Hi Kendo Team,

The exported excel file from spreadsheet can not be opened in Microsoft excel when the spreadsheet has both a comment and a image.

You can reproduce the issue at your demo site https://demos.telerik.com/kendo-ui/spreadsheet/index

First add a comment for cell D3, then add a image, then export as xlsx.

Try open the export excel file, and you will see the error popup says "we found a problem with some content in workbook.xlsx ......"

It works when exporting comment and image separately.

Bug report
Spreadsheet SUMIF function returns #NA when Excel returns the correct result. The issue is observed when the criteria range and sum range have different sizes.

Reproduction of the problem
Run the Spreadsheet demo page
Open the attached file
Formula in cell B3 returns #NA!

Current behavior
The formula in cell B3 returns #NA!

Expected/desired behavior
The formula in cell B3 should return the correct value

Environment
Kendo UI version: 2019.3.1023
Browser: [all]

Dear Concerned,

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

2. Import attached Book21.xlsx file

3. I have first row as frozen pane and columns C, D are hidden

4. Select columns B to E using mouse drag & then right click on selected column , it does not show Unhide option, because on right click it keeps the selection only on column E

It does not work if we keep Freeze Panes.

Reproduction of the problem

Environment

• **Kendo UI version: 2019.3.1023

Please support Excel formulas copy and paste to Kendo Spreadsheet.

Now is the copy only the text, not formulas.

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

1. Enter some text in a cell.

2. Increase the cell font size to 48.

3. Reduce the cell font size to 8.

4. Double click the row resize handler: the row height is not adjusted to correspond to font size 8.

The same behavior can be observed when opening an existing .xlsx file that has some text and font size set and following steps 3-4.

Different scroll position should be persisted for each sheet.

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

2. Put some text in B2 so that it does not fit in the cell width.

3. Press Wrap Text button 

4. Press Wrap Text again

5.  The row height is not adjusted back to the original height (Excel does it)

Dear Concerned,

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

2. Import attached Book1.xlsx. Observe Cell F4 of Sheet1 has a font size of 72.

3. Change it to 8, row height does not change automatically

4. It should be same as Excel behavior


Please provide a fix or any workaround in the meanwhile.

Ability to hide a sheet in kendo spreadsheet

Dear Concerned,

I have observed that Conditional Formatting in Spreadhseet is not supported. Please add support for the same as it is very important feature of XLSX.  during financial calculation this feature plays an important role. Here is the issue that needs a fix.

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

2. Check attached file CellColorFormula.xlsx, conditional formatting set for B2, C2, D2

3. Import attached file CellColorFormula.xlsx

4. Check Cells B2, C2, D2 and try to change values for A2, C2, D2

5. None of the conditional formatting is working

 

Dear Concerned,

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

2. Copy from F3:F15

3. Paste as value (ctrl+shift+v) in H3

4. See it pasted only non-empty cells

Empty cells values should be pasted as well as Excel does.

 

Dear Concerned,

It would be very useful if Kendo can provide two more functions like fromJSON & toJSON in a Spreadsheet as mentioned below

fromStream() - to load an excel file form an Excel stream string so that the developer does not need to convert it to blob etc.

toStream() - to return excel stream string, it would good if it is possible to get stream without blocking UI operation. As of now, we first call toJSON & then call kendo.ooxml.Workbook(jsonSpreadsheetData).toDataURL(); to get excel stream and it is time consuming operation.

Use case: keeping excel file/stream on the server and fetching it using API on UI and then using fromStream to load & render it. And toStream is the same as toJSON to save modified stream back to the server since stream size is very low as compared to json.

Please see if it is feasible to provide these features.

It would be useful if it is possible to filter between a range of values, like in Excel. For example filter for values that are between 3 and 6.

Bug report

The wrap text tool hides some of the cell's text if it is too long.

Reproduction of the problem

Go to this Dojo. Select cell A1 and toggle the wrap text tool. The beginning of the text is not displayed.

Current behavior

Part of the cell's content is hidden.

Expected/desired behavior

All the text should be visible.

I would like to be able to generate PDF from spreadsheet using HTML template (like http://dojo.telerik.com/Ovegu), so i could specify headers and footers for all PDFs that are created by the user.

Currently, when trying to load a corrupt XLSX file, the Spreadsheet will freeze and no message will be returned to the user. Improve the widget to unfreeze the view and notify the user about the problem.

Add option for manual calculation of formulas, as available in Excel.

It would be a great feature to have to save time for inputting values without updating other dependent cells and once data entry is done user could press "Calculate Now" and all of the cells updated in one go, same as we do have this feature in MS Excel 365.

I am using kendo spreadsheet binding to a datasource... very similar to the demo: https://demos.telerik.com/kendo-ui/spreadsheet/datasource

Is there a way to add a two row header while binding to a data source?  For example, my first row would be a merged cell spanning all columns and would contain some text.  I can see how to do two row headers and to merge cells.. but it doesn't work when the spreadsheet is bound to a datasource as it starts the data in row 2.... where I want row 2 to be my actual field name headers.  I don't see any options to fix that.

If there is no way to do that... is there a way to alter my header style?  For example, I want a column header to be

MY FIELD NAME HERE
additional text (smaller font and color)

I know in kendo grid there is headerTemplate... but this doesn't seem to be available in kendo spreadsheet.

Thank you.

 

Excel supports deselecting cells from selected ranges, e.g. selecting a range from cell A1 to A10 results in a range A1:A10. Then deselecting cell A5 from that range produces two new ranges - A1:A4 and A6:A10.

Now a more complex example - selecting multiple ranges with intersecting cells - A1:B10, A5:D10, A9:C14 and A9:G9.


Deselecting cell B9 in Excel produces a new range with cell A9 only and then a range C9:G9. And B9 should be excluded from the other 3 ranges.

Currently the Spreadsheet widget does not know how to do this. There is no logic to decide what new ranges should be created on such operation. What it currently knows is creating new ranges and these ranges may overlap. Thus clicking on cell B9 creates a new range with cell B9, instead of deselecting B9 from the already selected ranges.
