Hi team,

In kendo spreadsheet if you disable any row by adding enable property to false and apply sort from data tab, then the disable row is changing based on the sort. instead of applying to particular row  it is applying to perticular range and while sorting the row items are changing. The cell properties are not applying there while sorting.

 

link for example: https://dojo.telerik.com/IkoJeMIz

 

please let me know if I am doing anything wrong here.

 

thanks.

Bug report

Reproduction of the problem

Reproducible in this demo: https://demos.telerik.com/kendo-ui/spreadsheet/datasource

  2. Focus A78 and drag to E78. Copy the data
  3. Paste over the empty 79 row's first cell
  4. Press Ctrl + Z to undo the changes.
  5. Open the browser's dev tools network tab and press the "Save" button above the Spreadsheet.

Expected/desired behavior

No data is sent with the request

Provide a mechanism for disabling automatic recalculation of formulas in cells. In order to augment the widget when a large portion of sheets are and cells are rendered.
Completed
Last Updated: 15 Dec 2025 07:08 by ADMIN

Bug report

Reproduction of the problem

Dojo example.

  1. Click column "B"'s header to select the column.
  2. Use the "Wrap text" tool from the toolbar. The text in B2 is wrapped.
  3. While the column is still selected, use the "Wrap text" tool again.

Current behavior

The text in B2 is not unwrapped.

The merged cell prevents the unwrap. If there is no merged cell, or if the tool is used over the cell itself, wrapping/unwrapping works as expected.

Expected/desired behavior

The text in B2 is unwrapped.

Bug report

The AND formula, when used as part of an array formula, does not evaluate the whole array.

{=AND(A1:D1="")} would return TRUE if a value is entered in the range B1:D1 and FALSE only if value is entered in A1
=IF(AND(A1="",B1="",C1="",D1=""),TRUE,FALSE) would return FALSE if value is entered in any cell in range A1:D1

Reproduction of the problem

  1. Run this dojo
  2. Select cell E1, press F2 to edit formula and press Ctrl+Shift+Enter to enter as an array formula

Current behavior

  1. Enter a value in cell B1 - Array formula evaluates as TRUE, Non-array formula as FALSE
  2. Only if a value is entered in A1 the Array formula will evaluate as FALSE

Expected/desired behavior

Array formula should be evaluated correctly and return FALSE when a value is entered in any cell in range A1:D1.

Dear Concerned,

1. Open https://demos.telerik.com/kendo-ui/spreadsheet/index

2. Move horizontal scroller to column P

3. Now select Row 1 header, then row 2 header and keep doing it

4. Please observe horizontal scroller is also moving towards left

I assume it is a bug and need a fix. Meanwhile if you can provide a workaround for the same if possible.

Note: Similar behavior can be noted for vertical scroller on column header selection
