Bug Title: Columns are not programmatically associated with their table headers.

Severity: Sev2 (High)

Test Environment:
OS Version: 22H2 (OS Build 25352.1)
URL: https://ppe.oneidentity.core.azure-test.net/
Edge Dev: Version 114.0.1807.6 (Official build) dev (64-bit)
Screen Reader: Narrator

Repro steps:
1.Open kendoSample (codepen.io)
2.Navigate through tables.


Actual Result:
Table header and their data are in different tables. Columns are not associated programmatically with their headers.

Expected Result:
Columns should be associated programmatically with their headers.

Environment (OS, Application, Versions): 

OS Version: 22H2 (OS Build 25352.1)
Edge Dev: Version 121.0.2277.112 (Official build) (64-bit)

Third Party Name:   Kendo

Repro Steps: 

   1. Open https://codepen.io/oneID/pen/LYaGREP and turn on NVDA.
   2. Navigate to 'Populate' grid and activate it using enter key.
   3. Navigate to Expand button present under domain in Export to excel table.
   4. Observe if the screen reader is announcing correct role and name for the expand button or not.

Actual Results: 

Accessible name for the 'expand' button is not correct, Expand button is defined as link.

Expected Results:

Accessible name of 'expand' button should be sufficient for screen reader user. Accessible name should contain value available in domain as well.

Role should be defined as 'Button' as its behaving as button.

We are using a sheet with a datasource

if the user only selects one column and then sorts it only sorts the data in that column and mixes the rows data. 

Suggestion: the filter button should act like the Excel filter button where it auto selects the entire sheet before applying the filter.

Maybe only when using a datasource?

Example: https://runner.telerik.io/fullscreen/yypoqSea

This example is based on the example from the docs with `navigatable: true` and enough data that the user needs to scroll in order to see the bottom row.

On Chrome on macOS, the filter menu cannot be used when `navigatable: true` and "Tap to click" is enabled in the macOS Trackpad settings. When clicking on the filter icon, the menu disappears very quickly (see screen recording). As a workaround, setting `navigatable` to false seems to resolve the problem. The same issue does not seem to occur on Safari, however, there is still odd behavior with the scrolling.

For some reason, screen size, resolution, and window settings impact the ability to reproduce the issue. The most reliable way for me to reproduce the issue was with Chrome in full screen on a 16-inch MacBook (13-inch works too) with the bookmarks bar showing and no external displays connected. Hiding the bookmarks bar or not using full screen seems to make it more difficult to reproduce.

Kendo UI core lists several controls that are available in the library, but there is no mention that they are not actively maintained on main repository readme.

Several controls were obsoleted/unsupported in this commit - https://github.com/telerik/kendo-ui-core/commit/db16f60ee6ee43506173a9628723b3de1ed73266, but they are still listed in https://github.com/telerik/kendo-ui-core/blob/master/README.md or promotional graphics.

Please clarify its current/future status.

Best regards

See demo page: https://docs.telerik.com/kendo-ui/api/javascript/ui/colorpicker/configuration/clearbutton

The example uses "<input id="colorpicker" type="color" />".  Opening the preview reveals a black color.
Change the input-tag to div and the 'clear'-style is presented in the preview.
Or remove the color type when using the input-tag: "<input id="colorpicker" />" also correctly represents clear.

I can also locally reproduce it with Kendo UI jQuery v2024.4.1112.

Requesting a modification to any component that uses k-animation-container.

Some components have this capability:

popup: {
    appendTo: $("SOME ID")
}

This gives us the ability to modify CSS for a single/particular popup. Please add this ability to all relevant components.

Or any other method to modify the styling of a particular dropdown. In some cases, there's an ID that's added but is removed for some reason when adding a certain configuration.

Hi Team,

I would like to request a way to configure the Kendo UI Grid so if there are multiple footers from many groups, only one footer will show. 

Thank you!

I'm getting inconsistent behavior when testing a ComboBox with Virtualization enabled. I've tested with both the ASP.NET Core demo and the jQuery demo. The .NET demo defaults to version 2024.2.514 and the jQuery defaults to the current version (2024.3.806), however I've tested with several different versions in the jQuery demo and they all yielded the same results.

