Currently, there is a KB that demonstrates how only values can be pasted into the Spreadsheet. However, to achieve pasting values the cells are modified programmatically, which leads to an improper undoRedo stack. In the knowledge base article if the user presses 'Undo' then a single cell will be undone. 

We can add the editing of the cell using commands as demonstrated below, but this will require the user to undo the changes cell by cell and not the entire range at once:

spread._workbook.execute({ command: "EditCommand", options: { value: value, operatingRange: range, editRange: range}});

I think that it will be a good improvement if the Spreadsheet can be configured or if it provides a method that will allow paste-only values that will be properly added to the undoRedo stack and without additional customizations. 

Regards

Bug report

When values are pasted in the Spreadsheet if the cell is not empty the previous format is taken into account

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/@NeliK/IniJunuZ
2. Paste content that contains different formats such as dates and numbers (sample file attached)
   test_format.xlsx
3. Paste the content two times as the second time the number column should be pasted over the column that has dates

Current behavior

The number column is formatted as date - screencast(https://somup.com/cZeoodChyH)

Expected/desired behavior

The current format should be applied to the pasted data.

Environment

• Kendo UI version: 2024.1.130
• Browser: [all ]

Bug report

Modified date value from Excel is not correctly updated when pasting in the Spreadsheet.

Regression introduced with 2023 R1

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/AZateGoC/6
2. Copy the Spreadsheet content
3. Paste in to an Excel file
4. Change the date cell value
5. Copy and paste back in the Spreadsheet

Current behavior

The updated date cell is not pasted in the Spreadsheet

Expected/desired behavior

The updated cell's value should be pasted in the Spreadsheet

Environment

• Kendo UI version: 2024.1.319

Scrolling to a column that is not visible initially and using the Freeze Panes tool, makes the scrollbar of the Spreadsheet unusable. This valid for both horizontal and vertical scrolling. It is observable in the demos: https://demos.telerik.com/kendo-ui/spreadsheet/index

Scroll right to the "R" column. Select it and click on the the "Freeze panes" tool in the toolbar.

Alternatively, scroll down to row 30. Select a cell and click on the the "Freeze panes" tool.

As a result, scrolling the columns (respectively the rows) becomes impossible.

Consider a way to enhance the Freeze panes functionality, so that is is usable in these scenarios.

Hi again :)

I see that in the configuration I can specify the max number of rows/column. However, I can do it per component basis, and I would like to have that on a per-sheet basis. Any way I can implement this?

Thanks!

Describe the bug

To reproduce
Steps to reproduce the behavior:

1. Go to https://dojo.telerik.com/avuXEJUV/2
2. Scroll the Spreadsheet horizontally to the "J" column.
3. Click the header of the "J" column to select it.
4. Activate the "Freeze Panes" tool from the toolbar.
5. The Spreadsheet re-renders. The scroll bar does not scroll the columns past "G". A browser scrollbar appears. Use it to scroll horizontally beyond the right border of the Spreadsheet. Some of the columns are displayed outside the Spreadsheet. Once they are visible, scroll horizontally to the far right using the Spreadsheet scrollbar. Column A is duplicated after column AX.

Expected behavior
The panes are frozen without breaking the layout of the Spreadsheet and without cells/column duplication.

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

Environment

• Kendo UI version: 2024.2.514
• Browser: [all]

Bug report

Round Function from empty cell shows #VALUE! but in Excel, this shows 0

Reproduction of the problem

Open Dojo: https://dojo.telerik.com/aBOMoCOF

Paste in cell B1 the following formula: =ROUND(A1, 2)

The shown result is #VALUE!

In Excel the same formula returns 0

Expected/desired behavior

The shown value must be 0

Environment
Kendo UI version: [all]
Browser: [all ]

Bug report

When the formula PRODUCT is used and the content of the cell based on which the formula is calculated is deleted, the result is incorrect.

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/@NeliK/OKAQaGOv
2. Delete the content of the A1 cell

Current behavior

The result in B1 is 1, while it should be 0

Expected/desired behavior

When the content of the cell used for calculation is deleted, the product formula should result to 0 (as it is in Excel).

Environment

Bug report

When the Spreadsheet height is greater than the page height and the user scrolls and than enters a value in a cell, the Spreadsheet scrolls to the top.

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/@NeliK/EcUYewiH
2. Scroll down the scroller of the page and enter a value.

Current behavior

The Spreadsheet is scrolled to the top. screencast - https://go.screenpal.com/watch/cZj220V9U6j

Expected/desired behavior

The Spreadsheet should persist the position.

The issue is a regression starting with 2022.1.119 version.

Environment

• Kendo UI version: 2024.3.806
• jQuery version: x.y
• Browser: [all | Chrome XX | Firefox XX | IE XX | Safari XX | Mobile Chrome XX | Android X.X Web Browser | iOS XX Safari | iOS XX UIWebView | iOS XX WKWebView ]

Currently, Kendo UI for jQuery Spreadsheet does not support many events such as style change, merge, unmerge, image insert, font change, alignment change, decimal change, filters and more.

But these events need to be captured in many cases.

Please support events for all the actions.

Currently, when an invalid validation formula is used, the Spreadsheet throws a js exception.

For example: https://dojo.telerik.com/AWEyIHoW

Open the Data/Data Validation dialogue on cell A3 and modify the Value of the Formula into an Invalid formula (e.g. : “>3”)

A parse error is thrown.

It would be a nice improvement, if instead of throwing a js exception, the user is notified about the invalid formula through a dialog showing a relevant message.

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

When there is formatting and decimals are rounded negative numbers that round to zero show a negative sign. In Excel those are shown without the negative sign.
