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.

The migration tool reformats all Angular HTML templates and removes comments. Add an option to suppress these formatting changes. Provide a report of required or proposed migration steps instead of modifying templates directly. Documentation of the formatting rules would also help users understand and manage changes.

Add functionality to the Java Spring Boot sample application to support server-side data operations, such as sorting, filtering, and pagination. Currently, the demo uses the process method to do the operations on the client.

When typing into the Angular Datepicker on iOS devices, the page scrolls unexpectedly after entering the first character of any date part (day, month, year). The scroll occurs on each subsequent character input (2nd, 3rd, etc.), making it difficult to use the input field.

Steps to Reproduce:

  1. Open a webpage with a Kendo UI Datepicker on an iPhone (iOS v16+, any model). Ensure the datepicker is positioned far enough down the page that scrolling is required to reach it. Example can be seen at https://angular-v7j3ag.stackblitz.io/
  2. Focus on the Datepicker input field.
  3. Enter a date manually using the on-screen keyboard.
  4. After typing the first character into any date part, the page behaves normally, but it scrolls up to the top of the page on subsequent character inputs.

Expected Behaviour: The page should remain in place when typing, allowing smooth input without scrolling.

Observed Behaviour: The page scrolls up after entering the second character of any date part (day, month, or year) and continues to do so on each further input.

Reproduction: The issue was recreated using Kendo's own Datepicker example (with added spacing to demonstrate the scroll behaviour). https://stackblitz.com/edit/angular-v7j3ag

Affected Platforms:

  • All iPhone models (tested 11 - 15) with iOS v16+ (reproducible on Safari and Chrome browsers).
  • Does not occur on desktop or Android devices.

Additional Notes:

  • A video demonstrating the behaviour is attached.
  • This has been reproduced on both BrowserStack and physical iPhone devices.

I couldn’t find an existing bug report related to this issue, so I would appreciate it if you could confirm whether this has been reported or provide further guidance.

When virtual is true for a multiselect and checkboxes are set to true, there is a bug which results in multiple items being selected.

To reproduce, one needs to scroll down a long list of items.  The amount to scroll seems random but might have something to do with the itemHeight setting.  When clicking directly inside the checkbox, two items are selected at once - the item selected, and one other seemingly random item.   This does not happen if the click selection event happens inside the item, but not the checkbox.

I have reproduced this inside this code sandbox: https://codesandbox.io/p/sandbox/mystifying-shirley-2qxn32

Dear Kendo-Supportteam,

We are experiencing an issue with the Editor component.

It turns out that setting the iframe input to false causes the paste event to be triggered twice.
Once as documented before the valueChange event and once seemingly as the native paste event after valueChange.

There are multiple issues resulting from this.

  1. Calling preventDefault on the initial event also does NOT prevent the native event from triggering directly after. Only the following events from the Editor itself are prevented.
  2. As the next event is the actual native event of type ClipboardEvent, the interface is different from what the type definitions suggest. Leading to errors, if the attached method tries to just call isDefaultPrevented on the event.

It is quite easy to reproduce this from your event demonstration examples by just setting the iframe input to false and maybe also trying to call isDefaultPrevented in the respective paste event handler.

Kind Regards,
Hannah

Please provide built-in way to set attributes to the internal Input element. These can be HTML attributes like "autocomplete", "aria-describedby" and others, and also custom attributes if such are required.

Currently the only way to set attributes is programmatically, for example through a custom directive:

As demonstrated by the example of the current version and its screenshot, the title of the legend is black when using a dark theme:

Legend - Chart - Kendo UI for Angular (telerik.com)

telerik.com/kendo-angular-ui/components/charts/examples/chart/legend/title/?theme=default-main-dark&themeVersion=7.0.1

The rest of the text is white which leads me to believe that this is a bug. This issue is not present when using a light theme.

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.

When setting the [zoom] value in TypeScript the drop down value does not reflect this and remains at the default of 125% even though the PDF is zoomed in/out.

 

 

Adjusting the zoom level using the buttons then "corrects" the issue and it displays the right value.

The internal element has a calculated width - but it only grows in value if slider width changes (responsive or even in CSS with media queries etc).

It permanently stays at the largest size.

I need an Angular control works pretty much like Kendo-JQuery Autocomplete control or Telerik Asp.Net Auto Complete text box. 

I understand that Kendo-Angular currently have an "auto complete" control based on a dropdown. However, it is missing some core features I am looking for:

1. It needs to accept multiple inputs.

2. It needs to eliminate unmatched results based on user input.

3. It needs to call a server side API to get the available items dynamically after input changes.

The current Kendo-Angular AutoComplete MIGHT have the 3rd point since I have not yet to try with all the events, but I am pretty sure that the first 2 points are not there. If they do exist, please provide demo or documentation link.

 

Thank you.

I upgraded today from 4.3.7 to v11 and the dates are 1 day off in the scheduler month view, meaning the date variable from let-date (I think).  

 

<kendo-scheduler <ng-template kendoSchedulerMonthDaySlotTemplate let-date="date"> ...
<div>
{{ date | kendoDate : 'dd' }}</div>


<kendo-scheduler

    <ng-template kendoSchedulerMonthDaySlotTemplate let-date="date">

                ...  <div>{{ date | kendoDate : 'dd' }}</div> 

 

The date is just flat out wrong. What's weird is the mouseover shows the correct date.

Again, if I use the old version everything works as expected but the v11 update I'm off by one.
