Bug report

cell connection in Spreadsheet is not working when the sheet contains 1.0 in the name

Reproduction of the problem

download the file from ticket - 1500102
open our demo - https://demos.telerik.com/kendo-ui/spreadsheet/index
open the file from the ticket in the Kendo Spreadsheet

Current behavior

cell F17 is not connected with cell B12 from the second sheet

Expected/desired behavior

cell F17 is connected with cell B12 from the second sheet

note: if the name of the sheet is changed to something different than 1.00 for example 'A' the cells are connected

Environment

• **Kendo UI version:2020.3.1118

Can you add feature or set option to allow text to run into adjacent cells to right? 

(example in ticket 1500102)

I see some potential for improvements here, I see how the Spreadsheet entirely depends on the JSON structure. It doesn't have to be like this as the setDataSource() method shows clearly that the columns could be further configured: 

https://www.telerik.com/forums/datasource---specify-columns#msCK2ytWcESxeUMs-6a3uQ

Therefore, the Sheet columns could be configured upon the widget initialization. Such configuration options could be represented in the following manner for the HTML helper version of the widget:

.Columns<Kendo.Mvc.Examples.Models.SpreadsheetProductViewModel>(columns =>
{
    columns.Add(c => c.ProductId).Name("Product ID").Width(100);
    columns.Add(c => c.ProductName).Name("Name").Width(415);
})

Bug report

When importing from Excel in Spreadsheet if a date is entered, but the date format is not set explicitly, the imported date always has the following format: "mm-dd-yy". The issue is observed even if a culture is set.

Reproduction of the problem

1. Open the Dojo example
2. Import the following file
   DateFormat.xlsx

Current behavior

The value in Excel is "15.6.2020" , but the imported date in the Spreadsheet is "05-15-20" screencast

Expected/desired behavior

The format of the dates should be the same as in the imported file.

Environment

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.

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,

When multiple cells are merged in the Spreadsheet the DatePicker is not always rendered at the correct position.

Reproduction of the problem

1. Open the Demo
2. Merge the cells vertically for rows 6-20.
3. Reduce the browser size to set the scrollbars, so the Spreadsheet scrollbar to not be at its top position.
4. Open the DatePicker.

Current behavior

The DatePicker is not always entirely visible (screencast)

Expected/desired behavior

DatePicker should be visible

Hi Team,

I'd like to request a built in method for finding the intersection of ranges for the Kendo UI Spreadsheet.  

Thank you

Hi Team,

I would like to request the ability to set an autoFit for the rows/columns(specific or all).  This would not just related to wrapping. 

For example, in the following Progress Kendo UI Dojo, the user can create 3 lines by button press.  But if the user replaces the contents with 1 line of text, it will keep the height of when the 3 lines were in cell.  

I know I could use the rowHeight method, but it would be great if there was a way for it to resize automatically.

Thank you for your consideration.

Dear Concerned,

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

2. Select Column B11, click wrap text from Home toolbar.

3. Start typing in B11 & see cell editor keeps growing and goes beyond screen.

4. This is not user friendly, it should be same as Excel

5. Any alternative or quick fix would be appreciable

Hi Team,

I'd like to request a way to manipulate a large amount of cell groups in the Kendo UI Spreadsheet without decreasing performance.  For example, I'd like to be able to merge/unmerge and change font size to multiple specific cell groups.  I understand changing multiple DOM elements at the same time can cause sluggishness, but maybe there's a way to reduce the time. Currently, it's taking a long time to completely load.  

Thank you for investigating.

Bug report

There is no TypeScript definition for defineFunction and no custom functions can be created in TypeScript context using the approach demonstrated in this Custom functions article.

Reproduction of the problem

Try defining a new function using:
kendo.spreadsheet.defineFunction("Mask",mask).args(maskArgs)

Current behavior

The following error appears:

Propery "defineFunction" does not exist on type 'typeof spreadsheet'

Expected/desired behavior

There shouldn't be any errors

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.

In the Spreadsheet control for jQuery it is possible to set cells as read-only through the use of the Enable property.

However, on calling saveAsExcel() these cells are editable. This means as a developer it is then necessary to create both the spreadsheet JSON (for Kendo Spreadsheet) as well as another spreadsheet class to export to Excel.

Could you please map the Cell.Enable property to the setting of Excel cells as disabled/read-only. Thanks 👍

Bug report

Memory usage is increased if the DevTools is open. Navigation between sheets is also slower.

Reproduction of the problem

1. Open our Spreadsheet demo in Chrome.
2. Import the attached Spreadsheet.
3. Open the Task Manager to check Chrome memory usage, and switch sheets to see the navigation speed.
4. Open DevTools and check memory usage again. Note that switching sheets is also significantly slower.

Current behavior

Memory usage increased and slower sheet change.

Expected/desired behavior

Memory usage should not be increased and sheet navigation should not be slow.
