In Excel, you can group / ungroup rows AND columns.  This is particularly useful for income statement reports.  It would be great if Spreadsheet component can support the rendering of groups created in Excel and also allow groups to be created with the component.  

Dear Sir/Madam,

I would like to disable the right part of a split button dynamically, so something like

<SplitButton rightDisabled={true} items={items} text="Disabled Button" />

Obviously, when the value rightDisabled changes to false, the right part should be enabled again.

Regards,

Peter

Hi, Keyboard navigation using "page down" and "page up keys" doesn't work.

Here is a stackblitz where the problem can be reproduced: https://stackblitz.com/edit/react-q9n5fe?file=app%2Fmain.tsx
Reproduction steps:

1. Click inside the grid
2. Press "Page down" or "Page up" - doesn't work

It only works when:

1. Click outside of the grid
2. click on vertical scroll bar without selecting any grid cell.
3. Press"Page down" or "Page up" - it works.

Best Regards

Hubert

I'm in need of the format Year/WeekOfTheYear/DayOfTheWeek for the date range picker. Ex. 2024/44/3, meaning the year 2024 week 44 day Wednesday. 

This is not supported currently, please vote for it's implementation if format support has been an issue for you too.

Our client requirement is they need to modify any dates using datepicker.

For example

if 11/11/2024 need to change 11/12/2024

just a single one digit change is not permitted we need to type 12 which is 2 digit change that means complete day

same happens for month and year as well

We found Carbon-date-picker provides similar functionality which solves our requirement where we can modify each and every digit of datepicker element

A json-file is needed to use localization in Kendo React. It's a lot of work to maintain these files when there are new versions. It's difficult to know which keys have been added, changed or removed.

Hello! Is it possible to not show a room if there is no meeting on that day while simultaneously showing it on a different person because they have a meeting on that day? In the image below, I edited the data so Peter no longer had a meeting in room 2. Is it possible to get it to show Peter with just the meeting room(s) that they has data for, while keeping Alex with all the rooms that they have data for?

Peter -> Meeting Room 1 

Alex -> Meeting Room 1 AND Meeting Room 2

I think this would be a great feature to have. Lets say I have 100 students and/or 100 meeting rooms and all have a different days/times when they are needed. If there was a way to show ONLY what is being booked, or show ONLY what is free, that would be a fantastic feature for users and developers alike.

It would be ideal if toODataString could take an additional parameter that:

1. Takes a collection of expressions,
2. Each expression takes an Operator and Value,
3. Each expression returns a string or undefined, where the latter suggests we wish to suppress this expression.

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

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?
