The built-in kendoDropDownFilter directive normalizes text using String.prototype.toLowerCase() when caseSensitive: false. This is locale-insensitive and produces incorrect results for languages with non-standard case-folding rules, most notably Turkish.

The correct fix is to use String.prototype.toLocaleLowerCase(locale), which respects locale-specific case rules. The DropDownFilterSettings interface should expose a locale option for this:

filterSettings = {
  caseSensitive: false,
  operator: 'startsWith',
  locale: 'tr-TR'   // ← proposed new option
};

Affected components: kendoDropDownFilter directive (used with AutoCompleteComponent, ComboBoxComponent, MultiColumnComboBoxComponent, DropDownListComponent, MultiSelectComponent).

Signal Forms are now stable with Angular@22.

It would be nice to have an ability to use all kendo widgets with new form API.

For the Kendo DatePicker, if you try to set the size on a kendo-datepicker with plain text, it will not render and give a console error of "ERROR TypeError: Cannot read properties of undefined (reading 'nativeElement')".

Errors:

// HTML
<kendo-datepicker size="small" ... />

---

But on the other hand, it does work if you create a field of type "DateInputSize" and pass that variable to the size.

// TS
protected size: DateInputSize = 'small';
 

// HTML
<kendo-datepicker [size]="size" ... />

Open the example in a new window to evaluate it with Axe Core or other accessibility tools.  for the Kendo angular grid

When i do that i see the attached error, which is the same issue i get in our product when running playwright axe

That suggests to me that it is not WCAG 2.2 compliant

Ensure elements with an ARIA role that require child roles contain them

.demo-frame.loaded.demo-module--wrap--718a6 > .demo-module--demoWrap--d1437 > .demo-module--explorerWrap--4bf1f.flex-grow-1 > .demo-module--demoBody--97eee > iframe #k-fbe44131-4768-4755-93c3-e321b714780e

   I have tested kendo grid accessibility with AXE Dev tool. Found following errors that seems difficult to fix.

1)Certain ARIA roles must contain particular children

2)Scrollable region must have keyboard access

Any suggestion to fix these above-mentioned issues could be very helpful. Noticed these issues even exist in kendo grid demos published in kendo documentation. Check the link below

When a tooltip of a dialog is shown and the dialog is closed, the tooltip is still present and is moved into the top left corner.

We use e.g. `kendo-dialog-titlebar` and the close button has a tooltip.

Hi,

if I use both the features locked columns and sticky rows, the sticky rows do not stick in the locked columns.

For me it would be logical if they would stick there too (now the UI looks inconsistent):

Reproduction (forked from your example): https://stackblitz.com/edit/angular-wak7v99i 

Can you please take a look at it?

Hi,

if I change the [placeholder] input on a kendo-editor, the changes are not reflected.

The DrawerAnimation interface isn't exposed in the index file.

DrawerItem, DrawerMode, and DrawerPosition are all exported but DrawerAnimation is missing.

In firefox, open the Kendo Radio Button documentation and slowly resize the window (https://www.telerik.com/kendo-angular-ui/components/inputs/radiobutton)

The radio button will kind of jiggle around and occasionally the white dot in the radio button will become off-center.

This also seems to happen in response to some material bouncy (cubic-bezier) animation transitions.

The directive `kendoGridColumnChooserTool` does not work correctly when having columns which are grouped. See this example: https://stackblitz.com/edit/angular-r9duqpcn?file=src%2Fapp%2Fapp.component.ts

1. It shows that 0 items are selected ("0 Selected items") - This is incorrect because all columns are selected by default. In the example above, I would expect it shows that 4 items are selected.
2. When unselecting an item in the list (popup), it does not actually hide any column.
3. When using directive `kendoGridToolbarTemplate` with `kendo-grid-column-chooser` component, it works as expected. I would expect that `kendoGridColumnChooserTool` directive would work (behave) exactly the same way.

Hello Support,

There is a feature request for this, but I see this as a bug. The Agenda view in the scheduler is advertised to work perfectly on mobile, but I would expect to see the event column one way or another. Now you can only see timeslots, which is not that useful. Can you fix it by making the event column available, maybe as part of the time as text or some other solution.

