2. Select the new sheet ("Sheet1") and scroll the horizontally to column U. Add a value to the U1 cell.
3. Select the first sheet ("Food Order").
4. Select A17 and enter the following value: =SUM(C5,
5. Select "Sheet1" and try to navigate to U1 either through the keyboard or through scrolling the sheet.

Current behavior

A popup with an error message appears.

Expected/desired behavior

The user should be able to navigate to the desired cell, in order to add it as a reference to the formula.

Environment

Currently, only the List and Number validation rules are supported when using Workbook.ToDocument();

• https://github.com/telerik/kendo/blob/master/dpl/Telerik.Web.Spreadsheet/Models/Workbook.ToDocument.cs#L221 

It happens when the type of validation is text or custom 

for example:

If I saved :

"validation": {
                "type": "reject",
                "comparerType": "custom",
                "dataType": "custom",
                "from": "AND(LEN(A2)<3)",
                "showButton": true,
                "allowNulls": true
              }

I get back:

"validation": {
                "type": "reject",
                "comparerType": "equalTo",
                "dataType": "number",
                "from": "=AND(LEN(A2)<3)",
                "to": "\"=\"",
                "allowNulls": true
              }

It happens also when the comparer type is text - it saves it as a number

Also when I use the create validator with your UI and choose a custom formula it can't be saved because the compare type is null. As a result, I must define manually the custom validator

Tested on demo-page. The export of an Excel-file containing defined names with a period such as "test.name" will result in an error.

Steps to reproduce:

1. Create an Excel-file that has a defined name like "test.name"
2. Open the file on the demo page
3. Click on any of the "Save as..." buttons
4. An error page is shown

Bug report

Reproduction of the problem

1. Open the Dojo
2. In the first column enter "01/01/0001"

Current behavior

The Date is displayed as "12/31/0"

Expected/desired behavior

The Date should be displayed correctly.

Calling insertRow multiple times over many sheet data causes a slower performance since 2020.1.219.

Reproduction of the problem

http://dojo.telerik.com/EBEtaFOj (2020.1.114)

1. Click the Add Rows button and wait for the alert.

Current behavior

The Workbook.FromDocument() method freezes the panes based on the coordinates of the TopLeftCellIndex of the pane instead of the XSplit and YSplit properties of the pane. Reproduced with the attached Excel file

• https://github.com/telerik/kendo/blob/master/dpl/Telerik.Web.Spreadsheet/Models/Workbook.FromDocument.cs#L50

var pane = documentWorksheet.ViewState.Pane;
if (pane != null && pane.State == PaneState.Frozen)
{
    sheet.FrozenRows = pane.TopLeftCellIndex.RowIndex;
    sheet.FrozenColumns = pane.TopLeftCellIndex.ColumnIndex;
}

Solution:

var pane = documentWorksheet.ViewState.Pane;
if (pane != null && pane.State == PaneState.Frozen)
{
    sheet.FrozenRows = pane.YSplit;
    sheet.FrozenColumns = pane.XSplit;
}

WORKAROUND: Loading the Excel file with DocumentProcessingLibrary API and change the pane

var fileName = <YourFilePathHere...>;
if (!File.Exists(fileName))
{
    throw new FileNotFoundException(String.Format("File {0} was not found!", fileName));
}

Telerik.Windows.Documents.Spreadsheet.Model.Workbook workbook;
IWorkbookFormatProvider formatProvider = new Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.Xlsx.XlsxFormatProvider();

using (Stream input = new FileStream(fileName, FileMode.Open))
{
    workbook = formatProvider.Import(input);
    foreach (var sheet in workbook.Worksheets)
    {
        if (sheet.ViewState.Pane != null && sheet.ViewState.Pane.State == Telerik.Windows.Documents.Spreadsheet.Model.PaneState.Frozen)
        {

            var originalPane = sheet.ViewState.Pane;
            var pane = new Pane(new CellIndex(originalPane.YSplit, originalPane.XSplit), originalPane.XSplit, originalPane.YSplit, originalPane.ActivePane);
            sheet.ViewState.Pane = pane;
        }
    }
}
var sheets = Telerik.Web.Spreadsheet.Workbook.FromDocument(workbook).Sheets;

Bug report

This is a regression introduced in R2 2019.
Textboxes and charts currently are not supported in the Spreadsheet, however, if the loaded excel file contains such, saving the file should not throw a js exception.

