Context: There is an item that illustrates the issue here: https://www.telerik.com/forums/kendo-datepicker-value-not-populated-after-refresh-firefox-only

In Firefox, when using the asp-for tag helper to bind a c# DateTime field to an input element, then calling kendoDatePicker() on that element, the control fails to populate on a soft-refresh (F5). Upon reloading using F5 in Firefox, the input's type is set to datetime-local, and the input 's control variation is changed to the default date picker.  Then, the Kendo UI DatePicker is initialized with a blank input which normally has a type of text. 

Example project and video of issue are attached.

This is the pertinent code (also happens in latest version of Kendo as well):

    public class IndexViewModel
    {
        public DateTime DateAsDateTime { get; set; }
    }

        public IActionResult Index()
        {
            return View(new IndexViewModel { DateAsDateTime = DateTime.Today });
        }

@model IndexViewModel

<input id="dtDate" asp-for="@Model.DateAsDateTime">

<script type="text/javascript">
    $(document).ready(function () {
        $("#dtDate").kendoDatePicker();
    });
</script>

Email address lists - and other list inputs for text items - in various apps take text input and render each item in a tag - not unlike the MultiSelect.

A widget in similar form to the MultiSelect could serve this purpose, taking string input from the text input element - as well as being able to filter on active text.

I have rigged a MultiSelect with a view model to perform this function: dojo example. Its not perfect, but seems to work ok.

• ";", "," and space characters are used as string separators to trigger parsing - and split text e.g. from pasted list
• a simple email RegEx rejects values that cant be an address
• email addresses are added to the "available item" list and selected item
• the available items can be pre-populated according to the context
• like in the MultiSelect, the pop-up list can be displayed and filtered as the user types
  
• the pop-up list can be used to de-select and re-select items, as well as tag clear and "clear all" buttons in the widget
• similar keyboard support is useful, "Ctrl-A", arrow keys etc.
• multi and single tag modes

Our clients are requesting that the search in the multiselect look like the search in the dropdownlist. They want it to be in the list that opens rather than in the value box and want a consistent operation and look. This should be an option that can be set when initializing the multi-select. I attempted this using the forum post below but it is quite buggy and requires a lot of modifications.

Bug report

The DropDownTree allows us to configure its checkChildren and filter options. Both options are working correctly, when used separately.

When the two options are defined for the DropDownTree, the checkChildren options don't select the child elements of a given node that is checked.

Reproduction of the problem

1. Open this Dojo example
2. Expand the DropDownTree popup
3. Check the "Furniture" node checkbox

Current behavior

Only the "Furniture" checkbox is being checked

Expected/desired behavior

The "Furniture" and all of its child nodes should be selected when clicking on the "Furniture" checkbox.
Here is a Dojo example in which the checkChildren configuration is working as expected.

Environment

• Kendo UI version: 2022.1.412
• jQuery version: x.y
• Browser: [all]

In the latest version of Kendo UI, various input controls like the NumericTextBox or the ColorPicker now consist of an input field and a button control (used for increasing/decreasing the value or opening the dropdown).

The border-radius for those widgets can be controlled by setting the "rounded" option. At the same time, when using SASS themes, a button's default border-radius might be set using the $kendo-button-border-radius variable. The buttons inside e.g. a NumericTextBox do not override the theme's border-radius which leads to an outcome like this:

Widgets that use Buttons internally (and therefore offer no way of overriding the button's border-radius by setting its "rounded" option manually) should override the default styles.

Unfortunately, I could not reproduce the behavior in a DOJO, because I cannot transpile SASS themes there.

The Kendo Spreadsheet is bound to a Kendo datasource, the datasource defines a schema, but when the JSON comes back the spreadsheet just ignores the schema properties and dumps the entire thing into the sheet.

It would be nice to not have to code up some additional workaround after already having defined the schema I want.

(No control over the JSON structure from the server)

• Currently, when the legend has a lot of items or the labels are too long, it will create multiple lines and takes spaces. We would like to keep the legend in one line as fixed and add a scrollbar within the legend.
• This will make the chart more clean and the legend wont overtake the space of the chart and it will remain the same size no matter how many items it contains.

Expose the ability to alter default icon content. Similar to how it can done in the Kendo UI for Angular suite - https://www.telerik.com/kendo-angular-ui/components/icons/icon-settings/#toc-svg-icons

I would like be able to have a vertical scrollbar on a kendo grid without enabling horizontal scrolling.

Currently when the scrollable feature is set to true, scrolling is enabled for both horizontal and vertical.

I would like to see something like:

scrollable:{ vertical : true, horizontal: false }

Can that be done?

Thank you!

Hi,

When I double click a cell and enter into editing mode, scrolling up or down will make the editor div out-of-place. 

It should follow the target cell instead.

This can be easily reproduced here: https://demos.telerik.com/kendo-ui/spreadsheet/index

It seems Kendo UI for Angular/React also have the same issue.

Kendo UI ImageEditor, jQuery version. Add Draw simple shapes and text over image like you have in the WPF image editor component.

I saw a slightly similar request but not exactly what I would like.

Thanks, Kurt Miller

Please add the following things in Kendo UI
validators for compare, password length check, password complexity check, RangeValidator, ValidationSummary

Having a character counter for textbox & textareas gives users nice little heads up as they start typing to summarize the text for a fixed length. Not sure about internet applications but its becoming more & more a requirement in business applications. Please give it a thought.

kendo.all.min.js is reporting this in Chrome.

A page or script is accessing at least one of navigator.userAgent, navigator.appVersion, and navigator.platform. In a future version of Chrome, the amount of information available in the User Agent string will be reduced.

To fix this issue, replace the usage of navigator.userAgent, navigator.appVersion, and navigator.platform with feature detection, progressive enhancement, or migrate to navigator.userAgentData.

Note that for performance reasons, only the first access to one of the properties is shown.

When will this be resolved?

It would be a great help if there was a way to add a Trendline to a line chart in the DataViz collection.  This function is available in excel and other similar programs.  
The wiki page explains:
http://en.wikipedia.org/wiki/Trend_line_%28technical_analysis%29

Reproduction of the problem

1. Follow the steps described in the link here - https://github.com/telerik/kendo-ui-core?tab=readme-ov-file#building-kendo-ui-core
2. Create a custom script for validator npx gulp custom -c validator
3. Try to load the script and create the components

Current behavior

The validator is not working, error is shown

jQuery.Deferred exception: $(...).kendoNumericTextBox is not a function

Expected/desired behavior

The components should work as expected when custom script is created
