Hi, 

After pasting a value into the input box of the DatePicker I am then unable to clear it. The value of the DatePicker is correctly set to null, but the value displayed in the input box is unchanged.

Reproduction steps:

1. Open the grid filtering demo,

2. Copy any of the date values from the grid, e.g. 9/20/1996, and paste it into the "First Ordered On" filter,

3. Clear the filter using the clear button.

Result:

The value remains in the input box.

Expected behaviour:

The value should not be visible in the input box.

Test Environment: 
OS: Windows 11 Version 24H2 (OS build 26120.2705)
Browser Edge Version 132.0.2957.55

URL: https://codesandbox.io/p/sandbox/objective-blackburn-jvz3py

User Impact:

Keyboard dependent users will find it difficult to navigate as the focus order is not logical when navigating through the "Upload" controls of bar charts components.

Repro steps:
  1. Open URL: https://codesandbox.io/p/sandbox/objective-blackburn-jvz3py in the latest chrome browser.
  2. Code sandbox page will appear. 
  3. Press tab key from the top of the page to "https://jvz3py.csb.app/" edit field on right side to reach the Bar chart.
  4. Press tab key to move focus between bar charts and press arrow keys to navigate through the bar chart points.
  5. Verify on pressing tab keys whether the keyboard focus order is logical while navigating the "Upload" controls of Bar chart components.

Actual Result:
Keyboard focus order is not logical when navigating through the "Upload" controls of bar charts components in windows. Focus will not move to the 'Upload' button it will move to the next bar graph control.

Refer Attachment: Keyboard focus order is not logical when navigating through the Upload controls of bar charts components.mp4

Expected Result:
Keyboard focus order should be logical while navigating the "Upload" controls of Bar chart components in windows. Focus should move to the 'Upload' button.

The KendoReact Scheduler currently does not provide a supported way to display only all-day events while hiding all time slots when using vertical resource grouping (Week or Timeline-based views). It would be beneficial if we had a mechanism for implementing an all-day–only Scheduler view that supports vertical resource grouping, renders multi-day events as a single continuous bar across consecutive days, and preserves the existing Scheduler structure and interactions.

It would be beneficial for GridToolbarColumnsChooser to offer customization options that allow developers to control which columns can be shown or hidden.

When using KendoReact Grid with multiple grouping levels, the Grid automatically adds horizontal indentation inside <td> elements to represent group hierarchy.

While this behavior is expected, there is no public API to control, customize, or disable this indentation.
As grouping depth increases, this extra space causes layout issues, unexpected horizontal overflow, and breaks strict or custom design systems.

Is there a reason why this spacing is not configurable?
Are there plans to expose an official option (e.g. groupIndent / groupPadding) or any supported API to manage grouped row indentation?

The Data Grid does not work properly with large datasets. In the example below with one million records, it is impossible to scroll to the bottom of the grid.

Firefox: Rows fail to render after scrolling past approximately 200,000 rows.

Chrome: Rows do render, but the skip parameter never exceeds 745,645 even when the scrollbar is at the bottom, preventing access to the remaining ~254,000 records.

This contradicts the documentation's claim that the grid "scales from hundreds to millions of records while maintaining a responsive user experience."

Be able to to modify the cut-off point depending on what baseUnit is selected in a chart time series.

e.g.

Given the following data points:

Data = [

  Friday 10th Oct: 123,
  Saturday 11th Oct: 54,
  Sunday 12th Oct: 77,
  …,
  Tuesday 20th January: 10,

]

If baseUnit = year

Currently what happens is:

1st Jan -> 1st Jan -> 1st Jan

What we want:

10th Oct -> 10th Oct -> 10th Oct

If baseUnit = month

Currently what happens is:

1st Oct -> 1st Nov -> 1st Dec

What we want:

10th Oct -> 10th Nov -> 10th Dec -> etc

*Edge case of 29th, 30th, and 31st:

Default to last day of the month

Oct 31st -> Nov 30th -> Dec 31st

If baseUnit = week

Currently what happens is:

Sunday 5th Oct -> Sunday 12th Oct -> Sunday 19th Oct

What we want:

Friday 10th Oct -> Friday 17th Oct -> Friday 24th Oct -> etc

If baseUnit = day

This is our minimum unit so everything works

In our software we want to create a filter with MultiSelectTree. The hierarchy is this: LV1 -> LV2 -> LV3. In the database the data is assigned to LV3. If the component is loaded with lot of LV3 items then selecting the parent LV2 node will result a very long tag list in the textbox part of the MultiSelectTree which is not user friendly. In this case I expect selecting the LV2 node will check the LV3 subnodes also but the textbox part has only that LV2 tag as selected. So the checkboxes should remain the same textbox should display the selected parent only.

Other cases:

- when LV1 is selected, then every children will be checked but textbox should display only the selected location

- when 99 of 100 LV3 items are checked then LV2 parent is not fully checked so textbox should display only the bins but only the first N items then use ... characters.

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

We should enable the Treelist not to count items on the second level.
