Step by step instructions on how to reproduce the problem:

1. Create a kendo tab strip
2. Using the append method, add a "tab1"- do not specify any content in this new tab
3. Using the insertBefore method, add a "tab2", this time specify some content
4. Attempt to navigate the tabs and note what is showing in the content of each tab

Code snippets:

            var tabStrip = $("#contentlessAppend").kendoTabStrip({}).data('kendoTabStrip');
            tabStrip.append({
              text: "noContentAppend",
              //content: "With content" //Uncomment this line for normal functionality
            });
            tabStrip.insertBefore({
              text: "contentInsertBefore",
              encode: false,
              content: `<div id="WhereAmI">I am not where I should be</div>`
            }, tabStrip.tabGroup.children().eq(0) );

Bug report

When a culture that uses a "comma" as a decimal separator is applied to the Kendo UI NumericTextBox, the value of the aria-valuenow attribute uses the value without transforming the "," separator into a "." separator.

Reproduction of the problem

Set a culture that utilizes the comma as a decimal separator. Notice the aria-valuenow attribute's value:

https://dojo.telerik.com/okoJIRID

Environment

* **Kendo UI version:** 2020.2.617
* **jQuery version:** 1.12.4
* **Browser:** [all] 

The core library should provide a kendo.parseBoolean function such as kendo.parseInt and kendo.parseFloat etc. With such a function, e.g. Configuration settings from AppSettings.config can be conveniently parsed.

Sample: https://jsfiddle.net/chstorb/rxo6hnud/

Hi Team,

I would like to request a Kendo UI Avatar for jQuery similar to the Kendo UI for Angular.  

Thanks!

Feature request for the Gantt chart. I’d like to be able to attach objects (thumbnail images) to the Gantt hourly timeline. 

I have multiple thumbnail images and each thumbnail has a timestamp. I want to attach the thumbnails on the timeline according to the hourly timestamp of each thumbnail.

Gantt chart should support attaching objects to timeline.

Describe the bug
The TextArea has 14 px font-size and the other inputs have 100% font-size.

Reported in: 1486377

To reproduce
https://dojo.telerik.com/iLeZIpEz

1. Use the LESS-based theme.
2. Implement a TextArea component.
3. Implement a TextBox component.

Expected behavior
The font-sizes for the TextArea and the TextBox have to be equal.

Environment

• Kendo UI version: 2020.3.915
• Browser: [all]

Hi Team,

I'd like to request a control which takes a screenshot of a browser's page and save it in a specific format like a jpeg.

Thank you

I would like to request that an autosize feature be added for the dropdown portion of the multicolumncombobox in Kendo UI for jQuery. 

I had been using the kendo jquery dropdown autowidth and had expected a similar functionality to be available and was surprised that it wasn't.  I have used winforms ui multicolumncomobobox in the past and it has some different fill/autosize/fit abilities. 

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.

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.

From Ticket ID 1513253

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.

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.

Hi Team,

I'd like to request for the Kendo UI to be able to facilitate its stylings along with the BootStrap form-control class.  This way, I will not need to add any additional custom CSS for certain components within Kendo UI(TextBox, NumericTextBox...etc). 

Thank you!

Table editor allows to select multiple cells, horizontally, vertically, or even individually while holding down the Ctrl-key.

If based on such selection the table wizard is opened, one would expect that any choices made would apply to all the selected cells.
Instead, the changes are applied only to the first cell.

Please, either disallow selecting multiple cells or better allow batch editing of the selected ones.

Hi Team,

I'd like to request the functionality to set the scrollbars of the Kendo UI Components to a smaller size instead of the default larger scrollbars.  For example, something similar to jquery.nanoscrollbars.js.  

I do understand CSS doesn't currently support styling scrollbars:

https://drafts.csswg.org/css-scrollbars-1/#intro

It can be done using the ::-webkit vendor prefix, which works for some browsers but not IE or Edge.

The CSS working group say that : Note: Exposing the scrollbar-related ::-webkit- prefixed pseudo-elements to the Web is considered a mistake by both the CSS Working Group and Webkit.

At the moment, the only recommended way is to use javascript to "polyfil". Nanoscroller is one such example.  http://jscrollpane.kelvinluck.com/ is another example.

The controls just need a kendo's own polyfill, not to implement nanoscroller or jscrollpane, but for kendo to do it by itself out of the box.

Small controls with big scrollbars looks ugly. 

Thank you!
