When a DropDownList is configured with both sticky headers and grouping, the first group header is rendered twice when opening the component - once as the sticky header and once as part of the list.

Currently, there is no built-in way to suppress this duplicate. Achieving the desired appearance requires custom CSS styles, and in cases where virtual scrolling is enabled, custom DOM manipulation of internal elements is needed, which causes side effects and edge cases.

Enhancing the DropDownList with a built-in option for achieving this would allow developers to control this behavior without relying on unsupported workarounds.

Hi,

Please provide a template for the operators of the FilterExressions.

thanks

Ability to customize the fields control of the FilterExressions:

Currently, the (X) close button is always shown and visible. In other words, it is not possible to configure the dialog component to NOT display this icon button. It is actually not just about the icon button, but also the ESC shortcut. It should not be possible to close the dialog when the input is set.

Feature request: Add an input `closable` for the Dialog Component ('kendo-dialog') to be able to turn off the closable behaviour. Example:

```html

  <kendo-dialog [closable]="false"></kendo-dialog>

```

The "closable" is `true` by default, ensuring that it is backwards compatible.

 

Use case: A certain dialog is presented to the user and user must NOT be able to close/ignore the dialog. The user is thus forced to resolve the instructions presented in the dialog and resolve it the intended way.

Hi,

in the ListBoxComponent, there is the concept of custom messages, by which a "noData" message can be set:

A similar concept would be beneficial for the ListView (https://www.telerik.com/kendo-angular-ui/components/listview), so that we can show a message in here as well in case no data is available.

Thanks,

Felix

Sticky rows are a very useful feature when there is a lot of data.
However when there is a lot of data, it is also very common to use virtual scrolling because of performance concerns.
So I think this combination should be supported by the kendo grid.

It would be great if the <kendo-listbox> had the possibility to take in a list of selected values, which causes the matching items to be selected.

Currently, the only option I see is to inject the ListBoxComponent as viewChild, and call .select manually, which is quite cumbersome.

Suggestion:

- additionally to the "textField", provide a "valueField" property

- also add a "selectedValues" property, which takes in an array / signal of value properties, which then are automatically selected, whenever its value changes.

See https://www.telerik.com/kendo-angular-ui/components/listbox/api/listboxcomponent

It would be a good option to have an API that prevents the automatic switch of the calendar to the time picker view when a date is selected by the user.

Due to the internal mechanism by which the Scheduler displays events per day, some events are shrunk without reason, because others are shrunk due to overlap.

In the following screenshot, the Scheduler Event 1 has enough space to occupy the entire column, but is shrunk the same as Event 2 (which is shrunk due to the overlap with Event 3). Internally, each day use column separation logic to distribute the events. Since all three events fall into the same slot, the entire column is divided by 3 and events are distributed among them. Since Event 1 is the first event, it has been shown in the first 1/3. This isn't optimal, as this case proves it.

Here is how Kendo Scheduler behaves compared to Google Calendar in this case





Google Calendar

Please provide a way to disable the months or years when displaying months or years in the Calendar. The disabledDates callback function could be evaluated for these views.

Thank you

This will enhance the PDFViewer usability as the Toolbar provides many built-in features like responsiveness, tool customizations, etc., which will add extra value to the component.

The component is already used internally in the Editor and Spreadsheet.

Provide an option to dynamically remove a PDF file from the PDFViewer (a method, property, or a built-in toolbar tool).

When the PDF is removed, show the default blank page or the custom kendoPdfViewerBlankPageTemplate.

The Angular Grid export only includes PDF and Excel formats. Requesting an enhancement to be able to export to CSV for purposes of opening the data in a text editor other than Excel or to allow for easier upload into other applications.

There are articles that show how to do this but it would be better out of the box from Telerik.

I noticed than you create the feature adaptativeSlotHeight for week view, that´s cool, but in my case, I need that feature for timeline views, please.

Provide the possibility to dynamically change the height of the slots in Month, Multi-Week, and other views. This feature is useful in order to fit the events in the specific slot:

jQuery Scheduler:

Add an optional positionCallback property to PopupSettings.

When using CSS transforms (e.g., transform: scale()) on container elements with dynamic values (CSS variables), the Popup component's positioning calculations don't account for the transformed coordinate space.

While the SCALE injection token exists, it only supports static values set at component initialization and cannot read dynamic CSS variables or respond to runtime changes.

Benefits:

• Enables custom positioning logic without breaking collision detection
• Supports dynamic transforms and CSS variable-based scaling
• Maintains backward compatibility (optional property)
• Eliminates the need for workarounds like MutationObserver
• Applicable to all components that use PopupSettings (DropDownList, ComboBox, MultiSelect, etc.)

 

With the current default behavior of the Splitter, when a user manually drags a Splitter pane to resize it, the component stores the pane's size as an absolute pixel value (i.e., flex-basis is set to a pixel value), and this is by design.

This means the pane does not scale with the browser window, unlike panes that have not been manually resized.

It would be useful if the Splitter could convert the pixel values to percentages on window resize, so that all panes continue to scale proportionally regardless of whether they were manually resized.

Currently, the Chat component does not provide a dedicated template for customizing only the avatar part of the user messages.

It would be great if such a template exists, so that the avatar can be customized as desired - for example, conditionally displaying an image with the avatarUrl or displaying only the initials if an avatarUrl is not present.

Enable event handling for paste, copy, and cut actions in the Spreadsheet. This allows developers to track and customize these interactions, improving user experience and data management.

Similar to Kendo jQuery Spreadsheet widget:

https://docs.telerik.com/kendo-ui/api/javascript/ui/spreadsheet#events

 

Provide built-in option to sort Spreadsheet data.
