The filtering on the spreadsheet component is great!!

There is however one behaviour that causes confusion for end users, and that is filtering when merged cells  are present in the selection.  
An example is available in the following dojo:
https://dojo.telerik.com/UzUMUDos

Open the dojo and filter column A on a1 and you will only see only b1 in column B, but the b1a will not be shown.

To be clear - This is also how Excel behaves...  (which is of course your prime aim so its not a bug as such)... 
Interestingly google sheets stops you putting filter on merged cells / stops you merging on filtered column.

The Excel behavior is discussed in the following threads:
https://stackoverflow.com/questions/49816515/excel-filtering-for-merged-cells
https://www.officetooltips.com/excel_2013/tips/workaround_for_sorting_and_filtering_of_merged_cells.html

Is it possible to implement something, so the end user experience would be improved? Maybe when merged cells are present :
a) if they click filter, this is detect and user is warned of this behaviour
b) if they click filter, the sheet is changed into an unmerged version (which repeats data in merged cells) as in the excel examples above.

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.

Bug report

Dates and times entered (or pasted) in the spreadsheet are incorrectly parsed and do not respect the specified format. For example, dd.MM.yyyy HH:mm becomes MM.dd.yyyy HH:mm. The issue is replicated even if a culture is set.

Reproduction of the problem

1. Open the Dojo
2. Add the following date in Excel file and paste it in the Spreadsheet - 10.01.2022 09:00

Current behavior

The Spreadsheet does not parse the dates correctly.
10.01.2022 09:00 (january 10th) becomes 01.10.2022 09:00 (october 1st)
13.01.2022 09:00 is not affected by this issue.
10.01.2022 (january 10th, without time) is not affected by this issue.

Expected/desired behavior

Spreadsheet should parse the dates as they are. Copy dates such as 10.01.2022 09:00 should remain 10.01.2022 09:00 without switching the month and date values

Currently, when a custom button is configured in the Spreadsheet toolbar a separator is added before the button. I would like to have an option to configure whether such a separator is to be rendered or not.

I would like to avoid adding custom styles for hiding unneeded separators, which is needed with the current implementation (Dojo). 

Bug report

When a border is applied and there are frozen rows/columns the border appears splitted with a white lin in the middle.

Reproduction of the problem

1. Open the Dojo example.

Current behavior

The bottom border and the right border are split with a white line in the middle.

Expected/desired behavior

The border should appear entirely filled with the selected color.

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

When defaultCellStyle is used the configured font is applied to the cells in the Spreadsheet. However, the font is not applied when adding new rows.

Reproduction of the problem

1. Open the Dojo.
2. Enter some text in the cells
3. Insert a new row
4. Enter text in the newly inserted row.

Current behavior

The configured font in the defaultCellStyle is not taken into account. The font in the newly inserted row is Arial 12, while in the example it should be 'Courier New' 18.

Expected/desired behavior

The font configured by using the defaultCellStyle option should be applied to all cells in the Spreadsheet, even if inserted after initialization.

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.

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.

Hello

When we have filtered rows in a spreadsheet (some rows are hidden) and we copy a single cell and paste into a range containing the hidden rows....

The spreadsheet copies the value into all cells in the range including those that are hidden.  This is not the same functionality as Excel.

That said, is the any way to skip hidden cells in the paste range?

Is there a way to override the Kendo past function to do this?  Can you provide an example?

Thank you

Jeffrey Suffet

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

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.
