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).

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

Bug report

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

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.

Reproduction of the problem

1. Open a Notepad, and create the following structure:

a
b[tab]c[tab]d
e[tab]f[tab]g

Between each element on rows 2 and 3, there is a [tab] character. This will make sure that the data pasted into Spreadsheet will land on different columns.

 2. Copy the entire content of the Notepad document and paste it in cell A1. After the paste operation, you will notice under the Spreadsheet component an output with the range that was passed to the change event.

Problem:
The computed range is A1:A3 while the expected value is A1:C3

Expected behaviour

The expected value is A1:C3

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

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.

Once I showed this control to a few people they loved it and are asking me to make a lot of interfaces with it.
All of these are databound. 
They want some validation, like dropdown lists, datapicker, etc. And I found you can put controls in cells.
But what do I do with hundreds of rows? In the rows/cells there is validation and editors that can be setup.
For databound sheets, the columns would be a more logical place for validation and editors.

I did find this today, prepping for this request,  https://docs.telerik.com/kendo-ui/controls/spreadsheet/custom-editors

But that is not intuitive.

I'd like for the same validation and editors that are available on rows.cells to be available at sheets.columns when the sheets.dataSource is used.

These would be applied to the columns on the data rows created from the datasource.

Example formulas that should work (Table1 is a named reference of a table):

1. =Table1[Column2] is not working in kendo 

2. =Table1[#Header]  -- Header, Data, All and all other specifiers.

3. =[@ColX] also not working .
