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

StackBlitz example: https://stackblitz.com/edit/react-vg8pu5?file=app/main.jsx

If you have a Form <Field component={Input}> inside an <ExpansionPanel>, if you press space or enter within the input, the expansion panel also receives the key event and will expand/collapse. It seems like these key events should not bubble out of the Field component.

There is an issue with ComboBox remote virtualization.  This is reproducible on https://www.telerik.com/kendo-react-ui/components/dropdowns/combobox/filtering/#toc-filtering-with-remote-data-and-virtualization

Scroll slowly till almost the end of the list. Pay attention to the name: Paula Parente

Notice that the name keeps repeating after scrolling as the scroll goes back and forth. You'll need to scroll a few times more before the scroll continues to load

other items.

Hello,

There is a very serious bug in the Kendo React date picker component: the month of January is simply not displayed

The issue can be witnessed on your demo page:

https://www.telerik.com/kendo-react-ui/components/dateinputs/datepicker/

Just open the picker and you'll see January is not there

in the kendo UI react chart I need the average line, max line, and min line targeting some value   

Please suggest which features to use with respect to the above requirements, if available.

Steps to reproduce:

1. Create a notification and a button to toggle it
2. Run a screen reader such as NVDA or JAWS
   
3. Toggle the notification to appear

Expected result: The text in the notification is read by the screen reader when the notification appears

Actual result: The notification text is not read out

Add support for complex object array filter of DataSourceRequest.

let dataSourceRequestFilterComplexObjectArray = {
  filter: {
    logic: "and",
    filters: [
      {
        field: "users[name]", // OR with dot notation -> "users[someObject].name"
        operator: "eq",
        value: "Bill"
      }
    ]
  }
};

As present in other Kendo suites:

https://docs.telerik.com/kendo-ui/controls/filemanager/overview 

As per the subject. This can be observed in the following StackBlitz which is forked from the Telerik documentation on resizing with three small changes:

• Remove style={{ height: '400px' }} from the Grid component in app.tsx
• Remove height: 100%; from my-app style in index.html
• Remove height: 100%; from html, body style in index.html

https://stackblitz.com/edit/react-vajzshwv?file=app%2Fapp.tsx,index.html

Logged as a bug because there is nothing in the documentation stating that a height for the Grid or Grid container must be set in order for this to work. If this is a documentation issue rather than a code issue, please advise the recommended approach for using the Grid resizable property.

Hi,

I would like to put forward a feature request to allow the panel bar items to be mounted when the panel bar itself mounts, irrelevant of whether it has been opened or not.

I'm looking for something like the keepItemsMounted property https://www.telerik.com/kendo-react-ui/components/layout/panelbar/mounted-items, but without the condition that a panel bar has to be opened at least once for them to stay mounted.

Hi, when entering https://www.telerik.com/kendo-react-ui/getting-started form npmjs.com, I end up on a page with "Try Kendo UI for React" heading, but whole header comes from Kendo UI for Angular project

The Dropdown section of the components index is described as "The DropDowns allow users to select single or multiple predefined and custom values."
I didn't find a way to select multiple values on any of the components (AutoComplete, DropDown, ComboBox)
