For the time being the Spreadsheet parser is unable to read files which tags are not in the default namespace. Try to open the attached file in this demo project: https://demos.telerik.com/kendo-ui/spreadsheet/index. 

You won't be able to load the file. If you open the file in Excel, save the file ("Ctrl+S") and try to load it in the Spreadsheet again, there will be no issues with it. The difference in file's structure before and after being saved in Excel could be seen in the attached screenshot.

The code in red is the structure of the file before saving it and the one in green is after the "save" operation. The difference between the files is that the structure of the one saved in Excel inserts the tags in the default namespace while the original document uses the "x:" namespace. 

It will be very useful if we can load files with defined namespaces in their structure. 

Bug report

The Spreadsheet doesn't' load correctly Excel files which definition of the tag is a single cell, instead of a cell range.

Test files: test-2.zip

Reproduction of the problem

1. Download the test-2.zip file and load the "test.xlsx" file in the Spreadsheet here.
2. The file has data in the “AZ” and “BA” columns and once it is imported in the Spreadsheet the data from the “BA” column is imported in the “AX” column and the values in the AZ column are missing.

• If the above file is saved in Excel it is correctly loading in the Spreadsheet. In the attached archive there is the “test-copy.xlsx” file which is the saved and correctly working one. Below is the structure of the two files. The one in red is from the "test.xlsx" file and the code in green is from the "test-copy.xlsx" file.

Current behavior

The The "test.xlsx" file is not loading correctly in the Spreadsheet and loses data

Expected/desired behavior

The "test.xlsx" file should load correctly in the Spreadsheet without losing data

Environment

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

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.

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.

 

Bug report

The AND formula, when used as part of an array formula, does not evaluate the whole array.

{=AND(A1:D1="")} would return TRUE if a value is entered in the range B1:D1 and FALSE only if value is entered in A1
=IF(AND(A1="",B1="",C1="",D1=""),TRUE,FALSE) would return FALSE if value is entered in any cell in range A1:D1

Reproduction of the problem

1. Run this dojo
2. Select cell E1, press F2 to edit formula and press Ctrl+Shift+Enter to enter as an array formula

Current behavior

1. Enter a value in cell B1 - Array formula evaluates as TRUE, Non-array formula as FALSE
2. Only if a value is entered in A1 the Array formula will evaluate as FALSE

Expected/desired behavior

Array formula should be evaluated correctly and return FALSE when a value is entered in any cell in range A1:D1.

Environment

Since the Spreadsheet does not support macros, implement error handling in the widget that notifies the user if they attempt to load a file that contains a macro. For more details see: Ticket ID: 1486172

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.

Currently, in Kendo Spreadsheet multiple rows/columns can not be selected by using Shift + click. For example, in Excel, if the user clicks on the first column header, then press 'Shift' key and click on the fifth column header all five columns will be selected. The same is valid for row selection.

I would like to have the possibility for multiple rows/columns selection by using the Shift key +click In Kendo UI for jQuery Spreadsheet.

 

Hi Team,

I would like to request the Kendo UI Grid to improve performance when evaluating multiple formulas.  At this point, if I use a formula on multiple rows(over 1500 rows), the page slows and eventually crashes.  This happens when I use the fromFile method too.  

Thank you for the consideration!

 

Hi Support Team,

Would like to have a feature below:

• To allow right-click along row and column headings to insert rows and columns.

Bug report

YEAR, MONTH and DATE functions do not return the same value on a black cell as in MS Excel

Reproduction of the problem

Apply the Year, Month or Date functions on any blank cell, it returns #VALUE!, where as Excel returns the respective value. 

Environment
Kendo UI version: [all]
Browser: [all]

Hi Team,

I would like to request the functionality to be able support multiple languages for the Excel file.  It would be great if there was a way to make the file content automatically change to a specific language. 

For example, if we could use a collection of <English key, French strings> of a selected language e.g. French, and all Excel text strings matching with the English key would convert to the French text.

Thank you!

Hi again :)

I see that in the configuration I can specify the max number of rows/column. However, I can do it per component basis, and I would like to have that on a per-sheet basis. Any way I can implement this?

Thanks!

I am working on a project where i am using KendoUI components. I have to show a financial sheet. All formulas are working fine like SUM,INDIRECT etc. but IRR not working as expected.

Tested IRR formula outside my project and the same happened.

Add ability to add group multiple columns and add a group header for those columns.

Expose a property on the range object of the spreadsheet component which shows whether a range is currently hidden or shown

1. Formula selection dragging

2. Formula selection resize

Details: While using cell references in formulas in a cell, user should be able to drag and resize the referenced cell selection.

Refer the video present here for details.

WorksheetPageSetup would be a dialog in the kendo ui spreadsheet and persist when the work book is downloaded as Excel or pdf. 
The setup values would also be used to prepopulate the settings in the download dialog.

WorksheetPageSetup would be maintained when a server-side generated Telerik.Windows.Documents.Spreadsheet.Model.Workbook is converted to a Telerik.Web.Spreadsheet.Workbook by method FromDocument().

Page setup maintains settings for printing: orientation, scaling, margins, paper size, grid lines, column headings etc...

The spreadsheet widget should be able to take an imported .xlsx file, such as a preconstructed template, and update bound database tables if the fields match.

When we use custom validation for a cell using below method
kendo.spreadsheet.defineFunction("CUSTOM_VALIDATION", function(num){});
its triggered for each cell. Let say i have applied this validation method for 100 cells. If i changed any one cell then this method got invoked 100 times. Instead it should execute single time i.e, for that changed cell only. We cant keep 100 different methods for 100 cells. This will impact more on performance. Please look it on this and fix accordingly. 
This feature will be helpful for complex usage.
