We use "@progress/kendo-react-treelist": "^5.10.1" in our project. Trees are usually placed in flexible containers, and users can reduce their size to 0. At this point, we get an error when calling the tableRowsVirtualization function. I have attached a screenshot at the moment of debugging. You can see that the values of items[0] and lastItem are undefined when the container size approaches 0. I didn't prepare an example to reproduce the error, because I think it's pretty clear that an error occurs here. So the questions are: if this is a bug, is it fixed in the new versions of the package? If there is a possible error on our part or it has not been fixed in the new versions, then what should we do to solve the problem? Thanks

Hi! 

I have noticed that keyboard navigation doesn't work in the filter editor components inside the Filter component

Reproduction:

1. Open https://stackblitz.com/edit/react-rvwjsm?file=index.html
2. Choose "name" or "price" from the first dropdown
3. Type anything in the input field
4. Try to change the cursor position in the field using arrow keys - doesn't work

 Is there a way to enable it or go around it? 

It would be great if there was an animationClass prop that will make styling easier.

Hi,

The first render of a DatePicker component with an onOpen prop throws an error: Unknown event handler property `onOpen`. It will be ignored.

Reproduction:

1. Open https://stackblitz.com/edit/react-xje2zdjc?file=app%2Fapp.tsx

2. The error will appear in the console

Expected behavior:

No errors in the console

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.

The data grid date column "equals" filter should match any datetime within the selected date, not just at time 0:00:00.

Provide a set of utility functions for safely creating, traversing, updating, and deleting filters inside nested CompositeFilterDescriptor trees.

Title, requests formed by the component are sent out with empty payload.

It would be great if there was a way to customize the flag of the Timeline component

It would be beneficial if there was a mechanism to identify the actual grouping level of each header cell regardless of expansion state, such as exposing a groupLevel property

Currently, there is no way to add a header above each view. Therefore, it is confusing when there are many views as it is unclearly what moth is displayed in each view.

• Angular example
  

Please see the example - https://codesandbox.io/p/sandbox/silly-wind-tpfg8n

When column "Unit Price" is locked, while moving the horizontal scroll bar, the group header is sticky (expected behavior), but the group footer is not sticky (wrong behavior).

It would be great to have the Smart Grid functionalities in the TreeList.

I want to achieve an improved customization over the font styling of the title and subtitle pieces using the SCSS theme variables. We want to globalize the style changes via SCSS

It would be beneficial if the ExpansionPanel had allowed adding additional header content outside of the built-in title and indicator elements

It would be great if there was a mechanism for customizing the sorting of the ExpansionPanel headers

Hi team,

Is it possible to have the Enter key press automatically apply the filter when the filter menu is open and active similar to submitting a form?

For example in the Column Menu if I enter some text in the filter the Filter button becomes active, if I press the Enter key nothing happens, for the filter it would be nice if it can submit the filter like for normal forms where the enter key would submit the form.

Another example would be the Checkbox Menu Filter, if I check a checkbox in the filter the current active and focused element is the checkbox and if the Enter key is pressed then it de-selects the checkbox. This behaviour is not very useful, a better implementation would be on Enter press the filter is applied.

Thanks.

In the current implementation of the KendoReact Chart, when a series is hovered, it enters its active state, and the rest of the series enter their inactive states. It would be great if the Chart supported disabling this behaviour, so that hovering over a specific series does not trigger the inactive states of the other series.

I have a tile with the reorderable prop set to false. If I resize the tile the drag clue is rendered (the hand pointer). 

If TabStrip animation is set to false, TabStripTab content width is 100%. If TabStrip animation is set to true (default), TabStripTab content width depends on the content and TabStripTab.contentClassName has no impact on the width of the content.

We should not have to override css classes to set the TabStripTab content width to 100% with animation enabled. As a result we have disabled TabStrip animations everywhere.
