GridColumn values property not exists in React version of Kendo grid

I'm migrating KendoUI for jQuery to React. In jQuery version of Kendo Grid was possible to set "values" property to columns with "id" values.

In React version of the kendo grid, the "values" property for the GridColumn component is not available. How can I make the same like in jQuery version?

Thanks a lot for an each help.

How to persist column order and column visibility with ColumnMenu and GridColumnProps?

Problem summary: When including the ability to reorder columns and toggle column visibility on a grid ColumnMenu, the column order gets corrupted despite the correct order being stored and retrieved from session storage.

Detailed description: We want our users to be able to persist their grid column order and visibility. We also want the column order to be updated in the column menu. The column menu context keeps track of the order with a list of GridColumnProps. We save the column menu filter context and the column order into session storage.

Grid

ColumnMenuContext

Session storage

Because GridColumnProps doesn't contain an order index parameter, on our 'onColumnsReorder' event, I take the the GridColumnProps lists and order them based on the orderIndex of the columns passed to the events. This works as expected for when I only reorder the columns or I only toggle column visibility. However, if I reorder the columns and then toggle visibility without refreshing, I lose the original column order. I have verified multiple times in the console that the order being saved to session storage is correct. When I refresh after the column order is lost, it then loads the columns with the correct order.

I've seen this same behavior on other Telerik demos where you set reorderable={true} on a grid with a column menu. Easy steps to reproduce are always to switch the first two columns in the grid, and then toggle the first column's visibility to off. I've included text files (originally tsx files) with our data-grid component implementation and its component dependencies for reference. 'data-grid.tsx' contains the logic for saving the filter order and column order/visibility in the 'onColumnsChange' and the 'onColumnsReorder' event handlers.

If this can't be done with GridColumnProps, is there a different object we could save to the ColumnMenu's lists that would enable direct index tracking?

Only Month or Year views in DatePicker

Hi.

Is it somehow possible to restrict the DatePicker component to only show the month or the year view (see attached screenshots) ?

In my component I have two fields. The first one should only allow a month / year input and the second one should only allow to choose a year. So I would like to use the DatePicker component but as it allows to also select a specific date in a month, that's more than I want to allow to the user.

Thanks,

Greetings,

Bernd

Make filter in multiselect look like filter in dropdownlist

Is there a way to make the filter input (search box) appear at the top of the dropdown list in a multiselect exactly like it does in the dropdownlist component. The expected behavior is this:

User clicks on the dropdownlist (or the down arrow)
The list opens displaying a search (filter) input at the top just like the dropdownlist does.
User types in the filter and the list filters the results.
Each dropdown list item has checkbox for selection
User selects one/multiple items with first item's chip appearing above.
Below is the screenshot for reference

Issue with Content Overflow in Kendo React PDF

Hello,

I am experiencing an issue with Kendo React PDF, as shown in the attached image. The problem is that the last row of content is being shifted to the next page, even though there is some space left on the previous page. This results in unnecessary empty spaces, which affects the overall layout of the document.

Here is a summary of the issue:

Problem: The last row of the table content is shifted to the next page, leaving empty space on the previous page.
Expected Behavior: The content should not leave any empty spaces. If the content overflows, it should be wrapped and split across the pages appropriately.
Issue replication: I've used the sample code provided in the documentation. I've just changed the ProductName in the product.json file.
Replace the last object present in the product.json with the below object.
Here is the link to the demo that I've used https://www.telerik.com/kendo-react-ui/components/pdfprocessing/get-started/

{
    "ProductID": 9,
    "ProductName": "Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku Mishi Kobe Niku ",
    "SupplierID": 4,
    "CategoryID": 6,
    "QuantityPerUnit": "18 - 500 g pkgs.",
    "UnitPrice": 97.0,
    "UnitsInStock": 29,
    "UnitsOnOrder": 0,
    "ReorderLevel": 0,
    "Discontinued": true,
    "Category": {
      "CategoryID": 6,
      "CategoryName": "Meat/Poultry",
      "Description": "Prepared meats"
    }
  }

I would appreciate any guidance or solutions to resolve this issue.

Thank you in advance for your help!

Best regards,
Aman

Excel Export - how to export CellOptions interface

in Kendo excel export version 5, I was able to use the CellOptions interface found in CellOptions.d.ts. This allowed me to create a shortcut const that could be used across my app for standard cellOptions:

import { CellOptions } from "@progress/kendo-react-excel-export/dist/npm/ooxml/CellOptionsInterface";

export const cellOptions: CellOptions = { verticalAlign: "center", textAlign: "center" };
then use it like this:
<ExcelExportColumn field="ID" title="ID" {...columnOptions} width={100} />
 

However, in version 7 (and I'm guessing 8), that CellOptions interface has been moved to index.d.ts and is not exported from the types.

/**
 * The options for the Excel Export cell.
 */
declare interface CellOptions { ... }

Is there some way I can export or use this to create the same kind of shortcut? Thank you.

The custom cell editor fails when setting cell focus on a newly added row.

I saw an example of setting focus on a new row in the table: https://stackblitz.com/edit/react-dym3qj?file=app%2Fmain.jsx. I tried adding a custom cell editor and setting it to focus, but it failed.

page.tsx：

"use client";

The filter pop up of grid move along with the horizontal scroll bar

Hi All,

I used grid with filter, and found that the filter pop up of grid move along with the horizontal scroll bar, This seems a bit strange, can't the filter panel automatically collapse when scrolling?
