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

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

The select method of the range in the Spreadsheet component throws an error when we have a selected cell in the visible area of the component and try to select a range that is outside of this visible area.
The bug is replicable both when the range is passed as exact cells or row-column pair:

• sheet.range(3,2,3,3).select();
• sheet.range("C4:E6").select();

** This is a regression from the R3 2019 release

Reproduction of the problem

1. Open this Dojo
2. Scroll to row 70+ and select a random cell
3. Press the "Select range" button

Current behavior

The following error appears in the browser's console

If you scroll to the top rows of the Spreadsheet there is a visual selection of the cells that are passed in the range

Expected/desired behavior

On "Select range" click the "C4:E6" cell range should be selected and the Spreadsheet should be automatically scrolled to this selection.

Here is a working demo: https://dojo.telerik.com/uRERUxOm

Environment

• Kendo UI version: 2020.1.219
• jQuery version: x.y
• Browser: [all]

Add support for multiple ranges for the Spreadsheet's SUM function, for example: 

=SUM(E5:E6:E9:E10)

In Excel it is possible to select several rows and increase/decrease all selected rows height. In the Spreadsheet this works only for the last selected row. The following steps demonstrate the behavior:

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

2. Click on the header of row 6, hold and drag until rows 6, 7, 8, 9 , 10 are selected.

3. Click the handle below row 10's header and drag to increase the height of the rows. The Spreadsheet increases only the last row's height.

Bug report

Reproduction of the problem

Reproducible in this demo: https://demos.telerik.com/kendo-ui/spreadsheet/datasource

1. Scroll down to row 78
2. Focus A78 and drag to E78. Copy the data
3. Paste over the empty 79 row's first cell
4. Press Ctrl + Z to undo the changes.
5. Open the browser's dev tools network tab and press the "Save" button above the Spreadsheet.

Current behavior

The data cleared by the "undo" shortcut is saved and sent to the server

A different behavior is exhibited if the data is pasted over the row header instead of the row's first cell. Follow the same steps, but on step 3. instead of pasting over the first cell, paste the data over the row 79 header. After undo and then clicking "Save", the fields have null values.

Expected/desired behavior

No data is sent with the request

Environment

• Kendo UI version: 2020.2.617
• jQuery version: x.y
• Browser: [all]

Bug report

When using a custom cell editor in the Spreadsheet along with keyboard navigation value selection is not limited to the cell with the custom cell editor

Reproduction of the problem

1. Run the Custom Editors Demo
2. Click on cell B2 and open the list popup with available values for selection
3. Press the right arrow key on the keyboard
4. Select a value from the list
5. The selected value will be applied to cell C2

Current behavior

The selected value is applied to cell other then the one using the custom cell editor

Expected/desired behavior

The selected value should be applied only to the cell with the custom cell editor

Environment

• Kendo UI version: 2020.2.617
• Browser: [all]

Bug report

Memory usage is increased if the DevTools is open. Navigation between sheets is also slower.

Reproduction of the problem

1. Open our Spreadsheet demo in Chrome.
2. Import the attached Spreadsheet.
3. Open the Task Manager to check Chrome memory usage, and switch sheets to see the navigation speed.
4. Open DevTools and check memory usage again. Note that switching sheets is also significantly slower.

Current behavior

Memory usage increased and slower sheet change.

Expected/desired behavior

Memory usage should not be increased and sheet navigation should not be slow.

Environment

Hello,

I have some problems with setting up correct Cell Validation for my use-case. I want to create a list validation which is going to have a numeric options instead of typical string values.

So in order to achieve that I created a following cell validation:

{
    dataType: "list",
    showButton: true,
    comparerType: "list",
    from: '{1,2,3,4,5}',
    allowNulls: true,
    type: "reject"
}

Everything works fine in the widget, but the problems starts when I want to Export the following spreadsheet to Excel format. I'm getting the following message when trying to open such file:

In the past I had a similar problem with the list validation (but for string values) (https://www.telerik.com/account/support-tickets/view-ticket/1381434)

There you suggested to create a validation using different format for "from" property. So I decided to change it from:

from: '{1,2,3,4,5}',

to

from: '"1,2,3,4,5"',

After that I can freely export the spreadsheet without any problems, but then my list is inserting string values instead of numeric ones, therefore this solution is not suitable for my use-case.


And my question is: Is there a possibility to create a Cell validation where I can put numeric values as a possible options without breaking the export process? 

Here's a example spreadsheet, which I used to reproduce this behavior: https://dojo.telerik.com/IfuMIbic

Best regards,

Hi Team,

I would like to request the ability to set an autoFit for the rows/columns(specific or all).  This would not just related to wrapping. 

For example, in the following Progress Kendo UI Dojo, the user can create 3 lines by button press.  But if the user replaces the contents with 1 line of text, it will keep the height of when the 3 lines were in cell.  

I know I could use the rowHeight method, but it would be great if there was a way for it to resize automatically.

Thank you for your consideration.

Hi Team,

I'd like to request a built in method for finding the intersection of ranges for the Kendo UI Spreadsheet.  

Thank you

Bug report

Related To: #5500

When there are merged cells and the SUM formula is used for the merged cells the result is wrong (it depends on the count of the merged cells)

Reproduction of the problem

1. Open the Dojo
2. Enter for example 5 in the merged cells (A1:B2)

Current behavior

The result in the D1 cell is 20. ( value of cell * count of cells in merged range)

Expected/desired behavior

The result should be 5. In the same scenario, the result in Excel will be 5.

Environment

• Kendo UI version: 2020.3.1118
• Browser: [all ]

Bug report

Reproduction of the problem

Reproducible in the demos. The attached video demonstrates the issue.
Recording49.zip

1. Reduce to minimum the width of several adjacent columns
2. Increase the width of one of them

Current behavior

As shown in the video, the F column completely disappears. The column letter remains visible within the next column (G). F column's resize handle remains hidden, and it cannot be made visible.

Expected/desired behavior

There should be a minimum column width that should be respected on resizing. Its value should always allow the column to be resized. No column overlapping should occur.

Environment

• Kendo UI version: 2020.3.1118
• jQuery version: x.y
• Browser: [Chrome 87 ]

Can you add feature or set option to allow text to run into adjacent cells to right? 

(example in ticket 1500102)

Currently, when an invalid validation formula is used, the Spreadsheet throws a js exception.

For example: https://dojo.telerik.com/AWEyIHoW

Open the Data/Data Validation dialogue on cell A3 and modify the Value of the Formula into an Invalid formula (e.g. : “>3”)

A parse error is thrown.

It would be a nice improvement, if instead of throwing a js exception, the user is notified about the invalid formula through a dialog showing a relevant message.

Currently, Kendo UI for jQuery Spreadsheet does not support many events such as style change, merge, unmerge, image insert, font change, alignment change, decimal change, filters and more.

But these events need to be captured in many cases.

Please support events for all the actions.
