Hi Kendo Team,

The exported excel file from spreadsheet can not be opened in Microsoft excel when the spreadsheet has both a comment and a image.

You can reproduce the issue at your demo site https://demos.telerik.com/kendo-ui/spreadsheet/index

First add a comment for cell D3, then add a image, then export as xlsx.

Try open the export excel file, and you will see the error popup says "we found a problem with some content in workbook.xlsx ......"

It works when exporting comment and image separately.

Hi,

I encountered a bug when using the spreadsheet control with a remote datasource which I was able to replicate using the datasource binding demo (https://demos.telerik.com/kendo-ui/spreadsheet/datasource).

When entering data on an empty cell in an empty row not adjacent to a non-empty row (e.g. a row that is two rows below the end of the data); then editing a cell in the same row, but adjacent column, this creates two items in the corresponding datasource.

Editing an empty row above this new row will modify one of the records created in this process.

Bug report

The select method of the range in the Spreadsheet component throws an error when we have a selected cell in the visible area of the component and try to select a range that is outside of this visible area.
The bug is replicable both when the range is passed as exact cells or row-column pair:

• sheet.range(3,2,3,3).select();
• sheet.range("C4:E6").select();

** This is a regression from the R3 2019 release

Reproduction of the problem

1. Open this Dojo
2. Scroll to row 70+ and select a random cell
3. Press the "Select range" button

Current behavior

The following error appears in the browser's console

If you scroll to the top rows of the Spreadsheet there is a visual selection of the cells that are passed in the range

Expected/desired behavior

On "Select range" click the "C4:E6" cell range should be selected and the Spreadsheet should be automatically scrolled to this selection.

Here is a working demo: https://dojo.telerik.com/uRERUxOm

Bug report

2. Click on cell B2 and open the list popup with available values for selection
3. Press the right arrow key on the keyboard
4. Select a value from the list
5. The selected value will be applied to cell C2

Current behavior

Hello,

I have some problems with setting up correct Cell Validation for my use-case. I want to create a list validation which is going to have a numeric options instead of typical string values.

So in order to achieve that I created a following cell validation:

{
    dataType: "list",
    showButton: true,
    comparerType: "list",
    from: '{1,2,3,4,5}',
    allowNulls: true,
    type: "reject"
}

Everything works fine in the widget, but the problems starts when I want to Export the following spreadsheet to Excel format. I'm getting the following message when trying to open such file:

In the past I had a similar problem with the list validation (but for string values) (https://www.telerik.com/account/support-tickets/view-ticket/1381434)

There you suggested to create a validation using different format for "from" property. So I decided to change it from:

from: '{1,2,3,4,5}',

to

from: '"1,2,3,4,5"',

After that I can freely export the spreadsheet without any problems, but then my list is inserting string values instead of numeric ones, therefore this solution is not suitable for my use-case.


And my question is: Is there a possibility to create a Cell validation where I can put numeric values as a possible options without breaking the export process? 

Here's a example spreadsheet, which I used to reproduce this behavior: https://dojo.telerik.com/IfuMIbic

Best regards,
