When there are many items in the menu, the height should not exceed the page size. Now the scroll is not displayed.

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

It refers to version 9.1.0, version 8.5.5 works fine

Thank you

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:

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?

## Missing kendo-react-popup

On this page: https://www.telerik.com/kendo-react-ui/getting-started/

On this section: "Add a KendoReact Data Grid"

When I launch the app as usual:

```sh
yarn start
```

Then the browser page includes this error:

```
Compiled with problems:

ERROR in ./.yarn/__virtual__/@progress-kendo-react-data-tools-virtual-df92d36fcf/0/cache/@progress-kendo-react-data-tools-npm-5.2.0-8d098f65a0-5d68752aaa.zip/node_modules/@progress/kendo-react-data-tools/dist/es/columnmenu/ColumnMenuFilterForm.js 19:0-55

The solution that works for me...

Add the package:

```sh
yarn add @progress/kendo-react-popup
````

Edit `src/App.js` and add this line:

```js
import '@progress/kendo-react-popup';
```

Currently, the onLabel and offLabel properties can only be set to string values. There should be an option that allows setting icons for the Switch component.

Release 2025 Q1 (Feb)

As stated in the subject. To reproduce:

npx create-react-app my-app --template typescript
  • Change the react and react-dom dependencies in the generated package.json file from ^19.0.0 to ^18.0.0, add corresponding "@types/react": "^18.0.0" and "@types/react-dom": "^18.0.0" entries to devDependencies, and add a standard tsconfig.json file e.g.
{
    "compilerOptions": {
      "target": "es6",
      "lib": [
        "dom",
        "dom.iterable",
        "esnext"
      ],
      "allowJs": true,
      "skipLibCheck": true,
      "esModuleInterop": true,
      "allowSyntheticDefaultImports": true,
      "strict": true,
      "forceConsistentCasingInFileNames": true,
      "noFallthroughCasesInSwitch": true,
      "module": "esnext",
      "moduleResolution": "node",
      "resolveJsonModule": true,
      "isolatedModules": true,
      "noEmit": true,
      "jsx": "react-jsx"
    },
    "include": [
      "src"
    ]
  }
npm i @progress/kendo-react-grid @progress/kendo-data-query @progress/kendo-react-data-tools @progress/kendo-react-inputs @progress/kendo-react-intl @progress/kendo-react-dropdowns @progress/kendo-react-dateinputs @progress/kendo-drawing @progress/kendo-react-animation @progress/kendo-licensing @progress/kendo-react-buttons @progress/kendo-react-treeview @progress/kendo-react-popup @progress/kendo-svg-icons @progress/kendo-theme-default
  • Delete content generated by create-react-app which is not required e.g. App.test.tsx, logo.svg, reportWebVitals.ts, setupTests.ts and corresponding references
  • Confirm you can run npm start with no webpack errors or warnings (see screenshot)
  • Add a <Grid> with <GridNoRecords> to App.tsx e.g.
    <div className="App">
      <header className="App-header">
        <Grid>
          <GridNoRecords>This generates TS2786</GridNoRecords>
        </Grid>
      </header>
    </div>

Confirm that npm start results in error TS2786 (see screenshot).

Please see attached for the sample project (with the node_modules folder removed). I believe this error was introduced in v9.0.0 as part of the migration from classes to functional components.

When I press on a day from the past the DatePicker automatically scrolls to the next/previous year. Please check the attached video. 

Is there any workaround for this issue ?

here's a simple repro project minimally tweaked from an original kendo demo:

https://codesandbox.io/p/sandbox/suspicious-lovelace-8nmzgj?file=%2Fpackage.json

just start dragging a column resize handle and you should see the "jitter" right away. in our experience, the jitter is so pronounced that resizing columns is no longer practically usable.

please note this bug is definitely related to putting the kendo grid inside of a css-grid, see that definition in the parent <div style>

as you may imagine, we use css-grid for our overall page layout which i believe is still modern best practice and we really hope you can fix this regression within that usage context.

note, the bug manifests regardless of the gridTemplateAreas or gridTemplateColumns, you can eliminate those entirely and it's still present.

hopefully helpful for tracking down:  it appears this started exactly in version "@progress/kendo-react-grid": "9.0.0-develop.11"... notice if you change back to @progress/kendo-react-grid v9.0.0-develop.10 the columns will no longer jitter upon resize.

Hi,

Please see the following example of the Upload component being used to transfer a single file to a byte array:

https://stackblitz.com/edit/react-u2kbu9?file=app/main.tsx

Notice that all packages are latest including react 18 but I have not switched to the new createRoot API, and as per react documentation "Until you switch to the new API, your app will behave as if it’s running React 17" - this warning can be seen in the console window. When you upload a file, the FileReader onprogress and onload events result in the file being successfully uploaded with 100% progress. You can see current state and new state of all events in the console window.

Now please see the exact same example but switched to the new createRoot API:

https://stackblitz.com/edit/react-y8fuya?file=app%2Fmain.tsx

Notice that the warning is no longer visible in the console window. When you upload a file, the FileReader onprogress and onload events result in the file being successfully uploaded but the file progress is overwritten. You can see current state and new state of all events in the console window - the new state from the onProgress event is lost, and the new state in the onStatusChange event reports zero progress.

I believe this is because of automatic batching in React 18.

Kind regards,

David

Step by step instructions on how to reproduce the problem

Try entering a negative value in the filter column using the StackBlitz example here https://stackblitz.com/edit/react-dx7cna?file=app/main.jsx

 

This works using "ES" as locale (your example) https://stackblitz.com/run/?file=app/main.jsx

We have two issues with grid with virtual scroll.

Both are registered on github.

First one is really blocking us: https://github.com/telerik/kendo-react/issues/1010

Second one we found on Safari, it's also very critical for our customers: https://github.com/telerik/kendo-react/issues/1013

 

Version: 4.7.0. Please note that version specified in Additional information does not make sense as we use Kendo React not Kendo UI.

Can you help us somehow?

When a user focus an empty DatePicker input using tab, the caret starts at the end (right side) of the input.

We need it to start at the left side, so the user can type without having to go all the way back to the left.

here is a quick repro: https://stackblitz.com/edit/react-dfwz3q?file=package.json

in package.json just switch @progress/kendo-react-grid from 4.10.0 back to 4.9.0 and the column menu renders.

bug still present up through 4.11, 4.12, and @latest 4.13
