Dojo example.
All filters are cleared.
The Spreadsheet shows Company filtered by value "Excella". This is the behavior when different columns are filtered consecutively and then "Undo" is clicked.
If you want to have only some of the default tools, you cannot do that with the Spreadsheet wrapper.
.Toolbar(t =>
{
t.Home(h =>
{
h.ExportAs();
});
})
All the tools are displayed.
Only the ExportAs tool is displayed.

A js exception is thrown:
Uncaught TypeError: Cannot read property 'click' of undefined
kendo.all.js:168073
With the toolbar disabled the shortcuts should do nothing. There should be no exceptions.

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();
}
The Save method throws System.ExecutionEngineException
The file is saved.
Regression introduced in R3 2019.
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.
The Toolbar is visible when set to false.
The Toolbar should be hidden.
Reproducible in the demos:
A popup with an error message appears.
The user should be able to navigate to the desired cell, in order to add it as a reference to the formula.
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();
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:
Hi There,
I am facing one issue in kendo spreadsheet onchange event.
Suppose I have applied formula on one cell A1 and formula is =SUM(B1:B3)
Now one change of values in B1 to B3 on change event gets fired but whenever cell A1 values gets updated i.e. on entering value in B1 to B2, on change event doesn’t get fired.
How can I make onchange event fire for formula cell.
Thank you,
Rakesh
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
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;
The Date is displayed as "12/31/0"
The Date should be displayed correctly.
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.
On saving the file the following exception is thrown:
kendo.all.js:12938 Uncaught TypeError: Cannot read property 'target' of undefined
No js exceptions on saving the file.
Calling insertRow multiple times over many sheet data causes a slower performance since 2020.1.219.
