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]

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

With Excel when you use a custom number format of #,##0.00 and you enter (10) into the cell it will be displayed as -10.  With the Spreadsheet control the same example yields (10).  How can we get the same behavior as Excel with the Spreadsheet control?

Bug report

When the Spreadsheet is bound to a DataSource upon making multiple selections in the Spreadsheet and deleting the selected ranges a JavaScript error is thrown: "Unsupported for multiple ranges." The selected cells are deleted on the UI, but the DataSource change event is not triggered.

Reproduction of the problem

1. Run the demo on DataSource binding
2. Make random multiple selections
3. Delete selection using the Delete key

Current behavior

A JavaScript error is thrown: "Unsupported for multiple ranges." The selected cells are deleted on the UI, but the DataSource change event is not triggered.

Expected/desired behavior

Upon an attempt to delete multiple selections a popup should be displayed with a warning that this operation is not supported, similar to trying Copy/Paste multiple selections.

Environment

• Kendo UI version: 2020.1.219
• Browser: [all]

This is observed also in online demos:

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

Steps:

1. Open demo
2. Edit a cell and enter text
3. Press Alt+Enter and enter more text
4. Press Alt+Enter
   
   Result: the last letter of the row is transferred to the new row

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. 

Expose API that would allow a check of whether filtering has been applied to a given range/sheet. Especially identify the case when filtering is applied but no items were filtered out.

Dear Concerned,

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

2. Move horizontal scroller to column P

3. Now select Row 1 header, then row 2 header and keep doing it

4. Please observe horizontal scroller is also moving towards left

I assume it is a bug and need a fix. Meanwhile if you can provide a workaround for the same if possible.

Note: Similar behavior can be noted for vertical scroller on column header selection

Dear Concerned,

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

2. Select column B and drag mouse towards C, both columns will be selected which is correct behavior

3. Now just scroll down 2-3 rows using vertical scroll bar

4. Repeat step 2, this time it does not select B &  C, instead it selects B,C,D,E.

5. Seems a bug, not an expected behavior.

 

Observation that might help you in fixing it:

1. if you move scroll bar in such a way so that no merged cell is visible it works well, e.g. scroll down till 20th row becomes first visible row on screen and now repeat step 2, it will work

2. if scroll position is on top then behavior is correct as well

3. Same issue exists in case of multiple row selection with merged column and scroll position.

There is an issue with the Date type fields validation in the Spreadsheet. 

Here are the reproduction steps:

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

2. Import attached xlsx file.

3. There are two date cells (B1 & B2), B2 has a data validation (Date between B1 to ToDay)

4. Try to edit the date using the calendar icon from B2. An empty calendar appears

Note: If I change data validation (remove reference of B1 and put hardcoded date) as below then it works.

Bug report

If an Excel file that contains Shapes is imported in the Spreadsheet, the imported content cannot be exported back to '.xlsx' file. Saving the imported content to Excel throws an error in the console.

Reproduction of the problem

1. Open this demo
2. Import the attached "Download Issue.xlsx" file that has one shape and one Image in the Sheet1.
3. The file import will be successfully executed. The shape from the file is not visible in the Spreadsheet(this is expected behavior as the Spreadsheet component does not support Shapes, so they are ignored during the import process)
4. Export(save) the Spreadsheet content as Excel file

Current behavior

Exporting the Spreadsheet content throws an error in the console:

Expected/desired behavior

The Spreadsheet content should be exported to Excel file that doesn't contain the shapes from the imported file

Bug report

There is no TypeScript definition for defineFunction and no custom functions can be created in TypeScript context using the approach demonstrated in this Custom functions article.

Reproduction of the problem

Try defining a new function using:
kendo.spreadsheet.defineFunction("Mask",mask).args(maskArgs)

Current behavior

The following error appears:

Propery "defineFunction" does not exist on type 'typeof spreadsheet'

Expected/desired behavior

There shouldn't be any errors

Environment

• Kendo UI version: 2019.3.1023
• jQuery version: x.y
• Browser: [all]

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.

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.

Hi,

 

I encountered a bug when using the spreadsheet control with a remote datasource which I was able to replicate using the datasource binding demo (https://demos.telerik.com/kendo-ui/spreadsheet/datasource).

When entering data on an empty cell in an empty row not adjacent to a non-empty row (e.g. a row that is two rows below the end of the data); then editing a cell in the same row, but adjacent column, this creates two items in the corresponding datasource.

Editing an empty row above this new row will modify one of the records created in this process.
