 values or so.

It would be beneficial if there is a scrollbar for the dropdown, similar to the Excel behavior.

Problem There's no way to display milestones that apply across the entire Gantt independent of the task hierarchy. Tying milestones to task rows means they disappear when rows collapse, and sibling-row workarounds are visually indistinguishable from real content rows.

Requested Behavior A pinned milestone band rendered above the task rows, below the timeline header, that:

• Stays visible regardless of row collapse state
• Scrolls horizontally with the timeline but not vertically with tasks
• Accepts milestone objects with date, label, color, and type
• Supports multiple milestones on the same band (stagger or tooltip on hover)

Use Case In our publication planning workflow, study-level dates (Data Lock, Embargo Lift, Interim Analysis) are reference points that need to be visible while scrolling through 20–50 task rows. These don't belong to any single task — they're plan-wide context.

Proposed API

globalMilestones: [
  { date: new Date("2026-03-01"), label: "Data Lock", color: "#F58010" },
  { date: new Date("2026-05-15"), label: "Embargo Lift", color: "#20B34A" },
],
showGlobalMilestoneBand: true,
globalMilestoneBandHeight: 32

Hi Team,

I would like to request a way to prevent a responsive Grid from displaying an input when the screensize/container is shorter.  Perhaps, decreasing the buttonCount automatically instead of displaying the input may be a reasonable alternative.  This would be better than setting the pageable.responsive configuration to false.  

Thank you!

When you have a simple kendodropdown list that is set to adaptiveMode = "auto", resizing the browser throws. This can be reproduced on your demo pages.

Steps to reproduce:

1. use this Dojo: https://dojo.telerik.com/LHJLQgzy which was created from your demo page
2. Ensure the browser is narrow enough to be considered mobile
3. run the project
4. confirm dropdown is functional
5. resize the browser to desktop size
6. the dropdown list stops working and throws

kendo.virtuallist.js:2890 Uncaught TypeError: Cannot read properties of undefined (reading 'style')

Hi Team,

Background

Kendo controls column width exclusively via <colgroup><col width="Npx"> attributes. CSS min-width on <col> is not supported by browsers (per spec). There is no minWidth property in the column configuration API. When a column has no explicit width set, it can collapse to near-zero width when the grid container is narrow - making content completely unreadable. This request excludes the columns.minResizableWidth as resizable is necessary with this configuration.

Request

We need the following to work generically across all grids without per-instance config changes:

1. Column minWidth API

columns: [
  { field: "name", title: "Name", minWidth: 150 }  // ← requested or it would be great if this min width we can apply at global level
]

Where minWidth is respected even if no width is specified, and is not overridden if an explicit width larger than minWidth is set else the global min width of 150px should be considered.

2. Grid-level minWidth config

$("#grid").kendoGrid({
  minWidth: 1000  // ← requested: grid never renders narrower than this or columnCount * default columns global width (150px) whichever is higher
});

Or ideally computed automatically as Math.max(1000, columns.length * defaultMinColWidth).

Hi Team,

What we're looking to achieve, is that when the page/grid enters edit mode, ALL fields in the grid should immediately become editable fields. This would help prevent the user from having to click on every cell to edit first, and the user would have a direct view of all fields actually being editable, make their changes, hit the save button on the page, and save everything at once.

Currently it's difficult for the user to actually know which fields they can edit, as they have to click a cell before it becomes editable.

Thank you!

When the timezone of the machine and the timezone set in the Scheduler are in different days, the currentTimeMarker is not displayed in the Timeline view.

Reproduction of the problem

1. Change the timezone of the machine to 'Fiji' or another timezone, thus the 'Honolulu and the chosen timezones are on different days. For example, when it is 3 am on 01.06 in Honolulu, it is 1 am on 02.06 in Fiji.
2. Open the Dojo linked here where the timezone is set to 'Pacific/Honolulu' - https://dojo.telerik.com/@NeliKondova/UVuDAJib

Current behavior

When the timezone of the machine and the timezone set in the Scheduler are in different days, the cusrrentTimeMarker is not displayed in the Timeline view.

Expected/desired behavior

The cusrrentTimeMarker should be displayed in all the views.
