We are noticing these characters "â€<" showing up intermittently after updating our kendo-angular dependencies to 15.5.0.
It's not an issue we are able to reproduce every day, and sometimes reloading will fix it, but it will appear at the beginning of kendo window headers, and options in kendo dropdowns. We have not changed anything about our code, nor are we using any special characters ourselves in these locations.

Our angular version is 17.3.12

Is this a known issue? What would the fix be?

Thanks.

This is code:


<kendo-textarea
      placeholder="Write description…"
      resizable="vertical"
      [rows]="2">
</kendo-textarea>

 

and this is output (top button is only for vertical resizing and bottom one resizes both ways):

Hi all.

I'm using kendo-pdfviewer and loading it with a PDF I get from a web service.  The web service takes query parameters and returns a PDF as a Byte[] and I turn that into a base64 string and put that in the viewer.  Basic stuff ;)  Here's the element from my HTML:

        <kendo-pdfviewer style="height: 800px" [data]="pdfSrc" [tools]="pdfViewerTools">
          <app-pdfviewer-messages></app-pdfviewer-messages>
          <ng-template kendoPdfViewerBlankPageTemplate>
            <div class="blank-template">No data</div>
          </ng-template>
        </kendo-pdfviewer>


Now, if i.e. the user has a PDF in the viewer and wants to narrow the data with some extra parameters, and that result returns an empty PDF, I need to remove the previous PDF from the viewer.

I've tried to set [data] to null and undefined but that does not work. Any suggestions ?

Best regards,
Kalli Kaldi

Whenever I use kendo-dropdownbutton, if button contains only icon and not text, even though I set title, ariaLabel or attr.aria-label it will give me issues with jasmine.axe ( link ). I solve this every time by setting title and aria-label in ngAfterViewInit, but is there another way that is more aligned with component?

Edit: Screen reader NVDA also does not announce title/aria-label on button focus, so jasmine.axe complains for a reason.

I have disabled item that I pass in items list. But item is still clickable (which I solved in css by setting pointer-events: none, yet via keyboard navigation it is still getting focus. Also when pressing enter it will not trigger itemClick event, but on enter press dropdown will close.

Hi,

I am using Angular 17 with @progress/kendo-angular-pdf-export v17.2.0. I am facing a specific layout issue during page breaks.

The Issue: When a long text is split across two pages, the overflow content on the second page shifts to the far left, ignoring the column's original offset/padding. However, once that specific text block ends, the subsequent rows return to their correct positions.

Constraints:

  • We must use paperSize="A4" for printing requirements (so paperSize="auto" is not an option).

  • We are using a custom layout with div elements (Bootstrap-like grid: col-sm-4 for labels, col-sm-8 for values).

Questions:

  1. Is there a way to ensure that the split text fragment maintains its horizontal position on the next page?

  2. Has this been addressed in any version later than v17.2.0?

  3. Is there a CSS workaround (like display: table or specific k-pdf-export classes) to prevent this shift for split elements?

Any guidance would be appreciated. Thanks!

Hi, not sure if anyone had similar issue before with this. So I have pagination done on backend side and I fetch options for dropdown 25 by 25. [virtual] is set to virtualizationSettings = { itemHeight: 36, pageSize: 25 }. Options are loaded on scroll and everything works fine functionality wise. But when using NVDA screen reader and navigating through options via arrows, as soon as I hit 26 and below, screen reader reads them as 'blank' or reads totally different option (random one, sometimes one above and sometimes second one in list etc.).

Hi, This is driving me crazy.  My karat icons are not centered:

I've made sure everything is set up properly and have tried targeting that exact class and padding the top via css.  Nothing seems to work.

What could be the issue?

Hello,

I'm trying to get a custom column menu item list using the Angular Grid to work, but it does not seem to be accessible through the keyboard.

See following Stackblitz for a reproduction example: https://stackblitz.com/edit/angular-tzm2tpqt?file=src%2Fapp%2Fapp.component.ts

I navigated to a header column using tab to focus the grid and the arrow keys to select a specific header column, then pressed ALT + Arrow Down to open the column menu. The column menu opens as expected, but the initial menu item is not focussed and I cannot access the menu items using the keyboard. Instead, the grid is still focussed.

Any advice on what might be wrong in this example would very much be appreciated.
