I'm submitting a...

  • Bug report

Current behavior

Timepicker component in adaptive mode behaves differently in version 11.0.0 (and above) compared to version 10.0.0 (and above):

  • "Set" button sets value but does not close popup - one more click needed
  • "NOW" button scrolls to current time, but does neither set value nor close the popup - two more clicks needed
  • in the top right corner there is a button with check icon which does the only thing - closes the popup (the same as "Close" button) - it is confusing

Expected behavior

We would expect the same behavior as in the 10.0.0:

  • "Set" button sets value and closes the popup
  • "NOW" button scrolls to current time, sets value and closes the popup
  • there are no two buttons with the same functionality

Minimal reproduction of the problem with instructions

  1. Please run following link: https://stackblitz.com/edit/react-j3smansk?file=app%2Fapp.tsx,package.json and adjust app container width so that the timepicker popup is rendered in the bottom half of the screen, allowing both the popup and the editor to be visible at the same time. 
  2. Repeat previous step for following link: https://stackblitz.com/edit/react-ukfuqrdy?file=package.json,app%2Fapp.tsx
  3. As you can see in "app.tsx" examples are very the same (taken from https://www.telerik.com/kendo-react-ui/components/dateinputs/timepicker/adaptive-rendering), only versions of kendo-react components in "package.json" are different
  4. Observe situations described in Current behavior and Expected behavior sections

What is the motivation or use case for changing the behavior?

We would like to upgrade to 11.0.0 but we do not like this behaviour because it is disturbing, confusing and requires more clicks (time) to work with it.

Environment

Browser:

  • Chrome (desktop) version 138.0.7204.50 (Official build) (64-bit)
  • Firefox version 140.0 (64-bit)
  • Edge Version 137.0.3296.93 (Official build) (64-bit)

System:

  • TypeScript version: KendoReact demos page version
  • Node version: KendoReact demos page version

Hello,

there are numerous problems with navigating / scrolling on the DataGrid using keyboard keys.

Here is the test page:

https://stackblitz.com/edit/react-brdhufzd

 

1. Grid with navigatable=true:

- arrow keys - when you select a cell to be able to navigate and then  keep pressing down and then up, it's not posible to come back to the first record. You need to use the mouse.

- Page up/down keys work the other way round, also sometimes is not possible to come back to the first record, the scrollbar does not show the current position.

- It starts to work correctly after using the arrow keys and page up/down keys alternatively couple of times

2. Grid with navigatable=false:
- arrow,Page up/down keys and scrollbar work correctly

3. Grid with navigatable=true and nested inside Window:
- works the same way as not nested - the same problems occur

4. Grid with navigatable=false and nested inside Window:
- arrow keys move the window instead of navigating the grid
- Page up/down don't work at all

In Multicombobox choosing combo element using keyboard is broken when data source contains more than one duplicate value of a property used as a textField.

Steps to reproduce:

1. Open https://stackblitz.com/edit/react-afvets8p?file=app%2Fapp.tsx

2. Try to select the 4th value using the arrow keys.

 

It's impossible because there are two items with the name 'Guy Wooten,' and this field is used as the textField.

I am using KendoReact 10.2 and I am getting several warnings about deprecated Sass methods and syntax including one that is causing an error in the browser and blocks rendering. I used the sass-migrator to try to migrate these methods.

Please upgrade KendoReact so it can work with the latest Vite, React and scss/sass packages without deprecation warnings and errors.
Also fix the React version dropdown in this feedback form. It doesn't show React 19 as an option.

Several months ago, I used this example to hide the default row detail expander, and implement my own custom expander:

https://www.telerik.com/kendo-react-ui/components/knowledge-base/custom-expand-collapse-column

As you can see, it seems that some upgrade along the way has broken the example, and it now shows two expander columns. This is also happening when i attempt to upgrade the version in my project. Can this be fixed, or is there a new workaround?

Description

PivotGrid does can not export all the date to excel when the nodes are collapsed

Plan

KendoReact Free

Steps To Reproduce

https://www.telerik.com/kendo-react-ui/components/pivotgrid/excel
Configure a PivotGrid with multiple row and column fields, and at least one measure.

Expand only a few nodes manually.

Click the Export to Excel button.

The exported file contains only the visible/expanded rows/columns.

Screenshots or video

No response

Actual Behavior

It is not practical or user-friendly to expect users to manually expand every node (especially if data changes frequently).

Users expect complete data export based on the selected dimensions/measures and based on provided data source to generate pivot grid — not just what is visible.

Expected Behavior

Expected Behavior:
When clicking Export to Excel, PivotGrid the entire dataset should be exported in expanded format.

Browser

Chrome, All

Browser version

latest

We have recently added the scrollable prop to our tabStrip component but we are noticing that now on the active tabs there is a line, which is not show when not using the scrollable property. Is there anyway to remove this line? It makes it more difficult in terms of affordance and UX to see that this element is the active tab when there is this line. It somehow breaks the connection between the tab and the content. 


Any help would be appreciated.

As per the subject. This can be observed in the following StackBlitz which is forked from the Telerik documentation on resizing with three small changes:

  • Remove style={{ height: '400px' }} from the Grid component in app.tsx
  • Remove height: 100%; from my-app style in index.html
  • Remove height: 100%; from html, body style in index.html

https://stackblitz.com/edit/react-vajzshwv?file=app%2Fapp.tsx,index.html

Logged as a bug because there is nothing in the documentation stating that a height for the Grid or Grid container must be set in order for this to work. If this is a documentation issue rather than a code issue, please advise the recommended approach for using the Grid resizable property.

2. try to input a date by typing 09, then 03, then 2025

Expected behaviour:

The date in the input field should be "09.03.2025"

Actual behaviour:

The date in the input field is "day.09.2000"

When I change the width of the component, I expect that the state of the buttons (active/locked) will change depending on the scroll position, but this does not happen. For example, if the component did not scroll and both buttons are locked, then when the width is reduced, they will also remain locked. I think this is a mistake. Is there a way around this problem?

    in latest v9.3.1 it appears GridFilterCell isn't passing properties shaped as 'isRequired' on DatePicker popupSettings 

    this does seem to be a regression because i just recently noticed it in latest upgrade which we need for other bug fixes.

    i pursued patching myself by populating animate in GridFilterCell.mjs which seemed to work but then i got warning for the next required property "appendTo". however, populating appendTo yields warning "Warning: Failed prop type: Invalid prop `appendTo` supplied to `Kendo React Popup`. Validation failed." so it's not easily reconcilable that way... therefore i tried removing isRequired on all 3 DatePicker popupSettings properties which of course avoided warnings and i didn't see any negative side effects.

    here is a codesandbox repro minimally tweaked to include a date field from kendo grid's "getting started" demo: https://codesandbox.io/p/sandbox/cool-sanne-d4tp85

    admittedly this is just a warning but it does create unnecessary noise in browser debug which detracts from issues truly requiring attention during development.

    screenshot with the warning from that demo repro:
