    This is a bug on your documentation website.

    Go to for example to see that the side panel on the left is empty in an Edge browser. It flickers then it disappears.

    It works fin in Chrome and Firefox

    Type: Bug Report
    MultiViewCalendar component is broken in your library and in your example pages of it on your website at Clicking the date label in the top left of the control is supposed to change the view level correctly but it does not, it seems to be a click behind in its behavior.

    To reproduce on your site at

    Click on this month label

    Then click any other month than the one you were in

    Then it shows the wrong (previous) month

    If you keep clicking up and down from here you will find it seems to be navigating to your previous click each time, not the current click. Please correct this as its a bug in my new application going to production soon.

    As per the subject, you can no longer use the Calendar to select a date in a month before the currently selected Date. Please see the following demo:

    Steps to reproduce:

    • Click on the Calendar button
    • Click on any month before the currently selected month
    • Click on any date in the month
    • Observe that the day is changed correctly but the month is incorrectly incremented by one

    This error is not observed if you:

    • type in a date
    • use the mousewheel to scroll to the earlier date instead of clicking on the month
    • use Firefox instead of Chrome

    We aren't certain but don't believe this error was present before the latest Chrome 113 update. The error is reproducible in all versions of KendoReact from 5.2.0 onwards.

    On this page:

    There's a syntax mismatch in end-of-line semicolons.

    This line ends with a semicolon:

    import '@progress/kendo-theme-default/dist/all.css';

    This line does not end with a semicolon:

    import { Calendar } from '@progress/kendo-react-dateinputs'

    All teams that I know of consider it to be an error to do both ways in the same file.

    The solution is to pick one way then be consistent. The broader solution is to use a linter, such as ESLint, that can process the code to ensure you're using your expected syntax and formatting.

    AutoComplete focused item is not set correctly if the items are with different height.

    Currently, it is required to have the same height for the items, but this can be very hard in cases when the items are dynamic with various height.

    Hi Guys,

    In GridProps for KendoReact Grid there is an error in the type information:

    Found here:

    In the GridProps.d.ts file it is:

         * Fires when a row is about to be rendered. Overrides the default appearance of the row.
        rowRender?: (row: React.ReactElement<HTMLTableRowElement>, props: GridRowProps) => React.ReactNode;

    This should be changed to:

    rowRender?: (row: React.ReactElement<React.HtmlProps<HTMLTableRowElement>>, props: GridRowProps) => React.ReactNode;


    Note that the React.ReactElement definition is:

        interface ReactElement<P = any, T extends string | JSXElementConstructor<any> = string | JSXElementConstructor<any>> {
            type: T;
            props: P;
            key: Key | null;


    So the first type parameter should be the props typ.

    I noted this while making use of it. After changing it it behaves sensibly. Worked around in my case by using 'as any' to void the type clash.

    I created a solution using KendoReact Editor.

    The editor is set to enable the creation of tables (EditorTools.InsertTable).

    When the property 'defaultEditMode' is set to 'iframe',  the editor inserts a correct table with a width of 100% and visible cell borders.

    If I set the 'defaultEditMode' to 'div' and insert a table the table has a width of some pixels and no borders are shown. In other words, the inserted table is not usable.

    I need to set the editMode to 'div' because otherwise the editor doesn't adjust its look to the other parts of the page. The font is wrong etc.

    How can I get the tables to work in 'div' mode?


    Kind regards

    Add accessibility insights for web extension for edge Anaheim(Dev) browser from

    1. open the given URL using valid credentials.
    2. Select 'reply' button.
    3. Now Run the fast pass using Accessibility Insights for web and observe the failure aria required children.

    Actual results:

    Elements with Aria role is not containing child role with in them.

    Expected results:

    Elements with Aria role should contain child role with in them.


    User Impact:

    For each role, WAI-ARIA explicitly defines which child and parent roles are allowable and/or required. ARIA roles missing required child roles will not be able to perform the accessibility functions intended by the developer.

    Grid Header shifting when filtering column.

    When a column is half visible, and it is filtered, a misalignment will occur between the header and the Grid content.

    DropDownList and MulstiSelect do not open on click(IE 11). 

    They do open sometimes, but it seems random.

    They do open when using the keyboard.

    After updating the kendo version in my project to "^5.1.0" I've noticed that both grid pager dropdown and normal dropdowns won't close when clicked outside if the dropdown is opened using the arrow icon.

    I've attached a video with the issue.

    Is there any workaround for this?

    Hi team, 

    Im not sure if this is a bug or an incomplete feature, so please advise.

    1) TabStrip / Window behavior in v4.8.0 with bootstrap theme 4.40.0, see
    Please note the style and behaviour of the window, its above the modal and can be dragged anywhere on the screen, even though it was rendered from within the TabStripTab component

    2) TabStrip / Window behavior in v4.9.0 with bootstrap theme 4.42.0, see
    As you can immediately see in this example, the TabStripTab heading is also above the modal, an obvious bug
    My concerns are around how the window can no longer be dragged outside the TabStripTab container. Is this by design, beacuse in my use case, my tabs are smaller than my windows.

    Note: I have not tested the windows with any other components.

    Please advise.

    Many Thanks,

    The ListView component has a prop called item that allows you to pass in a custom component for rendering. The type definition for that prop is a component with a props type of "any". The any prop type isn't good here because it's clear there's a structure to these props. Can you please modify this to add a type definition? Thanks.
