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?

Best regards,
Michael

If you click the first 2 cells in column "UnitPrice", the first one reports column 2 (which is correct), the second reports column 1.

I suspect rowSpan causes this, rows without rowSpan seem to work.

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 current FilterService does not handle nested composite filter descriptors, ignoring them and only processing individual filter descriptors. This limits functionality, especially for complex filtering scenarios. The request is to enhance FilterService to fully support and process nested composite filter descriptors.

Look at the notes for use cases.

Hi ,

I want the kendoGridFocussable to apply the FocusableDirective on an anchor tag. This should allow the user to reach the anchor element using only the arrow keys without pressing Enter. (Example :

Hello,

When I try to delete all grouping manually by setting an empty group array, datas are disappearing. The grid datas are empty but reappears if I set grouping again. Also I could see data if I scroll down but I can't see any if I haven't enough lines to do so.

In attachment you could find a demo based on the "Collapse All with Grouping" tutorial.

First of all, thank you for providing the state management feature. For me it's one of the most important features of a grid component.

But unfortunately it fails to restore the columns state. This is because each time a grid component and it's columns are instantiated, new IDs are created for the columns. When loading state the columns are identified by their IDs.

When a column is persisted with e.g. id 'k-grid-column-1' and the grid will be destroyed and re-created, then the new column ID is not identical with the old one. Thus restoring the column's state will fail.

Please have a look to this StackBlitz example: https://stackblitz.com/edit/angular-vauqyshn?file=src%2Fapp%2Fapp.component.ts

A possible workaround is to save also the column's field property and later use it to re-map the saved id to the new id.

A better solution may be to extend the GridColumnComponent with something like a "PersistenceKey" property, which will be used for identifying a column. A directive may also work. Otherwise generating non transient unique ids for the grid columns will also work.

Best regards,
Holger

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.

We found a bug in our application on tablet portrait mode when we want to select a date from the filter menu inbuilt feature of Kendo grid. 
When the user wants to select a date, the filter closes up and the user is not able to select any date from the calendar.

The issue is happening on tablet device in portrait mode and we found out that it's happening on your documentation too. To reproduce the issue, please go to the "Angular Grid Filter Menu" in your documentation:
https://www.telerik.com/kendo-angular-ui/components/grid/filtering/filter-menu/

Please open the dev tools and set the browser on any tablet portrait size or use Galaxy Tab S4.
In your first example (Angular Grid Filter Menu), please click on the "Date" filter in the grid. When the popup opens up, please click on the calendar icon 
of the date input field. 
When the calendar shows up, try to select any date. You'll see that the filter closes up and the user is not able to select any date. Demo video attached for reference.
Please fix this bug as we support Samsung Galaxy tablet devices and we're using this feature in our project.

Hello,

I tried to implement this new feature : https://www.telerik.com/kendo-angular-ui/components/grid/scroll-modes/virtual#controlling-the-expanded-state-of-all-root-level-groups

You can see in the demo that if you remove all grouping, the content is now limited to 50 lines instead of displaying the whole 1000.

I found a workaround by expanding all before removing the grouping but it is not very user friendly.

If you can patch it ASAP that would be great. 

And thank you to finally have pushed this long awaited feature !

When setting the Checkbox component to disabled while the form is marked as touched, the k-invalid class is applied to the checkbox control.

That's because of the implementation of the isControlInvalid property:

public get isControlInvalid(): boolean {
    return this.control && this.control.touched && !this.control.valid;
}

According to the Angular source code:

    /**
     * A control is `valid` when its `status` is `VALID`.
     *
     * @see {@link AbstractControl.status}
     *
     * @returns True if the control has passed all of its validation tests,
     * false otherwise.
     */
    get valid(): boolean;

So valid() returns false when `status` is DISABLED.

The `isControlInvalid`property should better implemented like this:

public get isControlInvalid(): boolean {
    return this.control && this.control.touched && this.control.invalid;
}

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,

Currently, it is not possible to enter a date that falls exactly on a Daylight Saving time.

Check the following example where it is not possible to enter 3 for the hours' section (it is also not possible to select 3 from the TimePicker popup):

https://stackblitz.com/edit/angular-nstdolh5-xfiws9nr

That behavior is expected as there is no such time in the Bulgarian time zone. Daylight saving time begins on 30 March 2025 03:00 when the time is moved 1 hour forward.

The demonstrated undesired behavior for the specific date will be reproducible only if the example is opened in the specified time zone. But the same behavior is valid for any other date that falls on Daylight Saving time in other time zones.

We should decide on what the expected behavior is for such cases. For example not allowing entering the value, displaying an error, auto-switching to the real hour (4 AM), etc.
