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,

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.

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.

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 DrawerAnimation interface isn't exposed in the index file.

DrawerItemDrawerMode, and DrawerPosition are all exported but DrawerAnimation is missing.

Hi,

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

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

Can you please take a look at it?

Best regards,
Michael

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?

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.

   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

You're docs say

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

more information Link opens in a new window

Element Location:

.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
<div role="grid" kendodragtargetcontainer="" kendodroptargetcontainer="" mode="manual" class="k-grid-aria-root" id="k-fbe44131-4768-4755-93c3-e321b714780e" aria-label="Data table" aria-rowcount="62" aria-colcount="5">

To solve this problem, you need to fix the following:

Element has children which are not allowed: div[tabindex]

Related Node

<div tabindex="-1" class="k-grid-content k-virtual-content">

Hi,

When the first day of the week is changed dynamically through a custom IntlService, the Calendar weekday headers are updated, but the date cells are not repositioned. (The first day is changed as described in your guide: https://www.telerik.com/kendo-angular-ui/components/knowledge-base/calendar-first-day )

Reproduction (forked from your example): https://stackblitz.com/edit/angular-tqvypgwg
Click on "Set first day to Monday ": the weekday headers are updated to start with Monday, but the date cells remain in their previous positions.

Best regards,
Michael

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.

Works:

// TS

protected size: DateInputSize = 'small';

// HTML

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

When dateinput format is "d/M/y" and "allowCaretMode" is enabled, users are unable to enter valid dates. Tested with dateinput and datepicker components.

Steps to reproduce

  1. Setup a kendo-dateinput component with "allowCaretMode" set to "true" and the "format" set to "d/M/y" (see stackblitz below).
  2. Enter a valid single-digit day and valid single-digit month into the input.
  3. Try typing a year.
  4. Observe that only one character of the year can be entered and the input locks up, preventing the user from completing a valid date.
  5. Try typing a double digit month.
  6. Observe that only one character of the month can be entered and the input locks up.
  7. Try typing a double digit day.
  8. Observe that only one character of the day can be entered and the input locks up.

Stackblitz example - angular v22 + kendo v24

https://stackblitz.com/edit/angular-kendo-dateinput-bug-rdocwtvr

Expected Behaviour:

The user should be able to enter a full year, month, and day after typing a valid single-digit day and month.

Observed Behaviour:

After entering a single-digit day and month, the input locks up, preventing the user from typing more than one character for the year or month. This prevents users from entering valid dates, making the input unusable in this scenario.

Thanks
