1. Start using the Kendo Tree View in Angular.

2. Load a large dataset for the Kendo Tree View, observe the time taken to render the Tree View.

3. The timing will increase if the dataset keeps on increasing.

4. Suggest some ways to reduce or optimize it.

In some calendar apps like Apple it's nice to extend appointments with a travel time (or preparation time).

Please extend Kendo Scheduler with such an event preparation-time and also a follow-up time, which looks like this:

Using the Editor component with Form Support, if I choose the style Heading 1 and type some letter.

I clean the value using only backspace key on the keyboard and the value of the form control is <h1></h1>.

This is reproductible on the demo : https://www.telerik.com/kendo-angular-ui/components/editor/forms/#toc-template-driven-forms

• Choose Heading 1 style
• Type AAA
• The form value = <h1>AAA</h1>
• Clean the value using backspace
• The form value = <h1></h1>

Expected result

• The form value should be empty

Hi, Kendo team.

We have a small but annoying bug.

In the table filter for numeric column:

• user type first part of floating value quickly - Filter button is still disable
• user type comma symbol
• then Filter button became enabled - comma symbol disappears
• if user type slowly (or very quick) - then is not such bug.

Is it any workaround for it?

Thank you.

Ekaterina.

Hi,

Many users of our apps have asked to add a "Clear" button to the Date Picker popup. For example, it could be placed next to the "Today" button. This would be something very useful and done without too much effort, as there is room in the popup and it doesn't involve any calculation.

Regards,

Augusto.

Hi,

I'd like to request a feature for programmatically dismissing notifications in Angular. This is a common feature for notification / toast component, but it is missing in Kendo UI for Angular.

Right now, once a closable notification is shown, there's no way to dismiss it programmatically, which can lead to clutter (see attached screenshot).

Here are the proposed features:

1. Programmatic Notification Dismissal:

   • Dismiss by type
   • Dismiss by ID
   • Dismiss all

2. Global Notification Limit:

   • Set a global limit for how many notifications can be displayed at once.

These additions would greatly enhance the user experience by preventing notification clutter and providing better control for developers.

Thanks for considering this!

Best, Sergei.

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.

By default the grid pagination only works taking count of the actual records instead of (alternatively) taking in consideration the groups count.

It would be nice to have the possibility to choose between those 2 when using groupBy and process functions.

This pagination feature is already implemented in the Kendo Ui for Asp.Net Core, but it is not available in functions such as process, groupBy or (toDataSourceRequest/toDataSourceRequestString/toOdataString)

Here you can find the related documentation page for the Asp.Net implementation.

Right now the only possible way to achieve this behavior in combo with a KendoAngularGrid is to use the (toDataSourceRequest/toDataSourceRequestString), then into the controller you'll have to mutate the DataSourceRequest Object like following:

[HttpGet]
public async Task<IActionResult> GetData([DataSourceRequest] DataSourceRequest request, CancellationToken cancellationToken) {
    var data = //...  ;

    request. Skip = (request.DataSourceRequest.Page - 1) * request.DataSourceRequest.PageSize;
    request.Take = request.DataSourceRequest.PageSize;
    request.IsExcelExportRequest = true; // without this the items property of the GroupResult type will be null
    request.GroupPaging = true;

    return Ok(await data.ToDataSourceResultAsync(request, cancellationToken);
}

When increasing the browser zoom level while using a kendo-splitter with two kendo-splitter-pane elements, one of the panes exceeds the boundaries of the kendo-splitter. As a result, part of the content becomes hidden.

Steps to Reproduce:

1.  Use a  kendo-splitter with two kendo-splitter-pane elements.
2.  Resize one of the panes
3.  Increase the browser zoom level.

Template:

<kendo-splitter>
  <kendo-splitter-pane [collapsible]="true" size="30%">
    <div>
      <h3>Inner splitter / left pane</h3>
      <p>Resizable and collapsible.</p>
    </div>
  </kendo-splitter-pane>

  <kendo-splitter-pane>
    <div>
      <h3>Inner splitter / center pane</h3>
      <p>Resizable only.</p>
    </div>
  </kendo-splitter-pane>

  <kendo-splitter-pane [collapsible]="true" size="30%">
    <div>
      <h3>Inner splitter / right pane</h3>
      <p>Resizable and collapsible.</p>
    </div>
  </kendo-splitter-pane>
</kendo-splitter>

The page numbers and total items within a pager do not appear to respect the currently loaded i18n locale. For example, there's no comma in the thousands place for the en locale. What makes me believe this is a bug is that the page input which can appear DOES have i18n applied to it so the discrepancy is clearly visible between the two.

As there's no demo with such large page numbers I've created an example as well as a screenshot:
B187rdik (forked) - StackBlitz

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.

Stackblitz example

https://angular-x4rvxqyp-qfq5b7mj.stackblitz.io

Expected Behaviour:

The user should be able to enter a full year 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. This prevents users from entering valid dates, making the input unusable in this scenario.

I couldn’t find an existing bug report related to this issue. Could you confirm whether this has already been reported or provide guidance on a potential fix or workaround?

Thanks