Note: if you're unable to recreate any of the problems below, try refreshing the demo page and trying again. When additional data is loaded into the list via Ajax requests (ex. after scrolling through the list), this can interfere with the tests below. Refreshing will ensure there is no additional data from Ajax requests and only the data that was initially loaded into the list (the first 80 results).

Königlich

If you copy/paste the value "Königlich" into the textbox, the list of options is displayed with a matching option listed first (everything is working as expected so far):

If you hit backspace, however, the list of options is updated and the first option no longer matches (at all):

If you hit backspace again, the list of options is updated again, and now the matching value is back:

Backspace again, matching option disappears and the bad one is back:

It alternates like this each time you hit backspace, bouncing between a good matching value and a bad one that seems completely unrelated.

Queen

If you enter "Q", the list opens and the first option listed matches:

Add a "u" and the first option is no longer the match. However, the matching option is listed halfway down the list. Note that with Königlich above, this was not the case (notice in the screenshots above the first option has a border around it; there was no option in the middle of the list with a border).

Add "ee" ("Quee") and you're left with no more matches:

However, if you open the list and scroll down to 10372, you'll find there is in fact an option for "Queen" available that the previous entry wasn't finding:

Bon app

If you enter "B", the first option listed is a match. If you add an "o" ("Bo"), you're left with no matches:

But if you scroll down to 10331, there's an option for "Bon app" listed that wasn't matched above:

Blauer See Delikatessen

Same as above. Entering "Bl" finds a match, but "Bla" does not. Open the list and scroll down to 10501 to see the option that should have matched.

Summary

There seem to be several issues here:

1. Alternating between finding a matching value then finding a random value as each character is entered (most prevalent with Königlich).
2. Some options cannot be found via filtering (ex. all but the first above). Not only is it not running Ajax requests to find matches in options that haven't been loaded yet, but it also doesn't appear to find matches in options that have already been loaded via Ajax.
3. Matched option displayed in the wrong location (in most cases the match was displayed first in the list, but in one of the examples above it's in the middle of the list).

When I incell edit multiple rows I only receive a sync callback through `change` on the datasource for the last row with only that last row in the "changedItems". This results in the grid not removing the dirty indicator for any of the other rows, only the last one is removed. The rows are updated properly and I if I were to manually call grid.refresh() it removes the indicators. If I update the rows individually it has no problems.

Here I've updated only the first row:

Here I've updated only the second row:

Here I've updated the first 2 rows at the same time and only the last one is detected as updated:

Here I've updated the PRS column for all 4 rows to "5" and it saved correctly, but only the last row is detected as updated in the grid:

As there's a lot of code involved I can't just paste it here, I can provide snippets or information about particular settings though.

In current versions of Firefox, scrollbars do not longer reserve any space. In grids with locked columns, this leads to a double border at the right end of the grid's header:

The problem only appears if locked columns are present and scrollbars use zero-width (Firefox-Default). This DOJO contains a minimum reproducible example.

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.

Hi Team,

Is there a way to create pop up create and inline edit. 

Thanks,

Event "Select" is triggered on dropdown list when user do a middle click on the part outside of the list, event the popup of list isn't opened.  

When using Kendo's Upload component when you select a file/files to upload there is a 20% chance that it will upload the same file twice. We switched auto upload off to help, but when you delete one of the dupped files the upload button disappears causing you to delete both of them and then re-upload the file.

Upload Code -

 var w = $("#winFiles").data("kendoWindow");
                w.setOptions({
                    width: $(window).width() - 150,
                    height: $(window).height() - 150
                });
w.center().open();
                $("body").on("click", "#lnkShowUpload", function () { showWinUpload(associationId, typeId) });

function showWinUpload(associationId, typeId) {
var w = $("#winUpload").data("kendoWindow");
    $("#fileUpload").kendoUpload({
async: {
                        saveUrl: `/api/File/?typeId=${typeId}&associationId=${associationId}`,
                        autoUpload: false
                    },
                    validation: {
                        allowedExtensions: ["pdf", "jpg", "img", "png", "gif", "doc", "docx", "xls", "xlsx", "csv", "txt"]
                    }
});
                w.setOptions({
                    height: $(window).height() - 175
                });
w.center().open();
}
