Dear sir/madam,

We noticed an error when setting the "defaultShowWorkHours" to false, it still shows the work hours as the default.
Check the Codesandbox

Expected behavior when you set "defaultShowWorkHours" to false, it shows the full day timeline

As stated in the subject, the GridNoRecords component has an undocumented maximum width of 20em after which the GridNoRecords message is cut off. Please see the following StackBlitz for an example: https://stackblitz.com/edit/react-2z8hh63r?file=app%2Fapp.tsx

Kind regards,

Repro-Steps:
  1. open answers.microsoft.com/en-us/msoffice/ using valid credentials.
  2. Navigate to any article link and hit enter.
  3. Select 'reply' button.
  4. Navigate to 'format' list and invoke it.
  5. Now Run the fast pass using Accessibility Insights for web and observe the failure 'aria input field name'.

Actual Result:
Aria input field doesn’t have an accessible name.

Control type is defined incorrectly as list item for combo box for 'format' combo box.

Expected Result:
Ensure every aria input field should have an accessible name.
Control type should be defined as combo box.

User Impact:
ARIA widget roles require additional attributes that describe the state of the widget. If a required attribute is not provided, the state of the widget will not be communicated to screen reader users.

In Multicombobox choosing combo element using keyboard is broken when data source contains more than one duplicate value of a property used as a textField.

Steps to reproduce:

1. Open https://stackblitz.com/edit/react-afvets8p?file=app%2Fapp.tsx

2. Try to select the 4th value using the arrow keys.

 

It's impossible because there are two items with the name 'Guy Wooten,' and this field is used as the textField.

We have recently added the scrollable prop to our tabStrip component but we are noticing that now on the active tabs there is a line, which is not show when not using the scrollable property. Is there anyway to remove this line? It makes it more difficult in terms of affordance and UX to see that this element is the active tab when there is this line. It somehow breaks the connection between the tab and the content. 


Any help would be appreciated.

When filterable={true} is set, the filter input field does not respond to Home and End keys. The keys are swallowed and never reach the input element, making cursor navigation less convenient.

Steps to Reproduce:
- Render a DropDownList with filterable={true}
- Open the dropdown and type a string into the filter input
- Press Home, End, Shift+Home, or Shift+End

Expected: cursor moves to start/end of input; Shift+Home/Shift+End selects text
Actual: nothing happens in the input field

I have noticed that whenever you want to upload multiple photos at once, using this React Upload Component & Events - KendoReact Docs & Demos (telerik.com) component the previews of the images uploaded bounce/ shake around. I've tried this on multiple browsers and they all have the same bouncing effect for the image previews. For a single photo it doesn't do it but once multiple images are added, it will do it.

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

Actual Result:
After activating the “Workspace to be Saved As in” combo box, keyboard focus moves to the search edit field, while the screen reader focus shifts to the /user control, causing a mismatch in focus.

Refer Attachment:
  1. Screen Reader focus order is incorrect after activating the 'Save to workspace' combo box in windows.png
  2. Screen Reader focus order is incorrect after activating the 'Save to workspace' combo box in windows.mp4

Expected Result:
After activating the combo box, both keyboard focus and screen reader focus should remain in sync and move to the search edit field in a proper sequence.

When typing into a date picker and trying to type Feb 29th, 2024 (or any other leap year ofc) the date is updated incorrectly by the kendo date picker validation. As the user types the year their previous entry of 29 is updated to 28. This should update check should probably not occur until the user is done updating the input. If there is some fix or workaround we can do on our end to resolve this issue please let us know

Here's a video of the bug in our application

However, I was also able to reproduce the exact same behavior even in the documentation:

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?

Issue 1:

I've implemented insert table tool in the editor and I'm setting some states on editor blur. The bug appears when the editor is focused and I try to add a table. When I select the rows and cols from the dropdown  and click to insert the table the editor blur is called my setStates are called and somehow the table insertion doesn't happen. In order to add the table I should not focus the editor and I have to click on the insert table button and select again the cols and rows.

Issue 2:

In the same editor I've added tableResizing plugin. The bug appears when I already have a table in the editor and open the insert table dropdown to add a new one. In that moment when the dropdown is still opened I hover over some of the already inserted table cells borders the insert table dropdown is closed.

Issue 3:

When the editor is controlled we have undefined as initial value and then we type something or try to add table for example the editor crashes and throw an error `Uncaught RangeError: Applying a mismatched transaction`. Even though the value type allows undefined EditorProps.value?: string | Node | undefined. It works fine though if the initial value is empty string.

 

Package
"@progress/kendo-react-editor":"^5.11.0 | 5.12.0"

Minimal reproduction
I'm providing an vite + react + ts project. Steps to run the project:
npm install
npm run dev

It's reproducible in the provided examples in StackBlitz from Kendo, but the editor packages are not always resolved with turbo package manager. I guess it's the same issue as https://github.com/telerik/kendo-react/issues/1530

To demonstrate:

1. Open your simplest interactivity/selection demo, which is not grouped, in StackBlitz. See: https://www.telerik.com/kendo-react-ui/components/grid/interactivity/selection/

2. Add the Grid's group prop. To demonstrate the bug nothing else needs changed

<Grid group={[]} ...

3. Run demo, scroll down and pick a row.

4. Observe the grid scrolls to the top and you cannot see your selected row unless you scroll back.
