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.

Hi Team,

We are using the Kendo Spreadsheet and would like to request a feature to display a character limit indicator while the user is entering data in the cell. This is to prevent users from exceeding the character limit of a cell.

Requirement:

• When the user starts typing in a cell, it should display a live character count e.g. "10/100" if the user has entered 10 characters and limit is 100.
• Once the user reaches the maximum limit (e.g. 100/100), further input in the cell should be restricted.

Thank you!

                      dataType: "list",
                      showButton: true,
                      comparerType: "list",
                      from: "{ \"001\", \"002\", \"Baz item 3\" }",
                      allowNulls: true,
                      type: "reject"

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 emf image support for the Kendo UI Spreadsheet.  If that is not possible, I would like to request a way to handle if the image is in a non-supported image type - such as a console error.  

Thank you!
