Hello,

i'm trying to create a toolbar component wrapper that allows the user to configure the toolbar passing a list of json objects, using overflow feature.

I'm facing 2 problems

when i hide a button using ngIf the button disappears from normal visualization and appears in the overflow popup, despite the available space. The button appears when a resize is fired.
o often get an error "TypeError: Cannot read property 'nativeElement' of undefined" when the overflow popup is opened

Is there a correct way to create buttons dynamically?

Thanks,

My markup

Getting cannot resolve type entity i25.IconsModule error

Hi,

We are using kendo UI for angular in our project. The angular version is 18. We are upgrading bootstrap from version 3.x to five point 5.3.3.
When we did an ng build it failed with the following error.
"cannot resolve type entity i25.IconsModule error"
My question is, are there any changes to the kendo libraries that it needs 
kendo-angular-icons package to be installed as well?
 
We never had to do this before. We never included this library in our angular package.json
 
Regards,
Jyothi

Inconsistent Background Color for Sortable Columns in Kendo Grid (Scrollable vs. Non-Scrollable Modes)

Issue:

Sortable columns in Kendo Grid show inconsistent background color styling between scrollable and non-scrollable modes due to differences in how the DOM is rendered: https://www.telerik.com/kendo-angular-ui/components/grid/scroll-modes#scrollable-mode

Scrollable Mode: Background color is applied to all cells (<th> and <td>) in the sortable column.
Non-Scrollable Mode: Background color is applied only to the header cell (<th>).

Expected Behavior:

The background color should apply uniformly to all cells (<th> and <td>) in sortable columns, regardless of the scrolling mode.

Actual Behavior:

In scrollable grids, the background color is applied to all cells in the sortable column.
In non-scrollable grids, the background color is applied only to the header cell.

Question:

Is there a way to ensure uniform background color styling for all cells (<th> and <td>) in sortable columns, regardless of the scrolling mode, through built-in configuration or a recommended workaround?

Steps to Reproduce:

Create a Kendo Grid with sortable columns.
Enable scrolling for one grid (default behavior) and disable it for another.

Link to Reproduce։ https://stackblitz.com/edit/angular-axcc1j?file=src%2Fapp%2Fapp.component.ts

Environment:

Kendo UI version: ^16.8.0
Angular version: ^18.2.0

How to change the caret icon in DropDownList, ComboBox, NumericTextBox?

Is it possible to customize the black triangular "caret-down" icon used in the DropdownList and similar components (like ComboBox)?

I’d also like to know how to replace the "caret-up" and "caret-down" icons in the NumericTextBox.

Our apps use Font Awesome icons consistently, and I’m trying to replace these default icons with Font Awesome equivalents, but I haven’t been able to figure out how to do this. Could you provide guidance or examples?

Cannot find how to work with Ids for Text box to get Selenium tests to correctly interact with them.

5:45 PM found this SO post: Selenium with Kendo UI

Is the 'hard way' of writing xpath in C# the way to do this, using Se Web Driver? The post is 6 years old ... there's not a better way?

Crossing my fingers, there's an easier way than running the test, letting it fail, mapping out x-path, rinse-lather-repeat, eventually get there? :)

==================== Above New info as of 5:45 20 Nov =====================

Looking over the docs, I find nothing helpful with learning how to make the kendo textbox interactive with Se Tests.

Here is what I'm facing, I'm inserting from some emails and a Stack O post.

It appears our .scss file is a major player here. There isn’t a clear input for the Se tests to see where to put what. I don’t know enough about SCSS SASS to be sure but finally tracked down the id being tacked on to the k-input-inner class. From this I sort of catch on to what’s zapping us with using the Se Web Driver and Se IDE tests.

Here is the Id noted: k-d6dd8b3b-9d55-45cb-927c-634d4f11473c. Note how it is prepended to the k-input-inner to render the text. This appears really super nested. I think the test can’t find where to put the text and just puts it an input at the first point in the hierarchy it finds.

