Dear Concerned,

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

2. Import attached Dummy.xlsx file

3. No data loaded

4. please check

 

 

On Internet Explorer-11, UI is getting blocked while performing comparatively fast data entries, it is not only too slow but values are getting truncated as well.

 

1. Open https://demos.telerik.com/kendo-ui/spreadsheet/index in IE 11

2. Start editing cells C3 to C12 and enter value 1234 in each cell as fast as possible

3. 1234 enter, 1234 enter , 1234 enter and so on without waiting for UI rendering completion as UI freezes for few seconds, and then all cells get updated in one go

4. below is the result, few cells are having wrong values 

5. Its very serious issue

Note: Excel 365, Excel and GoogleSheet works fine in such cases

Currently sorting is not supported for a Spreadsheet which has its Sheet bound to a Kendo DataSource.

Needs:

Load big excel files stored on the server

Possible implementation:

Load on demand data:

First load the file structure (sheets name, column names and number of rows)

Then load data when sheet is selected or scrolled

Need a default cell format, in addition to rowHeight and columnWidth including:
- font size,
- font-family,
- font weight
- (see other toolbar options)

Default cell format would set the default values for all cells and toolbar options.

Bug report

Reproduction of the problem

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

Current behavior

import a file from ticket - 1447268

A warning is displayed

Expected/desired behavior

No warning is displayed

Environment

• **Kendo UI version: 2019.3.1023

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.

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.

Structured references in MS Excel: 

• https://support.microsoft.com/en-us/office/using-structured-references-with-excel-tables-f5ed2452-2337-4f71-bed3-c8ae6d2b276e   

Example formulas that should work (Table1 is a named reference of a table):

1. =Table1[Column2] is not working in kendo 

2. =Table1[#Header]  -- Header, Data, All and all other specifiers.

 

3. =[@ColX] also not working .

Different scroll position should be persisted for each sheet.

Bug report

Reproduction of the problem

Reproducible in the demos.

1. Use the HYPERLINK function in a cell:

=HYPERLINK("https://google.com")

Current behavior

The link does not work. It does if you specify a "friendly name":
=HYPERLINK("https://google.com", "google")

Expected/desired behavior

The link works with and without a "friendly name" specified, as in Excel.

Environment

• Kendo UI version: 2019.2.619
• jQuery version: x.y
• Browser: [all]

Dear Concerned,

 

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

2. Open Attached Test.xlsx file

3. Check the value of A2, it is different than Excel

Note: Cell format of A2 is set as below, if I select only $ format then it is working.

Dear Concerned,

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

2. Start editing cells D3 to D11 as fast as possible (like type 45 enter, 45 enter, 45 enter and so on) (refer attached videos)

3. UI freezes for few seconds, and then all cells get updated in one go

4. But Excel 365, Excel and GoogleSheet work fine in such cases

5. Please make similar UI behavior as in Excel.

 

Check attached Excel Data Entry & Kendo Data Entry video recordings

Dear Concerned,

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

2. Upload the attached sample.xlsx file.

3. Cell B1 getting value from cell A1 using formula "=TEXT(A1, "$#,###")"

4. Delete(Blank) the value of cell A1, see error #VALUE! in cell B1.

5. The same is working fine in Excel.

6. Please suggest any workaround or quick fix.

 

 

Check attached Sample.xlsx file in Sample.zip folder

It should be possible to define cell types (or types that are valid for the entire column) like:
- Booleans (which will result in showing check boxes inside the cells)

Currently, when the "Custom format" button in the Spreadsheet is clicked, the available predefined formats that can be applied to a cell appear as demonstrated in the below screenshot. These predefined options don't change if you set a specific Kendo UI culture. 

It will be a very useful feature to be able to change the predefined custom formats. Also, it will be nice if the custom formats in the Spreadsheet can be set based on the selected Kendo UI culture. 

It would be nice to have text orientation support (at least vertical) like in MS Office.

Currently only the global culture is used to parse dates. This behavior differs from Excel as I can enter 1/1/19 to parse to 1/1/2019.

I would like the widget to format using the chosen date culture (mm/dd/yyyy), but parse in an optional way, such as mm/dd/yy.

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.
