Border disappears after deleting a row (reproducible with simple steps)

[Merlin]

Hello Kendo UI team,

We are using Kendo UI for jQuery Spreadsheet and have encountered a border rendering issue that can be reproduced with a very simple setup and no custom configuration.

---

Reproduction steps

1. Initialize a basic Spreadsheet with default options.

2. Select the range A1:C3.

3. Apply borders to the selected cells (for example, all borders).

4. Select row 3 and delete the row.

---

Actual result

After deleting row 3:

• The top border of cell B1 disappears.

• Other borders remain unchanged.

• The final border state becomes visually inconsistent and unexpected.

The attached screenshots (step1 → step4) show the full process and the resulting issue.

---

Expected result

• Borders explicitly applied by the user should remain intact.

• Deleting row 3 should not affect the top border of B1, since that cell is not part of the deleted row.

---

Request

Is there any solution or workaround for this behavior?

Thank you very much for providing such a powerful and well-designed UI library. We really appreciate the work behind Kendo UI and would love to continue using the Spreadsheet component.

Hi Merlin,

Thank you for the detailed information on the issue.

As there is also a ticket reporting the same behavior I have replied there and have logged a bug that can be tracked in our repository:

https://github.com/telerik/kendo-ui-core/issues/8426

If you have additional inquiries, I suggest we continue the conversation there. That said, I will post an update here when there is a resolution so it can be publicly visible.