See Screenshot_1.png

The green shows where I typed the text in the intended text location. Yellow shows where the test put it – in the validator indicator span, forgive any terminology error there. I’m not seeing the same inner text area as in the top screen shot.

My conclusion is the _inputs.scss file might be the issue. We’re having rendering given 2 different ways depending on whether we run the test or spin the page up in dotnet watch run.

I’m trying to find where in the _inputs.scss file is the starting point, to drill further into the issue. The closest I can find is on line 332:

.k-maskedtextbox {

height: 1.3rem;

input.k-input-inner {

font-size: 12px;

padding: 1px 3px 0px;

}

If this is right, in order to use Se IDE, Web Driver or Grid, we may have to rethink our SCSS strategy. I’d say that’s above my pay grade.

Still, can we take a look at this?

See Screenshot_2.png

My lead got back with me to clarify that while CSS can be used in design in our case it is not, and to look instead into the Kendo docs for how ids are generated and so on.

Well, looking in the docs I see how to set up a basic project and get basic code working. Can't find anything on how to do what I need -- how to make Se tests drive Kendo elements for doing tests.

Using content projection (<ng-content>) in Kendo Grid

I am attempting to standardize a lot of my grids for my application. They all follow the same general set up for filtering, sorting, etc. But each grid might have some specific customizations. Usually this is just customizing the command column to have different command (edit button, actions menu, etc), but this can also take the form of additional toolbar buttons and the like.

To do this, I am trying to make a component that uses Kendo Grid, has it set up the way I want to, but uses <ng-content> to project additional requirements.

However, it seems this is completely ignored by the grid, and nothing is ever rendered.

Example stackblitz which shows the issue: https://stackblitz.com/edit/angular-zc4drs?file=src%2Fapp%2Fapp.component.ts

The actual kendo grids that I'm working on are much more complicated, which is a large motivation for having a common component that I can use and inject additional stuff into as needed. Any help would be appreciated.

Issue with kendodaterangestartinput and kendodaterangeendinput Attributes Not

I am experiencing an issue with the Kendo DateRange functionality in my Angular project. I am dynamically assigning the kendodaterangestartinput and kendodaterangeendinput attributes using a directive. While the attributes are correctly applied to the <kendo-dateinput> elements (verified in the DOM), the calendar is not showing when interacting with the input fields.

Here’s the directive I am using to dynamically assign the attributes

import { Directive, Input, Renderer2, ElementRef, OnInit } from '@angular/core';

@Directive({
  selector: '[dynamicDateRange]',
  standalone: true
})
export class DynamicDateRangeDirective implements OnInit {
  @Input() dynamicDateRange: 'start' | 'end' | null = null;

  constructor(private renderer: Renderer2, private el: ElementRef) {}

  ngOnInit(): void {
    if (this.dynamicDateRange === 'start') {
      this.renderer.setAttribute(this.el.nativeElement, 'kendodaterangestartinput', '');
      this.renderer.removeAttribute(this.el.nativeElement, 'kendodaterangeendinput');
    } else if (this.dynamicDateRange === 'end') {
      this.renderer.setAttribute(this.el.nativeElement, 'kendodaterangeendinput', '');
      this.renderer.removeAttribute(this.el.nativeElement, 'kendodaterangestartinput');
    } else {
      this.renderer.removeAttribute(this.el.nativeElement, 'kendodaterangestartinput');
      this.renderer.removeAttribute(this.el.nativeElement, 'kendodaterangeendinput');
    }
  }
}