Ran this on StackBlitz 

import { Component } from '@angular/core';
import {
  LegendLabelsContentArgs,
  SeriesClickEvent,
} from '@progress/kendo-angular-charts';
import { IntlService } from '@progress/kendo-angular-intl';

@Component({
  selector: 'my-app',
  template: `
    <kendo-chart
      (plotAreaClick)="onClick($event)"
      [transitions]="false"
      title="World Population by Broad Age Groups"
    >
      <kendo-chart-legend position="bottom"></kendo-chart-legend>
      <kendo-chart-series>
        <kendo-chart-series-item
          type="donut"
          [data]="pieData"
          field="value"
          categoryField="category"
          explodeField="exploded"
          [labels]="{ visible: true, content: labelContent }"
        >
        </kendo-chart-series-item>
      </kendo-chart-series>
    </kendo-chart>
  `,
})
export class AppComponent {
  public pieData: Array<{
    category: string;
    value: number;
    exploded: boolean;
  }> = [
    { category: '0-14', value: 0.2545, exploded: false },
    { category: '15-24', value: 0.1552, exploded: false },
    { category: '25-54', value: 0.4059, exploded: false },
    { category: '55-64', value: 0.0911, exploded: false },
    { category: '65+', value: 0.0933, exploded: false },
  ];

  constructor(private intl: IntlService) {
    this.labelContent = this.labelContent.bind(this);
  }

  public labelContent(args: LegendLabelsContentArgs): string {
    return `${args.dataItem.category} years old: ${this.intl.formatNumber(
      args.dataItem.value,
      'p2'
    )}`;
  }

  public onClick(event: any): void {
    console.log('Click');
  }
}

When the event is seriesClick, it works as expected, and if I change the type to bar, it works as expected, but when it's as shown as above, the onClick event isn't triggered. 

As I have donuts/pies that might not have data in it, I needed to use plotAreaClick (which I have done for the bar charts)

Thanks,

Add support for Angular's Trusted Types to eliminate CSP compatibility issues and errors when using the Kendo UI for Angular components in applications with strict Trusted Types security policies.

At the moment, the internal logic of the Kendo UI for Angular components uses innerHTML in various scenarios, like placeholder content for virtualization, dynamic rendering of icons and indicators, etc.

Thus, when applications have strict CSP with Trusted Types enabled, developers encounter a "This document requires 'TrustedHTML' assignment" error. 

Although all content set via innerHTML is internally controlled and secure, the Kendo UI for Angular components should work seamlessly in applications with strict CSP and Trusted Types policies without requiring developers to modify their security configuration.

I am using below piece of code inside <kendo-grid>. Here, I am using a dropdown and kendo excel export button inside toolbar. dropdown is in left and button is right aligned. Earlier, it was working till Kendo 18. When I upgraded to kendo 19, it stopped working. 

Root Cause is kendo-dropdownlist contains an array button. When we click on button to expand dropdown, excel export button gets the focus and dropdown loses focus. When we click on dropdown button, 'k-focus' class is applied on 'excel-export'. Because of this, dropdown is not working. 

Code:

<ng-template kendoGridToolbarTemplate>

        <div class="toolbar-container" style="display: flex; align-items: center; gap: 16px; width: 100%;">

            <!-- Dropdown Wrapper -->

            <div style="flex-shrink: 0;">

                <kendo-dropdownlist [data]="data"

                    [(ngModel)]="someField" [valuePrimitive]="true" (valueChange)="perform()"

                    [popupSettings]="{ appendTo: 'component' }" style="width: 175px;">

                </kendo-dropdownlist>

            </div>

            <!-- Spacer to push button to right -->

            <div style="flex-grow: 1;"></div>

            <!-- Excel Export Button -->

            <div style="flex-shrink: 0;">

                <button type="button" kendoGridExcelCommand>Export</button>

            </div>

        </div>

    </ng-template>

If the pane is scrolled, the dark highlight shown when grabbing the splitter is misaligned like this:
