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

Kendo version: 2023.3.1010

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!

Hi Team,

I would like to request a built-in way to set a reject type validation when a value is programmatically set in the Kendo UI Spreadsheet.  Currently, it only sets a warning type as shown in this Kendo UI Dojo.  

Thanks!

When a cell is copied to another cell by using the 'auto-fill' option, the format and validation from the initial cell is applied to the target as well, as described in the documentation.

- https://docs.telerik.com/kendo-ui/controls/spreadsheet/end-user/user-guide#other

I would like the possibility to persist the format and validation of the targeted cell and if for example non-valid data is dragged and dropped in a cell, the content to be rejected based on the targeted cell validation. 

Hi Team,

I would like to request to include the Embed function for the Kendo UI Spreadsheet to include objects such as PDF files into the Spreadsheet. 

Thank you!

Bug report

After pasting values from the Kendo UI Spreadsheet to Excel, making a change in Excel, and pasting the value back to a Kendo UI Spreadsheet, it pastes old information.

Reproduction of the problem

1. Open the Kendo UI Spreadsheet Overview
2. Copy Data C7:D8 from Kendo Spreadsheet
3. Paste data to MS Excel (used: Microsoft 365 MSO version 2309)
4. Edit values in MS Excel.
5. Copy from MS Excel
6. Paste new values to a Kendo UI Spreadsheet.

Expected/desired behavior

The new values are not pasted back to the Kendo UI Spreadsheet.

Environment

• Kendo UI version: 2023.3.1114
• jQuery version: All Supported Versions
• Browser: all

Hi Team,

I would like to request the open button for the Kendo UI Spreadsheet's toolbar to fully utilize a Kendo UI Button rather than a native input button.  One benefit would be to help provide a localization message with ease.  

Thank you!

Bug report

When trying to import an Excel document into the Kendo UI Spreadsheet with a missing/corrupt image reference, the file will not show.

Reproduction of the problem

1. Import an XLSX file with a corrupted image into the Kendo UI Spreadsheet demo. (See ticket 1661911 for an example document)

Current behavior

The Kendo UI Spreadsheet fails to load the document.

Expected/desired behavior

The Kendo UI Spreadsheet should handle the error and load the Spreadsheet data without the image.

Environment

• Kendo UI version: 2024.3.806
• jQuery version: All Supported Versions
• Browser: all

As demonstrated here: https://dojo.telerik.com/oFiJOciY

I have the spreadsheet's first row and first column frozen.

I have also made the editor background red, so it is easier to visualize. 

Double click any cell below the frozen parts to enter editor mode, and you will see the editor drift out of its desired rectangle by 2 pixels,

 This is likely caused by the 2px border applied on the k-spreadsheet-pane
