Hi there,

When a spreadsheet is linked to a datasource, if you leave a gap between previously entered rows and your new data, each cell edit creates a new item in the datasource with only the cell modified.

Here is the record after adding one cell.

and after adding another cell:

This is the state of the spreadsheet:

I managed to replicate this in dojo here: https://dojo.telerik.com/eRiHocar

Bug report

When you copy a formatted cell with value "0", pasting the content in the Spreadsheet results in an incorrect value in the formula input.

Reproduction of the problem

1. Open the attached file in the Spreadsheet.
   CopyPaste-CellFormatIssue.xlsx
2. Open the attached file in Excel.
3. Copy the content from C3 to C5 and paste it in the Spreadsheet.

Current behavior

The value of the cells containing "-" are incorrectly changed to "-" in the formula bar.

Expected/desired behavior

The value of the cells containing "-" should remain "0" in the formula bar.

Environment

• Kendo UI version: 2021.2.511

Bug report

When the Sheetsbar is hidden the horizontal scrollbar is not adjusted to the bottom of the widget

Reproduction of the problem

1. Run this dojo
2. Note the space below the horizontal scrollbar:
   

Expected/desired behavior

The horizontal scrollbar should be adjusted to the bottom of the widget.

As a possible workaround, when hiding the Sheetsbar add the following styling:

<style>
    .k-spreadsheet-sheets-bar {
      padding: 0;
      border-style: none;
    }
</style>

Environment

• Kendo UI version: 2021.2.511
• Browser: [all]

The spreadsheet currently relies on the <v> tag and doesn't accept cell type "inlineStr". Here is an article with more info regarding the inlineStr type:

https://c-rex.net/projects/samples/ooxml/e1/Part4/OOXML_P4_DOCX_c_topic_ID0E1XM4.html 

A cell of type "inlineStr" which is currently not accepted in SpredSheet

<c r="F2" s="4" t="inlineStr">
        <is>
          <t>1005131528</t>
        </is>
      </c>

while the format saved from excel is accepted:

<c r="F2" s="2" t="s">
        <v>12</v>
      </c>

Ticket ID: 1517963

To reproduce
Steps to reproduce the behavior:

step1: Make a cell become wrap text and text something

step2: Export to pdf file:

Expected behavior
Text display same as on safari

Please fix this problem asap!!!.

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.

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

Spreadsheet throws error when opening a xlsx file containing diagonal borders.

Reproduction of the problem

1. Try to open a xlsx file, containing a cell with diagonal borders:
   
   Sample File:
   DiagonalBorderTest.xlsx

Current behavior

Spreadsheet crashes and throws an error Uncaught TypeError: Cannot set property 'color' of undefined

Expected/desired behavior

The file should open.

Environment

• Kendo UI version: 2021.1.330
• Browser: [all]

Currently, when working on a mobile device, the Spreadsheet doesn't have all the functionalities available when working on a desktop machine.  

Providing support for the merge cell, multi-cell selection  & context menu opening when working on a mobile device will be very useful for the Spreadsheet. 

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 .

Hi Team,

I would like to request the Kendo UI Spreadsheet to be able to validate by Text Length instead of using custom validation.  This would help with importing xlsx files which have text length validation.

Thank you!

Bug report

Reproduction of the problem

Dojo example.

1. Hide the second row.
2. Slowly scroll the Spreadsheet horizontally (left and right).

Current behavior

Column lines disappear and row lines appear (columns G, M, N, O). In Chrome values disappear as well, observe the value in column F. The configuration options required for reproducing the behavior are mergedCells and frozenRows.

Expected/desired behavior

No changes to the column/row lines and no disappearing values on scrolling.

Environment

• Kendo UI version: 2021.1.119
• jQuery version: x.y
• Browser: [all ]

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.

Bug report

Custom validation error can not be handled in spreadsheet

Reproduction of the problem

https://dojo.telerik.com/@zdravkov/uJuruCod
go to Data->Data Validation->Custom Formula (Ignore blank, Reject input),
open the console,
than if you enter an invalid formula (<4, >A3 or something like this) and press Apply, in the console you can see an exception

Current behavior

The exception can't be handled

Expected/desired behavior

One should be able to handle the exception

workaround - https://dojo.telerik.com/@zdravkov/adEWOlOk

Environment

• **Kendo UI version: 2021.1.119

Bug report

The Spreadsheet SLOPE and INTERCEPT functions do not calculate if arrays passed as parameters contain blank or string cells

Reproduction of the problem

1. Run this dojo

Current behavior

1. Note that cell B3, B4, and B5 return errors as a result of the calculation
2. Same data passed to the SLOPE and INTERCEPT functions in Excel returns a valid result

Expected/desired behavior

Calculation of the SLOPE and INTERCEPT functions should be consistent with Excel

Environment

• Kendo UI version: 2020.3.118
• Browser: [all]

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.
