Hi there,

I am attempting to utilise the Kendo React ExcelExport component (and in conjunction Kendo UI Spreadsheet component) to be able to export dynamically generated spreadsheets which can do multi-level nested dropdowns on cells, so that our customers who get our spreadsheets can fill in the cells accurately at the point of entry.

Unfortunately the version of the Excel used for these components doesn't support recent formulas, such as SORT, UNIQUE and FILTER which were ok for our Proof of Concept in Excel (Office365 version) but did not work inside the Kendo components listed above.

Could the Kendo components be upgraded to support the latest features of Excel (at least as far as formulas go), this lack of support is impacting our ability to help our customers do remote data entry without additional overhead.

Another example of  the above (which needed additional debug work) was CONCAT vs CONCATENATE, that caught us out for a bit trying to figure out what it was!

Finally, can we make it so exported spreadsheet "sheets" can be hidden as we need a few "preparation" sheets for our data and would be less confusion if it was not visible to the end users.

Thanks for your support on this matter,

Daniel

I would like the occurrencesInRange function from jQuery to be implemented in KendoReact.

This allows calculating collisions with recurring events onDrag or onResize.

It appears the visible elements with the dataItem are available in the SchedulerViewItemsContext props. If this context were accessible with a hook perhaps that would be enough?

Thanks

Any chance you could provide simple sample code (stackblitz ideally) demonstrating how to combine multiple PDFExport's into a single PDF file?

The need to combine comes from wanting page numbering to start at 1 within each individual pdf render.

Totally open to using the lower level exportPDF from the drawing library... perhaps there's a straightforward path to combining the individual DataURI's?  also open to using additional 3rd party npmjs libraries.

I am trying to get the DOM element of a `Popover` via`ref`, but the returned `PopoverHandle` does not expose an `element` prop. (https://www.telerik.com/kendo-react-ui/components/tooltip/api/PopoverHandle/)

Please can you keep the all component handle API consistent by always exposing the underlaying DOM element?

When an item, which has submenu, from the menu dropdown is hovered the submenu appears. But if you click on the hovered item the submenu disappears.

Expected Behaviour

When an item, which has submenu, from the menu dropdown is hovered and then clicked the submenu should stay visible.

MInimal Reproduction

I'm providing a reproduction from Kendo React code examples.

https://stackblitz.com/edit/react-jqhjyv?file=index.js

When the listbox has many items (roughly 200 and growing) the item attribute makes the listbox act slow when you want to click the item.
Even if the item render only returns the same value as not setting the item attribute. It seems like all the items re-render when it gets clicked?

Also in this example https://www.telerik.com/kendo-react-ui/components/listbox/customization/ it is possible to drag and drop a custom item.
But this is not working when we copy exactly the same code from the example. The drag event gets triggered but nothing happens. 
Both lists have items to avoid this bug: https://github.com/telerik/kendo-react/issues/1300

I can post my source code but it is literally the same as the example. When we remove the item attribute the drag and drop works again. 

I'm working with the MultiSelect dropdown.

My issue is that feeding my own search control into the header of the dropdown itself seems to be impossible.

Our design calls for this component, but requires a search input within the dropdown itself. I've tried to insert one as a header, but your control is built in a way that forces the dropdown to close when the header of the dropdown is clicked. Making my attempted customization of the component impossible. From quick testing it seems the other dropdowns are built this way as well. Making components work in the header and footer (without closing the popup) would greatly increase the customizability of the dropdowns. 

It also seems that the current search input within the button can't be removed or changed to readonly. Our design doesn't expect customizable input in the button. It seems that even if you have filtering turned off it still accepts input that does nothing.

The footer cell is not accessible. I cant be navigated with the keyboard and isn't read out by the screen reader.  Ideally, we would have all the attributes that the header and content cells have to make this work in the same way.

Hello,

After updating the kendo version in my project to "^5.1.0" I've noticed that some errors are appearing in our console when we are trying to resize items in the Scheduler. 

"use-resize-item.js:53 Unable to preventDefault inside passive event listener invocation."

I have attached a video with the error.

Thanks!

