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!

Bug report

Spreadsheet validation on datatype=list, values in the dropdown are parsed to numbers. Numeric strings are automatically formatted by removing the heading zero.

Reproduction of the problem

Dojo: https://dojo.telerik.com/eOOvKJxL

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

The bug is a regression, formatting is different with a 2017 version: https://dojo.telerik.com/sCvgBzBa/5

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
