Ability to set a cell with font Strikethrough

Hi ,

we have a requirement to disable comment option on click of few cells (which are disabled) or to show a toastr message on click of comment that user can't add comment on specific cell. Do you have any such feature or event to track this requirement .

By default the items in filter are in random order. Can we sort the items in ascending order by default.

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

Working with numbers like 0.000001056  in a Spreadsheet that is bound to a dataSource, after saving the dataSource, the mentioned number will be converted to an exponential format. 

The current feature request is about preventing the format changing after saving decimal numbers.

It will be very useful if we can use the Spreadsheet with dataSource binding but keep the decimal numbers as such, not converting them to exponential expressions.

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.

Environment

• Kendo UI version: 2020.3.1021
• jQuery version: x.y

Currently, in Kendo Spreadsheet multiple rows/columns can not be selected by using Shift + click. For example, in Excel, if the user clicks on the first column header, then press 'Shift' key and click on the fifth column header all five columns will be selected. The same is valid for row selection.

I would like to have the possibility for multiple rows/columns selection by using the Shift key +click In Kendo UI for jQuery Spreadsheet.

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.

Environment

• Kendo UI version: 2020.2.617

Need:

Extract only the values for all Spreadsheet cells. These extracted values can be sent back to server (with minimum size) as server only needs data on each sheet. On other information required like references, formulas, images, colors etc.

Possible Approach:

On click of save or a separate button, which will generate a low size data file (having sheet name, cell index and value), which we can send to server.

It will save network traffic and also no complex parsing needed at server side to fetch data.

Dear Concerned,

1. open https://demos.telerik.com/kendo-ui/spreadsheet/index

2. select row header of row 10, go to Insert tab

3. click insert row below, it inserts row successfully after row 10, it adjust formulas of row 12, and other rows there after which is good.

4. But issue is - it neither keep format of row 10 in new row & nor it add formulas to various columns in new row(e.g. F11, E11)

Please suggest how can we achieve it, it is very common and useful feature which excel have. if you do not have any ready solution then please suggest workaround for the same as it is urgent for my client.

Hi Team,

I would like to request the Kendo UI Grid to improve performance when evaluating multiple formulas.  At this point, if I use a formula on multiple rows(over 1500 rows), the page slows and eventually crashes.  This happens when I use the fromFile method too.  

Thank you for the consideration!

Bug report

The Spreadsheet doesn't' load correctly Excel files which definition of the tag is a single cell, instead of a cell range.

Test files: test-2.zip

Reproduction of the problem

1. Download the test-2.zip file and load the "test.xlsx" file in the Spreadsheet here.
2. The file has data in the “AZ” and “BA” columns and once it is imported in the Spreadsheet the data from the “BA” column is imported in the “AX” column and the values in the AZ column are missing.

• If the above file is saved in Excel it is correctly loading in the Spreadsheet. In the attached archive there is the “test-copy.xlsx” file which is the saved and correctly working one. Below is the structure of the two files. The one in red is from the "test.xlsx" file and the code in green is from the "test-copy.xlsx" file.

Current behavior

The The "test.xlsx" file is not loading correctly in the Spreadsheet and loses data

Expected/desired behavior

The "test.xlsx" file should load correctly in the Spreadsheet without losing data

Environment

• Kendo UI version: 2020.1.219
• jQuery version: x.y
• Browser: [all]

For the time being the Spreadsheet parser is unable to read files which tags are not in the default namespace. Try to open the attached file in this demo project: https://demos.telerik.com/kendo-ui/spreadsheet/index. 

You won't be able to load the file. If you open the file in Excel, save the file ("Ctrl+S") and try to load it in the Spreadsheet again, there will be no issues with it. The difference in file's structure before and after being saved in Excel could be seen in the attached screenshot.

The code in red is the structure of the file before saving it and the one in green is after the "save" operation. The difference between the files is that the structure of the one saved in Excel inserts the tags in the default namespace while the original document uses the "x:" namespace. 

It will be very useful if we can load files with defined namespaces in their structure.

Reproduction of the problem

Dojo example.

The first row is not duplicated
