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.

Hello, 
I am looking to start using the Kendo React grid control, but I need the grid to be responsive to support viewing on a phone. I noticed that your Angular grid has this functionality, but it is missing from your React grid
I would like to have rows turn into individual cards when viewed on a phone. The closest thing I see in the react documentation involves hiding columns, which is undesirable.  Is there a way to add this behavior to the React grid?  If not, when will that be implemented?  
Thank you, 
Alex

ExcelExport has a prop for 'creator'. When the excel file is generated, "creator"'s value is reflected in the file's metadata

For accessibility / screen reader purposes, Title (under Description) must also be populated. Please allow a "title" prop to be accepted by the ExcelExport component.

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

Screen Reader: NVDA (2026.1), JAWS (2026.2603.86), Narrator

Pre-Requisites:
  1. Connect to 'MSFT AzVPN-Manual' VPN.
  2. Turn on Screen Readers:
    NVDA: Ctrl + Alt + N

  4. 'Save As' dialog will open.
  5. Press tab key to reach to the 'Save to workspace' combo box and activate it using enter key.
  6. Verify whether screen reader focus order is incorrect after activating the 'Workspace to be Saved As in' combo box or not.

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.

I would like to request a new Kendo React Grid column editing option so that users can navigate editable columns using the keyboard. This feature should be similar to "navigatable" option from Kendo jQuery grid example - https://demos.telerik.com/kendo-ui/grid/editing

Thanks.

A Wizard Control, allowing any number or steps vertical or horizontal plus ability to modify the look and feel of the steps.  Also the ability to add other controls within each step.  For example a wizard control with the ability to have 3 steps, in which one would have a grid, or scheduler or other components.

Hi, 

I'm in need of the dropdown feature in spreadsheet cells. I had been using the Kendo Spreadsheet React Wrapper which had the dropdown feature but since the latest update to Kendo React Spreadsheet I have been facing issues. Please try to get this feature as soon as possible and I'm sure this will be helpful for other users, too.

Thank you.

    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:

    React Server Components allow the developer to mix the fast server-side rendering with the interactivity of client-side JavaScript. 

    So far modern JS frameworks were explicitly operating on the client (with SSR being an optional feature). With server-components it's the opposite - RS Cs introduce a new mental model for building hybrid applications that leverage both the server and the client.

    The main advantages of the React Server Components are that:

    • Initial page load is faster;
    • You can move the data fetching to the server;
    • You can keep the large dependencies on the server;
    • The client-side JavaScript bundle size is reduced;

      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.

      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.
