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 ]

When using the bottom right corner of a cell to batch copy values across a range by dragging the corner, an error popup appears if a disabled cell is found inside the range that was dragged into.  It is possible to reproduce this with this demo:

https://demos.telerik.com/kendo-ui/spreadsheet/disabled-cells

1.  Set the quantity column to disabled.

2. Select B3.

3.  Drag the bottom right corner of B3 to D3.

4.  See error: "Destination range contains disabled cells."

There should be an option to allow that to copy into any enabled cells in that range and ignore the disabled ones.

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

Support scenarios where users can use the spreadsheet component to design templates with disabled cells.

I appreciate that this can be customized (as almost anything) but note this is the only cell property that is not configurable via the toolbar.

Bug report

Reproduction of the problem

Use the Events demo to reproduce, since the events are logged in the console: https://demos.telerik.com/kendo-ui/spreadsheet/events

1. Add a new sheet
2. Drag left the newly added sheet, to make it first
3. Click "Invoice", hold down the mouse button and drag the Invoice sheet back to first place

Current behavior

The Invoice sheet is selected but the selectSheet event does not fire.

Expected/desired behavior

The selectSheet event fires

Environment

• Kendo UI version: 2020.2.617
• jQuery version: x.y
• Browser: [all]

Bug report

Reproduction of the problem

Dojo example.

1. Change a value in the second column, for example change 8 to 7.
2. Open the column filter menu. The filter menu properly shows the current values (5 and 7).
3. Close the filter menu and change the cell value again.
4. Open the column filter menu.

Current behavior

After the initial value change the filter menu no longer shows the current value of the modified cell.

Expected/desired behavior

The filter menu should always show the current values of the cells.

Environment

• Kendo UI version: 2020.3.1118
• jQuery version: x.y
• Browser: [all]

Bug report

Values that are copied from Spreadsheet are duplicated when pasted in Excel if before that the copied cells have been cut and pasted inside the Spreadsheet.

Reproduction of the problem

1. Open this Dojo project
2. Cut B3:C3
3. Paste the copied content to A1:B1
4. Copy A1:B2
5. Paste to Excel

Current behavior

In Excel, the first row is duplicated and the pasted content contains 3 rows, while 2 rows are copied

Expected/desired behavior

The pasted in Excel content should contain 2 rows instead of 3

Environment

• Kendo UI version: 2020.3.1021
• jQuery version: x.y
• Browser: [all]

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.

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

• Kendo UI version: 2020.3.1118
• Browser: [all ]

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,
