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

Hi Team,

I would like to request to include the PMT function for the Kendo UI Spreadsheet.

Thank you!

Using a datasource on a sheet

Selecting entire sheet and clicking the filter in the data toolbar tab.

The buttons for the columns do not respect the size of rowHeight or headerHeight

Set rowHeight to 20 and i get this 

We are using a sheet with a datasource

if the user only selects one column and then sorts it only sorts the data in that column and mixes the rows data. 

Suggestion: the filter button should act like the Excel filter button where it auto selects the entire sheet before applying the filter.

Maybe only when using a datasource?

Bug report

When attempting to validate a cell value against a predefined finite list, the validation process fails to recognize valid entries that are present in the list. Instead, it incorrectly flags them as invalid. The issue occur when there is an empty space before the first value in the 'from' option.

Reproduction of the problem

1. Run the Dojo - https://dojo.telerik.com/@NeliK/icizisEF

Current behavior

On the first row, the 'YES' in the B1 cell is marked as invalid although it is present in the list with the valid values. the difference between row 1 and row 4 is the empty space in the validation from configuration:

"from": "{ \"YES\", \"NO\"}", //row 1
"from": "{\"YES\", \"NO\"}" //row 4

Expected/desired behavior

The empty space added in the from configuration option should not affect the validation. If the cell value is present in the list, it should be marked as valid.

The issue is a regression starting with 2020.3.1118