Reproduction of the problem

1. In Excel add a textbox and/or a chart to a workbook. Save the workbook. Alternatively, use the attached file:
   sample-new-chart-textbox.zip
2. Load the .xlsx file in the Spreadsheet
3. Save the file

Current behavior

On saving the file the following exception is thrown:
kendo.all.js:12938 Uncaught TypeError: Cannot read property 'target' of undefined

Expected/desired behavior

No js exceptions on saving the file.

Bug report

If there is a Spreadsheet on a given page and we scroll the page down using the mouse wheel, once the scrolling stops over the Spreadsheet and we try to continue it, we cannot do it. If the Spreadsheet has defined rows that are not currently visible when the mouse wheel is moved, then Spreadsheet is being scrolled, not the current page.

If the Spreadsheet has a lower number of pre-defined rows that are all displayed on the component's initialization the scrolling is again not applying to the page. Instead, moving the mouse wheel doesn't do anything until the mouse cursor is moved outside the Spreadsheet.

Reproduction of the problem

1. Open this Dojo example and run it
2. Move the mouse cursor in the middle of the pane displaying the compiled code.
3. Use the mouse wheel to scroll down the page and stop the scrolling once the cursor is in the zone of the Spreadsheet
4. Scroll down again

Current behavior

Because the cursor is inside the Spreadsheet the page cannot be scrolled. If the rows configuration is commented, when the scrolling is started again, the Spreadsheet data will be scrolled.

Expected/desired behavior

If all the data in the Spreadsheet is displayed, moving the mouse wheel over the component should result in page scrolling. If there is data in the Spreadsheet, there should be some way to prevent the scrolling inside the component.

Hi Team,

I am using a kendospreadsheet. I want to find the rownumber of last non blank cell for column C.

When i try the =SUMPRODUCT(MAX(($C$1:$C100<>"")*(ROW($C$1:$C100)))) in excel it works.

The same formula does not work in kendospreadsheet.

Please suggest if this is a bug or if formula needs any change to fit the kendospreadsheet.

Regards

Bharathy B

Bug Report

When importing a XLSX file with a frozen pane using server implementation(using the Document Processing Library), the dimensions of the frozen pane are missed.  

Reproduction of the problem

1. Visit the Spreadsheet Server Import/Export live demo.
2. Import the attached example(FrozenPaneExample.zip).

Current Behavior

The imported xlsx file appears to overflow the Kendo UI Spreadsheet component.  See screencast(SpreadhsheetOverflowFrozenPane.zip)

Expected Behavior

When importing a file using server implementation, the file should be contained within the Kendo UI Spreadsheet component's view.

Workaround

Reduce the amount of frozen rows/columns to fit into the widget.

Bug report

Regression introduced in R3 2019.

Reproduction of the problem

Open this Spreadsheet demo. Even though the Toolbar configuration is set to false, it is not hidden. This applies only for ASP.Net Core and ASP.Net MVC.

Current behavior

The Toolbar is visible when set to false.

Expected/desired behavior

The Toolbar should be hidden.

Environment

Bug report

When we want to add a formula in a given cell in the Spreadsheet, we double-click it and enter the "=" in it as an identifier that a formula definition will follow. If we want to include in the formula a cell that is not inside the visible range of the Spreadsheet, we scroll to that cell and select it. In Internet Explorer, if we scroll to a given cell using the arrows of the Spreadsheet's scrollbar the "double-clicked" cell becomes just a selected one and the "=" sign is converted to a string value.

Reproduction of the problem

1. Open this Dojo example in Internet Explorer 11
2. Select the A1 cell and enter "=" in it.
3. Press the "down" direction arrow of the Spreadsheet trying to reach cell A50.
4. With the first click on the arrow, the A1 cell is no more "double-clicked" and the "=" inside it is converted to a string

Current behavior

When building a formula in a given cell and trying to navigate to a cell using the scrollbar, this usage stops the formula building and converts the "=" into a string.

Expected/desired behavior

When a user creates a formula for a given cell, they should be able to navigate through the Spreadsheet using its scrollbars.
