When a column is set to sticky in a grid and the user clicks edit and then cancel, that column become unsticky for that row only. This happened when I upgraded from 2022 to 2024 so the bug was created somewhere in there. To reproduce, see this dojo: 
https://dojo.telerik.com/@dojolee/evOPeBey

1. Shrink the right side of the screen until it is pretty small (about 700px)
2. Click Run and make sure there is a horizontal scroll. If not, shrink the right and click run again.
3. Scroll and notice that the first column sticks
4. Click edit on the first row
5. Click cancel
6. Scroll and notice that the first row no longer has a sticky column.

Greetings!

I'm not sure if this is related to another bug report I submitted (https://feedback.telerik.com/kendo-jquery-ui/1656256-daterangepicker-clicking-end-input-now-changes-range-end-instead-of-forcing-users-to-select-full-range), but I noticed that after selecting the End date, the input retains focus. Clicking out of that input will trigger an extra change event. To illustrate, consider this sequence of events:

1. Select a Start date → first change event.
2. Select an End date → second change event.
3. Blur the End input → third (extra) change event.

This applies to version 2024.2.514 (see Dojo example for your consideration: https://dojo.telerik.com/EbuVoHIJ).

There would appear to be a similar bug that applies to some previous versions of Kendo UI for jQuery (I only tested as far back as version 2024.1.130):

1. Select a Start date → first change event.
2. Select an End date → second change event.
3. Click the End date to open the DateRangePicker again.
4. Without changing the value, click out of the DateRangePicker → third (extra) change event.

Note that repeating steps 3 and 4 again will not trigger any more extra change events until one of the values is actually changed.

Image browser invalidFileType error contains " since 2023.2.718

Reproduction of the problem

https://demos.telerik.com/kendo-ui/editor/imagebrowser

Expected/desired behavior

No " shall be present in the error message when an unsupported format is selected

Environment
**Kendo UI version: 2023.2.718 or newer
**jQuery version: 3.7.0
**Browser: [all]

Clicking an item in the parent list reveals the child list that replaces the parent list.

At the top of the child list, there is a < back item that allows returning to the parent list.

For examples, see the drawers at:

• https://www.amazon.com/
• https://www.diy.com/ (make the window small enough to display the drawer button)

add delay parameter in miliseconds for the kendo.ui.progress so you don't see your container blinking if your ajax calls are fast.

Bug report
Grid - Frozen Columns - 'lockable' property being ignored with Drag to Lock/Unlock

Regression introduced with 2023.3.1114

Reproduction of the problem
Open this Dojo example - https://dojo.telerik.com/ovaHinas/4

Drag a column from the locked section to the unlocked one

Expected/desired behavior
No drop shall be available.

Environment
Kendo UI version: 2023.3.1114 or newer
Browser: [all]

I have a requirement to show parent rows below the child rows, such that when a parent row is expanded the children show up above the parent. Currently from the options, it seems that parent row can only be expanded to show children below the parent. This is not supported by the grid or treelist, and Kendo support has requested this be logged as a feature.

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

I can see many people are asking to have smart labels in kendo chart also, so do you have any planning for same or can you share the logic of smart labels?
I have multiple series in the chart like 2-3 lines, 1-2 bars etc and their series labels are overlapping badly.

Check attached screenshots.

Bug report

Setting an empty string value when using an MVVM ColorPicker throws an error

Reproduction of the problem

1. Open the following dojo.
2. Notice that the ColorPicker produces an error when the value from the Observable object is set to an empty string.

Current behavior

Setting an empty string through the Observable object throws an error within the console.

Expected/desired behavior

Setting an empty string through the Observable object should not throw an error within the console.

Add a new Kendo UI component to display a record vertically (Or add an option to the existing grid to change the orientation of the records).

Usually, I was using vertical grid to display a single record but some people might need it to display more than one record (ex: when you compare items on best-buy web site)

The vertical grid could also be used as a property grid (http://www.telerik.com/products/silverlight/controls/propertygrid.aspx).

Bug report
ExpansionPanel control is not collapsing/expanding when set up collapseIconClass

Regression since R1 SP1 2023

Reproduction of the problem
Dojo: https://dojo.telerik.com/AqOrUKib

Expected/desired behavior
The user shall be able to set expand and  collapse icons

Environment
Kendo UI version: 2023.1.314 or newer

I'd like to request adding a clear button similar to the Kendo UI ComboBox for the Kendo UI TextBox.

Thank you!

The children of a node (if the children are all leaf nodes) vertically stack when parent is expanded. Can you add a setting that forces horizontal sibling orientation for leaf nodes.

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>

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.
