provide option to make search input in listview fixed on top while user is scrolling.
When exporting data to an Excel spreadsheet, unsanitized data can be used to trigger a formula-injection attack. For example, a malicious user could embed a formula in a normal business object field (eg. description of a movie), then wait for a unsuspecting user to export the data to Excel. When the file is open in Excel and the cell is clicked, the formula is executed on the user machine, which can be used to do bad stuff (execute commands, exfiltrate data...). While latest versions of Excel has added a lot of warning when you open spreadsheet, it often recommend to open the file only if the user trusts the originating web site, which is normally the case.
One way to mitigate the issue is to prepend a single-quote to a value in Excel, which neutralize the formula and force the value to be interpreted as a string. The single quote is not shown in the Excel grid, but is visible in the formula bar.
With Kendo UI for jQuery, we can modify the data on the fly to prepend a single-quote, which does neutralize formula, but the single quote is shown in the Excel grid.
To obtain the same behavior as Excel, we need to use the quotePrefix cell format in Office Open Xml (see quotePrefix in this link).
Hence, I would like to have something similar to the following feature in Kendo UI ooxml module:
- Add a property to cells (https://docs.telerik.com/kendo-ui/api/javascript/ooxml/workbook/configuration/sheets.rows.cells), similar to other styles (italic, wrap...), called quotePrefix, that takes a boolean value (default=false)
- When that property is 'true', add 'quotePrefix="1"' to the cell style in the generated OpenXML spreadsheet (inside "cellXfs / xf" elements)
I think the effort would be minimal, and it will yield far better experience for users when server tries to overcome the fomula-injection problem.

I am looking for the kendoui heatmap chart as found on GitHub or at the URL above.
I could just copy what they use on github, but I would prefer to get the kendo CDN all from one place.
Initial usage is just to render activity throughout the day as in github, extra is to track the onClick events as you usually want to trigger a re-query on what happened in that period of the day on that date, driving a details view elsewhere.
Al worse you could have dojo demo of how you would wire up chartjs-chart-matrix to a the Datasource(eg like https://demos.telerik.com/kendo-ui/map/geojson), with a view of how you would have created such a chart that would be good on a PWA app.
Thanks

Bug report
When the content that is being exported to PDF contains Material Design Icon the exported PDF is not valid.
Reproduction of the problem
- Open the Dojo
- Export the file
- Try to open it with Adobe Reader
Current behavior
Currently, when the file is about to be opened with Adobe Reader the following error appears - 'An error exists on the page. Acrobat may not display the page correctly. Please contact the person who created the PDF document to correct the problem.'.
Also if the file is tested in an online pdf validator it is not considered valid.
Expected/desired behavior
The exported file should be opened in Adobe Reader without any issues.
Environment
- Kendo UI version: 2021.1.330
- Browser: [all ]
When a kendoContextMenu is applied to a combobox (html tag select) you are not able to show the select options by tapping it. The behaviour is on mobile browser only (tested iPad and Google Chrome developer tools with device toolbar enabled).
I reproduced the issue in telerik dojo, here is the code.

Currently, the data-value-update attribute can be used on DOM elements: https://docs.telerik.com/kendo-ui/framework/mvvm/bindings/value#controlling-the-view-model-update
It would be nice, if we have the ability to use it with editor widgets like TextBox, TextArea, NumericTextBox, etc.
Since we get no real intellisense with javascript, I would love it if you guys could work with the JustCode team to implement templates, or syntax checking, or KendoUI highlighting. The cross-promotion would help both teams sell product, no?
Currently Kendo only supports TrueType fonts for embedding in PDF files. OpenType support would be great since it's a more modern format overall, and there are many fonts that are only available as OpenType (for example Google's Noto fonts).
Textbox control which keeps extending until we finish typing. something like what iOS have when we want to add note in contact.
Now, I am doing with the Spreadsheet. I have a problem.
When I change font to Japanese, and then I enter characters to cell.
The first character was disabled, other characters displayed normally.
It only cause with Japanese font.
Please help me about this problem
Hi,
I want simply a way to check that the cell value is valid when the user presses submit button on the page.
Currently, validation works when a value is entered in a cell by the user. I want validation to work when the value is changed through a formula. or i need a function that i can run manually that tells which cell validation has failed.

It would be good to have the export hierarchy grid to CSV format as build-on support.
I have referred couple of articles and dojo, but didn't find any straight forward solutions.
It would be very nice if we could export a chart (and its data) to Excel.
On one hand, kidoju.mobile has not progressed in several years.
On the other hand, some "mobile" controls like Bottom Navigation and Floating Action have entered the realm of kendo.ui, and an Action Sheet is in the roadmap.
Some of us still develop/maintain hybrid apps. It has become necessary to (i) clarify the roadmap and (ii) get some new best practices (doc and samples) for developing hybrid apps with Kendo UI (kinetic scrolling via mobile scroller, ...).

Some of us still develop/maintain hybrid apps. It has become necessary to (i) clarify the roadmap and (ii) get some new best practices (doc and samples) for developing hybrid apps with Kendo UI:
- should we discard all kendo.mobile.ui widgets and replace them with their equivalent kendo.ui widget?
- how to replace certain widgets like kendo.mobile.ui.scroller which have no equivalent for kinetic scrolling.
Currently, when you open an existing Excel file in the Kendo UI spreadsheet, make some changes, then post the changes back to the web server, the print and scaling settings of the original Excel file would be lost.
The Kendo.ooxml.Workbook should preserve those settings.

Message from Aleksandar
Calling the saveAsExcel() method triggers the excelExport event. The Kendo UI Spreadsheet utilizes the Excel export module framework to produce Excel files directly in the browser. The output files are in the OOXML Spreadsheet format with an .xlsx extension as explained here. Setting the forceProxy configuration to true will send the ooxml generated export file to the remote endpoint. However, the kendo.ooxml.Workbook API does not expose a configuration option that would preserve the option for setting the page scaling when printing, thus the configuration is lost. If you would like to see such an option available I can suggest logging a Feature Request in our Feedback Portal.
Hello ,
I've been struggling to fix a problem , but it seems it's a bug from Kendo
the scenario is , when I had two events for same resources (I made a vertical grouping for ressources) then I moved on of the events to another slot it moved but the slots misaligned and the same thing when I remove an event
I will include a screenShot to see that
You can currently set series labels to position "center" on the pie chart to get them to render on the slices, but sometimes slices are too small to contain these labels. It would be great if there were an option for the chart to detect when a slice is too small and render the label outside the chart, while still rendering labels on pie slices that are big enough to contain them.
Support for injecting some custom header information in the export PDF and Excel? e.g. You are exporting some grid to excel or pdf and you want do display the search parameters in the header of the document.
