Bug report

Reported in ticket № 1429260

Reproduction of the problem

1. Create a date in a cell in Excel, e.g. 9/9/2019 with format type as "Date";
2. Shrink the column so that the date is displayed as hash tags ####;
3. Select the cell and copy it
4. Paste it in any Kendo UI Spreadsheet cell

Current behavior

The date is pasted as string with value of hash tags.

Expected/desired behavior

The date is pasted as a date

Notes

The e.ClipboardContent.data contains the hash tag string as value, so the issue should be somewhere in the clipboard pasting logic

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.

The spreadsheet widget has no Polish localization.

Feel free to use those: https://github.com/telerik/kendo-ui-core/pull/5310

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.

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

Hello,

Is is possible to trigger validation in cells in spreadsheet control? I want to make all validation controls with a button click outside 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.

Hi there,

When a spreadsheet is linked to a datasource, if you leave a gap between previously entered rows and your new data, each cell edit creates a new item in the datasource with only the cell modified.

Here is the record after adding one cell.

and after adding another cell:

This is the state of the spreadsheet:

I managed to replicate this in dojo here: https://dojo.telerik.com/eRiHocar

Hi, I'm using the spreadsheet control and i'm having an issue with date columns.

When I enter a valid date, it works fine.

but when I enter an empty date (clicking delete on date column, or emptying out the contents)

the date gets stored as "new Date(0,0,-1)" ["Sat Dec 30 1899 00:00:00 GMT+1130 (New Zealand Daylight Time)" in my local time]

obviously, this is incorrect, and it should store the value as NULL.

it happens regardless of whether the schema/model has nullable=true.

If I manually modify the dataItem via JS, it stores it correctly as null. 

I have a dojo demo set up which replicates the issue.

https://dojo.telerik.com/oFowivUN

Steps:

1. select the ItemDate column of the first row in the spreadsheet
2. type in a valid date (e.g. 1/1/2020)
3. Click View ItemDate button (It should show the correct date)
   
4. Select the ItemDate column and empty it out (e.g. click delete)
5. Click View ItemDate button. (it should now show the incorrect date!)

Doing some investigation into the kendo code, it seems to be caused by the serialToDate method of the spreadsheet.

Thanks

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.

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
