Provide support for dynamic label positions for the Donut chart.

Some labels to be displayed inside the Donut, and other (which couldn't fit) to be outside, similar to:

Kendo's Angular components that have optional inputs are not built correctly.

For example on the `kendo-avatar`component the input `imageSrc` is defined like this:

 @Input() imageSrc: string;

however, since it is an optional input it should be defined like this:

 @Input() imageSrc?: string;
// or
 @Input() imageSrc: string | undefined;

Hi Team,

I would like to request the toolbar data validation tool like this Kendo UI for jQuery demo to be included in the new Angular component. 

Thank you!

We have a scenario where we have inputs inside the sortable component. As the user types into the input the focus is lost constantly this is due to the Sortable component being re-rendered unnecessarily by Angular change detection. You can see an example here

Angular is moving towards immutable data structures and it is often the recommended practice. Therefore I believe the sortable component should be able to handle the scenario provided. This should be achievable by internally using a trackBy function to help Angular recognise when data hasn't changed. This should be accompanied by allow the consumer to provide their own function for tracking.

A similar issue was raised 5 years ago but wasn't adopted. In my opinion given the massive advancements in Angular and the introduction of Signals this becomes a more pressing issue now and arguably moves from the realm of feature request to bug.

Hi,

We've noticed a significant difference in how the "Select All" checkbox functions in the Grid and TreeList when paging is enabled.

Our application uses both components, and users expect them to behave consistently. However, we’ve identified several issues:

1. Inconsistent User Expectations

• In the Grid, "Select All" applies only to the current page.

• In the TreeList, "Select All" applies to all pages, including hidden rows.

• This inconsistency can confuse users who switch between these components, leading to unexpected behavior and frustration.

2. Confusing Bulk Actions

• In the Grid, users understand that selections are limited to the visible page.

• In the TreeList, users might unknowingly select thousands of records, potentially causing unintended bulk updates or performance issues.

3. Risk of Data Loss or Errors

• Users assuming the TreeList behaves like the Grid might:

  • Select all rows, perform an action (e.g., delete or update), and unintentionally affect all pages instead of just the current one.

  • This can lead to accidental data loss or incorrect modifications.

We need a consistent approach to "Select All" behavior across both components to prevent confusion, errors, and performance issues.

Expected behavior

If "Select All" is checked, it should:

• Select all visible rows on the current page.
• Select all children of selected parents, even if those children are on other pages.
• Maintain selection when navigating to another page.

If it should be submitted as a bug, please let me know.

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

Currently, the kendoRippleContainer directive takes effect only on the following elements - buttons, checkboxes, and radio buttons:

• https://www.telerik.com/kendo-angular-ui/components/ripple/api/ripplecontainerdirective

It would be great to have the ability to apply the Ripple to other various elements as well.

Provide a built-in feature to collapse or expand child columns of the group column similar to ag-grid.

Workaround using the header template: https://stackblitz.com/edit/angular-orwl7wza

I'd like to report that my issue linked in Duplicated item was not fixed: 

Closed bug: https://feedback.telerik.com/kendo-angular-ui/1484071-scheduler-event-editor-recurrence-editor

My bug marked as duplicate: https://feedback.telerik.com/kendo-angular-ui/1657303-scheduler-some-events-are-incorrectly-duplicated-despite-the-rules-written-on-them

It can still be reproduced in new version 17.3.12 

https://stackblitz.com/edit/angular-pusn73-en4gpcjt?file=src%2Fapp%2Fapp.component.ts

The event with recurreneRule that suggests that this event appears on each Tuesday till 20201014 is visible on Wednesday 14th.

Currently, it is not possible to enter a date that falls exactly on a Daylight Saving time.

Check the following example where it is not possible to enter 3 for the hours' section (it is also not possible to select 3 from the TimePicker popup):

https://stackblitz.com/edit/angular-nstdolh5-xfiws9nr

That behavior is expected as there is no such time in the Bulgarian time zone. Daylight saving time begins on 30 March 2025 03:00 when the time is moved 1 hour forward.

The demonstrated undesired behavior for the specific date will be reproducible only if the example is opened in the specified time zone. But the same behavior is valid for any other date that falls on Daylight Saving time in other time zones.

We should decide on what the expected behavior is for such cases. For example not allowing entering the value, displaying an error, auto-switching to the real hour (4 AM), etc.

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.

Hi,

It would be a good addition to the Gantt component if a progress completion indicator is rendered on the tasks as in Kendo UI for jQuery.

Provide the ability to change a task duration by dragging and dropping it at the required position. 

Similar to the Kendo jQuery Gantt:

https://demos.telerik.com/kendo-ui/gantt/index

and Gantt Chart from Syncfusion.

It will be a good addition to the chart types if the Marimekko Chart was introduced. This chart type is useful for visualizing categorical data distributions with variable column widths.

Implementing a Lollipop Chart type would improve data representation. This chart type enhances readability by combining a dot and a line to emphasize data points, making comparisons clearer.

https://datavizproject.com/data-type/lollipop-chart/

The introduction of an Alluvial Diagram chart type would be beneficial. This type of chart helps visualize changes in categorical data over different stages, supporting insights into process flows and transitions.

The introduction of an Alluvial Diagram chart type would be beneficial. This type of chart helps visualize changes in categorical data over different stages, supporting insights into process flows and transitions.

Adding a Parallel Sets chart type would enhance data visualization capabilities. This type of chart effectively displays categorical data flows and relationships, making it useful for comparative analysis.

Hi, Team!

I would like to request the introduction of designated properties for the Gantt that allow me to specify the progress start and end for each individual task.

Thanks in advance!
