Hi Team,
I'd like to request the functionality to be able to filter null and whitespace items more easily with the built-in API for the Kendo UI Spreadsheet.
Thank you!
In Excel I can create a merged cell. For this example, I will merge A1:B1 and name the range MyCell. Next I name the single cell D5, and call it MyAnswer. I can enter the following formula into MyAnswer, =MyCell and Excel will return the result.
Using Telerik if I create the same layout I get a #Value or #Spill error because Telerik requires MyAnswer to be the same merge configuration as MyCell which creates a significant disadvantage in usability.
Can you please advise when this issue will be fixed in Telerik.
I have attached a screen recording of this not working in your Dojo named "Telerik merge cell reference not working when not same col.mov".
Thank you so much.

When there are merged cells and the SUM formula is used for the merged cells the result is wrong (it depends on the count of the merged cells)
The result in the D1 cell is 20. ( value of cell * count of cells in merged range)
The result should be 5. In the same scenario, the result in Excel will be 5.
Currently, the Spreadsheet does not appear and does not function properly when the 'k-rtl' class is applied.
Please provide Right-To-Left support for the Spreadsheet widget.
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!
The FromJson method of Telerik.Web.Spreadsheet.Workbook doesn't add images when a JSON containing an image blob is passed to it.
It would be nice if the FromJson method supports images.
Hi,
There are multiple formats for date and time in kendo and in different cultures the count increases. Is there a function in which i pass spreadsheet cell value and format and it returns that it is a date format or number format. I just want to know the type of format so i can parse the dates on my own from json on server side.
Regards,
Faraz
In my application I am using the following.
kendo.ns="kendo-";
Dojo example: https://dojo.telerik.com/@iankodj/aKIyEwUv
The spreadsheet component works well with the namespace, however any dialogs that the component opens do not function correctly.
For example, I am using Edge browser. If I copy a cell and they try and past the value via the context menu, a dialog appears telling me to use the keyboard.
The "ok" button of the dialog does not work. Looking at the html source that is added to the DOM, it appears that the button is trying to bind to the click event via a "data-bind" attribute rather than a "data-kendo-bind" attribute as specified via the namespace.
The attached file show the behavior with the Basic demo example having the kendo namespace set.
Thanks,
Darin
In Spreadsheet, the cell format is lost when you change its value.
The new value is not rounded as per the preset format.
The new value should respect the format set for the cell.
When an Excel file with 'Set precision as displayed' option enabled is imported in the Spreadsheet the calculations are not the same as in the Excel file.
Reproduction:
1. Open the Spreadsheet demo
2. Import the excel file from the zip. in the Excel file the following option is enabled - File->Options->Advanced->When Calculating this workbook-> Set precision as displayed
The value in Excel in C1 column is 399.96, while the value displayed in the Spreadsheet is 400.00
I would like to have support in Spreadsheet for Excel files with 'Set precision as displayed' option enabled.
Excel file is corrupted when it is created with the kendo.ooxml.Workbook toDataURL method, using stringified sheet data:
let dataURL = new kendo.ooxml.Workbook(JSON.stringify(data)).toDataURL();
If the data is passed to the Workbook without stringifying it, this causes a circular reference error (check the console).
let dataURL = new kendo.ooxml.Workbook(data).toDataURL();
Dojo example.
The generated Excel file is corrupted
The generated Excel file is not corrupted
It would be nice to have custom attributes for rows and cells so that I can track things behind the scenes such as row identifiers that could be used to update a corresponding rows in a the data base. This id would not be editable by the user. There are many more uses I would like this for and that is just one example.
I would rather not have to create a column in the spreadsheet just for this and then hide it. I find that very clunky.
Thanks.
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.
When values in the sheet are updated using the batch method the DataSource does not update according to changes.

1. Run the example
2. Check the console showing "no data" and an empty array.
Enable Cut/Copy cell values and can Paste it in mutiple selected values