Add `layout` prop (https://www.telerik.com/kendo-react-ui/components/dialogs/api/DialogActionsBarProps/#toc-layout/) to `PopoverActionsBar`.

It would be useful to add the `title` prop to the `Button` and `Chip` components. So that we get extra information in the default browser tooltip or use the `Tooltip` component for a customized look.

As it happens, none of the existing ways of setting icons in the Button component work with either of the icon libraries we are using, which are:

1. Google Material Symbols, which uses ligatures to select icons rather than class names.
2. Material Design Icons via @mdi/react and @mdi/js, which renders programmatically generated inline SVGs.  These icons technically can be downloaded as finished SVGs for use with the imageUrl property, but only a single icon at a time, which is significantly less convenient than having access to the entire library at once when using the @mdi packages.

Rather than try to separately add specific support for these (and a thousand other) icon strategies, however, you could add support for both (and a thousand others) at once by just having something like an iconJsx property.  It would accept JSX.Element, and whatever it is given gets rendered inside the span.k-button-icon.k-icon.

So you could do something like this...

<h1>How will you attack?</h1>
{/* Google Material Symbols */}
<Button iconJsx={<span className="material-symbols-outlined">local_fire_department</span>}>Fire Breath</Button>
{/* @mdi/react + @mdi/js */}
<Button iconJsx={<Icon path={mdiKabaddi} />}>Target Weak Spot</Button>
{/* A poop emoji */}
<Button iconJsx={<span role="img" aria-label="poop">💩</span>}>Bio Weapon</Button>

To get something like this...

<h1>How will you attack?</h1>
<button class="k-button k-button-md k-button-rectangle k-button-solid k-button-solid-base k-rounded-md">
  <span role="presentation" class="k-button-icon k-icon">

We currently keep an image library for our customers where we allow them to upload images for use in the editor. Our existing implementation uses something called tinymce and MoxieManager. I see that the jQuery implementation has something similar, but it is not included in the react toolset. 

Can we get the ImageBrowser / FileBrowser part of the jQuery Kendo ported over to the react version?

I have attached an image for example.

If you show a Grid with no rows, the Kendo Grid displays a `k-grid-norecords` row. The generated HTML for this is:

<tr class="k-grid-norecords" aria-rowindex="2"><td colspan="5">No records available</td></tr>

If you run Axe accessibility checks (axe-core 4.4.1) against this, it reports:

Impact: critical
Elements must only use allowed ARIA attributes
ARIA attribute is not allowed: aria-rowindex="2"

It seems that according to Axe, this <tr> element should have `role="row"` to make it compliant.

Normal data rows, where there is data, do include `role="row"`. Only the 'no records' row seems to be missing it. Can this role be added?

Currently the MultiSelectTree Component doesn't have Virtualization therefore is unable to provide infinite scrolling.

Please can this be added.

Thank you,

The React Dropdown and Multiselect components are difficult to use in a <Form> because they return an object instead of the value that would be part of a form.

Maybe there is already a way to handle it, but the docs for the MultiSelect do not include any way to map the value Object to just the primitive, and the Form docs have no example with a MultiSelect.

In my experience, when loading and saving data to/from an API, they very rarely take objects with an ID and Text properties. They usually expect just the primitive values (IDs) of the selected items. The Angular MultiSelect control has a `valuePrimitive` attribute that can be used to control this behavior. The React version does not seem to support this use case at all, or it is hard to find in the docs if it does exist.

Example code: https://stackblitz.com/edit/react-xroafa?file=app/main.jsx

Essentially, it would have been nice if you could do:

<MultiSelect
  data={[
    { id: 1, text: 'One' },
    { id: 2, text: 'Two' },
  ]}
  value={[2]} // just a primitive value, not an object
  onChange={(value) => /* value should just be the `id`s not the objects */ }
/>

Which would enable MultiSelect to be usable in a <Form>. Since the <Field> component does not allow overriding the `value` or `onChange` events, mapping these primitives to object form is frustrating and a bunch of extra code.

In the Angular version this is easily achievable, with an example in the docs: https://www.telerik.com/kendo-angular-ui/components/dropdowns/multiselect/value-binding/#toc-primitive-values-from-object-fields
