Reproduction of the problem

If you want to have only some of the default tools, you cannot do that with the Spreadsheet wrapper.

1. Declare the tools you want, e.g.,

.Toolbar(t =>
{
	t.Home(h =>
	{
		h.ExportAs();
	});
})

Current behavior

All the tools are displayed.

Reported in Ticket ID: 1529288

Reproduction of the problem

Create an MVC application:

View:

@{
	ViewBag.Title = "Home Page";
	string sfile = System.IO.Path.Combine(Server.MapPath("~"), "File1.xlsx");
}

@Html.Kendo().Spreadsheet().Name("spreadsheet"))

<br />	
<br />	
<button class="k-button k-primary" id="export" onclick="ExportExcel()">Export Spreadsheet content</button>
<script>
    function ExportExcel() {
        var spread = $('#spreadsheet').getKendoSpreadsheet();
        var data = JSON.stringify(spread.toJSON());

        var fd = new FormData();
        fd.append('wbook', data);
        fd.append('sfile', "File1.xlsx");

        $.ajax({
            url: "@Url.Action("SaveFileExcel", "Home")",
            data: fd,
            contentType: "application/x-www-form-urlencoded",
            processData: false,
            contentType: false,
            type: "POST",
            statusCode: {
                200: function (xhr, status, err) {
                    console.log('File exported!');
                },
                500: function (xhr, status, err) {
                    console.log('Internal Server Error!');
                }
            }
        });
    }
</script>

Controller:

[HttpPost]
public ActionResult SaveFileExcel(string wbook, string sFile)
{
    var workbook = Telerik.Web.Spreadsheet.Workbook.FromJson(wbook);
    string physicalPath = Path.Combine(Server.MapPath("~/"), sFile);
    //workbook.Save("C:/inetpub/wwwroot/" + sFile
    workbook.Save(physicalPath);
    return new EmptyResult();
}

1. Add the application to a Docker container.
2. Place a breakpoint in the SaveFileExcel action.
3. Run the app and click the button below the Spreadsheet.

Current behavior

The Save method throws System.ExecutionEngineException

Expected/desired behavior

The file is saved.

Environment

• Kendo UI version: 2021.2.616
• jQuery version: x.y
• Browser: [all]

Bug report

Reproduction of the problem

Dojo example.

1. Open Company filter menu.
2. Uncheck All and check only "Excella". Click Apply.
3. Open the same filter menu and check "Complete Tech". Click Apply.
4. Click the "Undo" button

Current behavior

All filters are cleared.

Expected/desired behavior

The Spreadsheet shows Company filtered by value "Excella". This is the behavior when different columns are filtered consecutively and then "Undo" is clicked.

Environment

• Kendo UI version: 2021.2.616
• jQuery version: x.y
• Browser: [all]

Bug report

Reproduction of the problem

Reproducible in the demos:

1. Create a second sheet.
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

• Kendo UI version: 2021.2.511
• jQuery version: x.y
• Browser: [all]

When the Scheduler control is bound a datasource that includes a Boolean value/column in the database the Spreadsheet column presents this as "true" or "false" strings.

Allow alternate strings such as  "Yes" or "No" to represent a Boolean. Would of course need to update the datasource appropriately on Edit of a cell that uses this presentation.

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;
