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.

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

Github issue here https://github.com/telerik/kendo-react/issues/897

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

Dear Kendo,

I'm currently working on a data grid that has virtual scrolling enabled. When a user is scrolling fairly quickly, the screen will constantly flash white. See video in attachment.

I see this same behaviour in the example provided in the docs here: https://stackblitz.com/run/?file=app%2Fmain.jsx although it is slightly less noticeable.

What can we do to fix this?

Thanks in advance.

Kind regards,

Peter

How to reproduce (video attached):

1) open combobox
2) scroll to end of the item list
3) select last item 4999
4) open combobox again

Expected behavior: I would like to see the item list.

Actual behavoir: I see white area.

https://www.telerik.com/kendo-react-ui/components/dropdowns/multiselect/virtualization/#toc-basic-configuration 
https://www.telerik.com/kendo-react-ui/components/dropdowns/dropdownlist/virtualization/#toc-basic-configuration 

Current Behaviour

When I lock columns In data grid with resizable columns - for example 1st and 3th and resize the 1st one - after we scroll horizontally the 3th column goes on top of the 1st column. This happens when we haven't set a width prop.

Expected Behaviour

Resized columns not overflowing on each other when scrolling horizontally and don't have width prop.

MInimal Reproduction

I'm providing a reproduction from Kendo React code examples.

Hi,

Not sure what the preferred way to report a problem is. I have posted it on GitHub as well:
https://github.com/telerik/kendo-react/issues/1519

Could someone help me out with this issue?

Thank you in advance.

Hello,

when using the StrictMode we get an UncaughtError when using the PopupComponent. Fe. when using the Date/Time-Picker.

ERROR
Maximum update depth exceeded. This can happen when a component repeatedly calls setState inside componentWillUpdate or componentDidUpdate. React limits the number of nested updates to prevent infinite loops.

Hello,

After updating the kendo version in my project to "^5.1.0" I've noticed that some errors are appearing in our console when we are trying to resize items in the Scheduler. 

"use-resize-item.js:53 Unable to preventDefault inside passive event listener invocation."

I have attached a video with the error.

Thanks!

Hello,

I wound like to customize the column with dates.

Thank you, Matjaz Reberc

Hi Team, 

###Current Behavior

When displaying checkboxes, they are not aligned for nodes with children vs. nodes without children

### Example

https://stackblitz.com/edit/react-rqvush?file=app/main.jsx

### Expected Behaviour

Nodes checkboxes should be aligned the same regardless of if they have children.

###Version

4.8.0

Thanks and Kind Regards,
Grant

Looking at the JSDoc for for `toDataSourceRequestString` and `toDataSourceRequest`, they both appear to have JSDoc above them, showing the parameter as:

 * @param {DataRequestState} state - The state that will be serialized.

Should this actually have `@param {DataSourceRequestState}`?

Given the simple example:

const RatingContainer = () => {
  const [ratingValue, setRatingValue] = useState(0);

  const clearRating = () => {
    setRatingValue(0);
  }

  const onRatingChange = (event) => {
    setRatingValue(event.value);
  }

  return <div>
    <Rating 
      value={ratingValue}
      onChange={onRatingChange}
    />
    <Button
      onClick={clearRating}
    >
      Clear
    </Button>
  </div>
}

export default RatingContainer;

The Rating component behaves as expected when updating `ratingValue` through the Rating component. However, when I want to clear the rating value with the 'Clear' button to update the `ratingValue`, the number of stars displayed doesn't update reflect the value of `ratingValue`.
