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

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

Bug report

Spreadsheet fromFile() method does not return reject promise when an error occurs while loading file. An error is thrown on the browser console instead.

The issue has been tracked to the following implementation in the source:

  • In the spreadsheet/workbook.js, the method fromFile() rejects the promise only when no file has been passed to the method code
  • In the spreadsheet/excel-reader.js the method readWorkbook() should receive the deferred object as its last argument, but is renamed to progress and never used in the method;

Reproduction of the problem

  • On the following Dojo select invalid file in the file input (.png, .pdf, .jpg or other);

Expected:

the 'No file to be loaded!' should be alerted;

Actual:

An error will be thrown on the console
