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

    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.

    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).

    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.

    3. Verbosity:
      NVDA: Default
      JAWS: Beginner, Highest
      Narrator: Default

    3. Press tab key to navigate to the 'Save As' control and activate it.
    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

    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,

    We are currently developing an application based on Kendo React components.
    We are wondering if the React-Gantt chart has the functionality to edit the data by drag-n-drop the same way it possible with JQuery-Gantt (see attachment).

    Thanks in advance for your help.

     

    Kind regards,
    Sergei

    *** Support ticket created by Telerik by Progress staff ***
    *** Please follow-up with additional details, if necessary. Thank you. ***

    The following options are available in the jQuery version: 

    Insert Comment 

    Insert Hyperlink 

    Insert Image 

    In KendoReact Spreadsheet: 

    These features are currently not available. 

    Query: 

    Are there any APIs or extension points to support these insert operations? 

    Is there a roadmap for introducing these capabilities?

    Disabling the row click selection will be useful In scenarios like multi-row checkbox selection, where the client does not want to update the selection state on row click (but only on checkbox click).

    I would like to extend the functionality of the chart wizard. For example, if I wanted to expose other things to change about the chart, could I create a new tab in the wizard? I would like to allow the user to turn on and off things and I think it makes the most sense to put this functionality next to the other tools editing the chart.
