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 👍

When I use this formula 

=HYPERLINK("mailto:"&B4&"?subject=“& B5 & “&body=“ & B6,", "test")

in the excel, I am able to click on the link which opens up my mail client with compose new email window and also populates To, Subject and Body of the email from cells B4, B5, B6 respectively.

But currently, HYPERLINK formula does not support "mailto:" functionality in Kendo UI spreadsheet. I would love to see this with kendo UI spreadsheet. 

For more details you can see the discussion on the forums here. 

Need:

Extract only the values for all Spreadsheet cells. These extracted values can be sent back to server (with minimum size) as server only needs data on each sheet. On other information required like references, formulas, images, colors etc.

Possible Approach:

On click of save or a separate button, which will generate a low size data file (having sheet name, cell index and value), which we can send to server.

It will save network traffic and also no complex parsing needed at server side to fetch data.

Dear Concerned,

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

2. select row header of row 10, go to Insert tab

3. click insert row below, it inserts row successfully after row 10, it adjust formulas of row 12, and other rows there after which is good.

4. But issue is - it neither keep format of row 10 in new row & nor it add formulas to various columns in new row(e.g. F11, E11)

Please suggest how can we achieve it, it is very common and useful feature which excel have. if you do not have any ready solution then please suggest workaround for the same as it is urgent for my client.

Additional functionality for:
-- Conditional Formatting -- coloring of cells, for example based upon a value and then be able to import from excel, and export back out.
-- Data Validation (dropdowns).  Also be able to import and export back out.

Hi,

I want to highlight spreadsheet on cell hover. But I just want to highlight row and column until cell. Is there any way to do this ? 

In example, When my mouse on cell E11.

Best Regards,

Kaan

In Excel it is possible to select several rows and increase/decrease all selected rows height. In the Spreadsheet this works only for the last selected row. The following steps demonstrate the behavior:

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

2. Click on the header of row 6, hold and drag until rows 6, 7, 8, 9 , 10 are selected.

3. Click the handle below row 10's header and drag to increase the height of the rows. The Spreadsheet increases only the last row's height.

Currently, the sheets in the Spreadsheet component can be reordered. It will be a very useful feature if we can configure the component in a way this reordering can be disabled.

Thus the users won't be able to move the sheets' tabs.

It would be great if you would add accessabbility to the spreadsheet as it seems to be the last control without this feature.

Currently the focus gets trapped inside its grid and the user cannot leave the spreadsheet with the TAB key. At least this should be avoided. It would be also better if only the first cell would be focusable and you then could navigate with the arrow keys, as with thousands of cells it is not very comfortable to use the TAB key.

Add support for multiple ranges for the Spreadsheet's SUM function, for example: 

=SUM(E5:E6:E9:E10)

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

Environment

• Kendo UI version: 2020.1.219
• jQuery version: x.y
• Browser: [all]

Right now, a List based validation is strict on case, it'd be nice to have a toggle for when it is appropriate.

Add menu item that allows end users to style background and text color based on rules (if cell value > 0 then green)

Add a watermark in each worksheet.

I know it seems like a small thing, but I work with complex spreadsheets, and supporting coloured sheet tabs would really help 
Love this control.

Hi Progress - just some quick feedback: 1. Telerik Control Panel updates - it feels like a lot of the time, when the TCP needs updating the user has to manually uninstall the old version and the install the new one using the .exe installer. If the TCP could automatically handle this process, that would be appreciated. 2. The various Telerik Spread Processing libraries (and other document processing libraries) can only be installed as an included component of the Telerik "UI for X" library installations. It would be great if there was an option in the TCP to do a standalone installation of just the Spread Processing libraries. Thanks and kind regards, - Lawrence