Here’s how I wrote the story component

<kendo-formfield [showHints]="showHints" [showErrors]="showErrors" [orientation]="orientation">
  <kendo-label [text]="label" [for]="dateinput" [hidden]="!showLabel"></kendo-label>
  <kendo-dateinput
    #dateinput
    [formControl]="control"
    [allowCaretMode]="allowCaretMode!"
    [autoCorrectParts]="autoCorrectParts"
    [autoFill]="autoFill"
    [autoSwitchKeys]="autoSwitchKeys"
    [autoSwitchParts]="autoSwitchParts"
    [clearButton]="clearButton"
    [disabled]="disabled"
    [enableMouseWheel]="enableMouseWheel"
    [fillMode]="fillMode"
    [format]="format"

    [inputAttributes]="inputAttributes!"
    [max]="max"
    [min]="min"
    [placeholder]="placeholder"
    [rangeValidation]="rangeValidation"
    [readonly]="readonly"
    [rounded]="rounded"
    [size]="size"
    [steps]="steps"
    [tabindex]="tabindex"
    [dynamicDateRange]="dateRangeType"
    [title]="title"
    [twoDigitYearMax]="twoDigitYearMax"
    [value]="value"
    (blur)="blur.emit($event)"
    (valueChange)="valueChange.emit($event)"
    (focus)="focus.emit($event)">
  </kendo-dateinput>
  <kendo-formhint [align]="hintAlign">
    <ng-content select="[hint]"></ng-content>
  </kendo-formhint>
  <kendo-formerror [align]="errorAlign">
    <ng-content select="[error]"></ng-content>
  </kendo-formerror>
</kendo-formfield>

Here’s how I use it in the template:

<kendo-daterange id="feed-filter-date-range" class="k-mt-4 k-justify-content-between">
  <mnp-date-input 
    label="start" 
    [dynamicDateRange]="'start'" 
    [control]="fromDate">
  </mnp-date-input>
  <div>
    <kendo-formfield>
      <mnp-label text="End" class="k-d-flex k-flex-col"></mnp-label>
      <kendo-dateinput 
        formControlName="toDate" 
        kendodaterangeendinput>
      </kendo-dateinput>
    </kendo-formfield>
  </div>
</kendo-daterange>

Despite the attributes being added dynamically, the calendar does not appear when interacting with the kendodaterangestartinput or kendodaterangeendinput fields. However, when I used the <kendo-dateinput> directly the attributes directly in the template, the calendar works as expected.

<kendo-daterange>
  <kendo-dateinput 
    formControlName="fromDate" 
    kendodaterangestartinput>
  </kendo-dateinput>
  <kendo-dateinput 
    formControlName="toDate" 
    kendodaterangeendinput>
  </kendo-dateinput>
</kendo-daterange>

[Angular] Disable changing value of kendo elements using arrow up/down keys on numeric textbox and datetime input

Hello,

I am trying to implement a directive to prevent changing the values on the client side when an input is disabled. It works perfectly on a native HTML element, but not completely when used on a Kendo UI element such as datetime picker or numeric textbox.

  @HostListener('keydown', ['$event'])
  onKeydown(event: KeyboardEvent): void {
    if (this.appCustomDisabled) {
      // Prevent arrow keys (Up/Down) from changing the value
      if (event.key === 'ArrowUp' || event.key === 'ArrowDown') {
        event.preventDefault();
        event.stopImmediatePropagation();
      }

      // Prevent any other key presses or changes
      event.preventDefault();
      event.stopImmediatePropagation();
    }
  }

  @HostListener('input', ['$event'])
  onInput(event: Event): void {
    if (this.appCustomDisabled) {
      event.preventDefault();  // Prevent any changes to the input
      event.stopImmediatePropagation();
    }
  }

  @HostListener('wheel', ['$event'])
  onWheel(event: WheelEvent): void {
    if (this.appCustomDisabled) {
      event.preventDefault();  // Prevent the mouse wheel action
      event.stopImmediatePropagation();
    }
  }

mouse wheel and key inputs are successfully prevented, but arrow up/down keys are still changing the value. How do I prevent them from changing the value?

My main goal is to prevent the user as much as possible from modifying the value of a disabled input because the disabled=true approach can be easily bypassed from the devtools.
