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.

While testing the TaskBoard component , I encountered several issues: (1) simply dragging cards sometimes causes a crash with Cannot convert undefined or null to object, (2) during drag-and-drop the bottom of the board flickers, (3) a horizontal scrollbar appears inside columns unexpectedly, and (4) cards sometimes disappear or leave visual artifacts (ghosts/shadows) while dragging between columns), and (5) in some cases cards get stuck and it becomes impossible to replace or move them; all of this happens with minimal/default setup, suggesting problems in internal drag-and-drop or state handling.

Hi,

I am trying to implement in-grid date-range filtering using a custom filterCell in KendoReact Grid.

Context:
I followed the Knowledge Base article:
React Create a Date-Range Filter in the Grid - KendoReact

I adapted the example to my project and used a custom filterCell for date-range filtering.
However, I noticed an issue:

When two or more columns with the same custom date filter cell are adjacent, the filter UI of the neighboring columns is rendered inside the first column's filter cell.

Example:
app.jsx - nodebox - CodeSandbox
When column order is: [text, text, date, date, text] - The filter UI of both date columns is rendered inside the first date column.
When I change the order to: [text, text, date, text, date] - The filters render correctly and independently.

Thank you.
Bohdan

When I use minHeight and minWidth for window these props just don't work, even I add these props for inline style in Window component.

Hello!

I'm using KendoReact PDFViewer and I've encountered a problem with the URL prop not working with regular HTTP URLs, for example:

<PDFViewer url="https://example.com/sample.pdf" />

The PDF simply won't load.

Please help:

In what cases does the URL prop actually work in PDFViewer?

Hi!

Is there any reason why element with XXX text is not highlighted just as other elements in 'opened hierarchy'?

Thanks!

Hi Team, 

We have a KendoReact Grid where (effectively) all rows are in edit mode (we set edit so each valid item is editable). One of the editable columns uses a custom edit cell that renders a NumericTextBox (quantity).

We also have a toolbar with an Input used to search/filter products. The toolbar Input onChange is debounced (lodash debounce), and on each debounced change we update the Grid filter/state.

Problem: when the debounced toolbar Input triggers a state update and the Grid re-processes data and re-renders rows, SOMETIMES one of the quantity NumericTextBox inputs auto-focuses. This steals focus from the search input while the user is still typing. The user then unknowingly continues typing, but now their keystrokes go into a quantity cell instead, causing incorrect quantities / incorrect lines ordered.

This is a serious UX/data integrity issue because users can accidentally edit quantities while they intend to keep typing the product search.

Expected Behaviour
When the user is typing in the toolbar search Input, focus should remain on that Input across Grid state changes (sorting/filtering/paging), and no cell editor should automatically take focus unless the user explicitly clicks into a cell or we explicitly programmatically focus it.

Source
I've tried to duplociate the error using a simplistic kendo example without luck but I've included the LineItemsGrid, LineItemsToolbar and the QuantityEditCell in this stackBlits for ref, see `MyFiles`. Note that this is NOT a working demo. There is just too much going on contextually to make a static working demo.

https://stackblitz.com/edit/react-2bkcpcjg?file=MyFiles%2FQuantityEditCell.tsx,MyFiles%2FLineItemsToolbar.tsx,MyFiles%2FLineItemsGrid.tsx
Any advise or way to tweak out where the bug could be would be helpful.

Thanks,
Grant

1. Scroll down a bit so that skip is != 0

2. Add a new item to the start of the list

3. Scroll up, the Grid becomes blank.

Hi,

I noticed that grid column becomes not resizable when using tooltips in grid, even if thProps are passed.

I edited stackblitz of this official example:
React Render Tooltips for Grid Cells - KendoReact

got:

Is it a bug or am I missing something?

Thanks,
Bohdan
