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] 

Indeed today, to correctly display red or other points depending on the template, it is necessary to make lines of codes so that the rendering is present.
It should be done automatically as soon as the array of dates changes (as it is linked to the calendar), I'm talking about the small calendar that is in the header of the scheduler.

I've found it frustrating to have to search for the definitions of types to find out if they should be instantiated as classes or interfaces.  Coming from C#, the convention there is that interfaces are named with and "I" as the first character.  So, IThing is immediately identifiable as an interface whereas Thing is obviously a class.  I do understand that this would break a lot of current code.   

Currently the Kendo AutoComplete only gives you the selected value, even though it received from the server a more detailed dataset.  The autocomplete really should be expanded to exposing the selected text and value, as well as expose the original data item that was selected; that way, the developer can access a lot more data from the control within the context of the change event.

The TreeMap widget does not correctly handle items with null values. See this sample code: http://dojo.telerik.com/@jmpg/IxEHub

It's possible to filter the DataSource to not have items with null values, but it would be much better if the TreeMap widget would simply ignore items with null or undefined values.

i tried your demo example :"http://dojo.telerik.com/" its works as well on Firefox 56.0 but does not work on IE11 nor on EDGE as planified.
the videos are concatened in the same web page instead to appear in the specidied frame.
please correct and  tell me the solution on my mail below.

When you set focus on a masked text box that has an existing value, the cursor position is reset to the beginning of the input - even if there is no mask.

I propose:

If there is no mask (i.e so its acting as free text) - don't reset the cursor position on focus, instead, behave like an ordinary input box.

The timezone should be adjustable [e.g. like in Moment Timezone date.tz('Asia/Tokyo')] or today should be accessible/configurable from outside the widget. Currently getToday() always returns the local time. Suggestion: Add the attribute today to the options and change the initialization of var today = new DATE() in getToday() to var today = new DATE(options.today) ...

We want the file upload control (chunk save method) to save the state while navigating between different pages sharing the same master page

Bottom navigation is obviously at the bottom in portrait mode, but on small screens in landscape mode it is detrimental to scrolled content.

It makes sense to keep bottom navigation on the small side of the screen but this requires to lock the app in portrait mode.

While allowing a change of orientation, it would be nice to have the option to show the bottom navigation on the right side and rotate the items when changing orientation to landscape and then back to the bottom when changing orientation to portrait.

some time we need to looking up in folder 
On telerik ASP.NET is call FileManager
We just need function like :http://elfinder.org/

Thanks

I'm trying to move my ASP.NET AJAX to Kendo MVC, but there is one way to customize the radioButton that doesn't translate to Kendo.  A picture/video would be more descriptive, but I'll just sent the html as that's my only option.  It toggles the multiple choices for the radio button, very intuitive for the user...  It would be nice to be able to do this on the Kendo side as well.

Returning only error messages from the validate method does not provide enough information to perform any meaningful processing of the errors - for instance, it is not possible to identify the field from a validation error without resorting to parsing the message

Develop a kendo form component and make edit field easy arrangement,just like bootstrap 12 grids system.the "popup" edit mode of kendo grid is not friendly when it has a lot of fields.The kendoForm component may be consist of form toolbar,form content and form footer.

Hi,

it would be nice if we can have a distinction between days when using a timelineWeek or timelineWorkWeek.

If you have a lot of ressources (with vertical grouping for example)  it could be difficult to see when a day is ending and the other is starting: see here.

It could be nice if we can have a border with a different css class (ie black color) that shows this behavior.

We did it on our side by using the slotTemplate but it's a kind of workaround that adds extra code/rendering time that could be done by the component itself on the first place.

Some ListBox widget ideas and proposals:

See screenshot: https://lh6.googleusercontent.com/TAVZGw63BSVVT6Nh8hXbiHerZ3L0krBzboONI07PpFByROeqKPiFgrlaPnTMtIUZ94D8xRog=w1920-h960

1. Add two search fields, so it is possible to search within the left and right panes individually.
2. Add headers above the search fields. They can be configured via templates. Also add options for selecting/deselecting all items in the corresponding pane. Checkbox’s middle state should also be considered.
3. Add option (API) for enabling/disabling ListBox widget as a whole widget (similar to DropDownList, ComboBox, etc.), not only item by item.
4. Add support for data virtualization (similar to DropDownList, ComboBox and AutoComplete).
5. Add API (public methods or fields) for retrieving the current status of the items in the ListBox. For example:
- a method/property which returns the count of currently selected items
- a method/property which returns the count of currently showed items (if searching, not all items will be visible)
- a method/property which returns the count of total items
This information can be shown in the headers via template, for example.

The listview endless scrolling is a neat feature but it will be good if we could configure it to be in reverse. We are building chat system in our app and want to have the endless scrolling widget but need it to scroll in reverse.

Add columns to timepicker to have multiple columns instead of a long list.
Like you have for the Telerik Ajax Timepicker 

All controls which work with Models (validation/grid etc) should recognize displayName instead of field name to allow localization.

Model.define({
     fields: {
              Description: { type: "string", displayName: "Beschreibung", validation: { required: true, maxlength: 200 } },
              Number: { type: "number", validation: { min: 0, max: 300 } }
     }
   });
