In the Kendo for Angular Splitter component, adding or removing items from the bound array causes all panes to re-render, even if only one pane is affected. This results in unnecessary content reloads—for example, iframes inside panes are forced to reload, disrupting the user experience.
This behavior appears to stem from change detection triggering full DOM updates within the Splitter. We propose optimizing the component to prevent unnecessary re-renders of unchanged panes, improving performance, and preserving pane content during dynamic updates (similar to version 6.3.0).
Example with CSS that visually demonstrates the re-rendering of content - https://stackblitz.com/edit/angular-p7g2g477-8buqmjpe

It would be nice to have a feature to remove some operator from the grid filter built-in functionality as a global setting so that they apply across all grid columns without needing to repeat this customization for each column.
I understand that Kendo supports this functionality as described, but my expectation is to configure it as a global setting rather than on an individual basis. This would significantly simplify configuration in cases where multiple grids or columns are involved.
We would like to provide the same loading behaviour to our customers by displaying a custom loading spinner.
Therefore I request the feature for a "Angular TreeList Loading Template", like it is already available for kendoGrid.
Currently, when the Timeline has a horizontal orientation configured, only one event at a time can display its details - the selected one.
It would be great if multiple events could be visible at once in horizontal orientation as well similar to the rendering of the vertical orientation of the Timeline.
Hi, Team!
I would like to request the possibility of inserting various shapes in the Editor component similar to the functionality in Microsoft Word.
Here is a possible workaround: https://stackblitz.com/edit/angular-lx34zzvp-qhvevap1
Hi, Team!
I would like to request a functionality that allows the developer to bind the Signature component to a custom string value similar to:
We could really do with a file explorer, I believe this is already available in your JQuery suite and is planned for .NET Core.
Syncfusion have already implemented an angular file manager which can use Azure Blob Storage as a backend (though other backends are also available).
In fact the syncfusion file explorer is based on your own component. After some digging around looking for a similar solution I found their design document for the component which directly refers to the Telerik's own components. You may want to consider contacting syncfusion on this because it appears to me that they may have breached your copyright.
The FileManger Widget in Kendo for JQuery is a component which is extremely useful in lots of use cases. However, there is not such a component in Kendo for Angular - and adding JQuery to a new Angular app doesn't seem to be the way to go in 2025.
Therefore I'd like to suggest adding a FileManager component to Kendo for Angular- I would be willing to pay extra for that, btw ;-)
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:
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:
Additional Notes:
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.
Hi,
It will be a nice feature to have the ability to customize the drag hint of the built-in row reordering similar to the hintTemplate.
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:

Add a locale formatting option to the Grid pager elements, similar to the functionality available in the DropDownList within the Grid pager.

When rendering a "No records available" message or template, this should be centered, not stuck in the scrollable columns section.
We face some issue with the with keyboard inputs. The current behavior is that the kendo tries to help us the dates right. For example if you have entered the 28th of February and you start to type another new date which should be the 31.12.2019 for example, after typing the first "3" the is immediately jumping to the month after hitting the first number because there is no date in February which has two digits on a day and starts with a "3". So it tries to get the dates right but the user maybe wants to replace the whole date and just want to continue writing the date.
We need a functionality that the not validate the date the way he does it right now, overtake the validation, like turn it off or anything like that?
When trying to render some PDF in the Kendo PDF Viewer it fails to render a number of characters. The characters are from the font "STSong-Light".
The file is also rendered in pdf.js viewer, but it looks like a substitute font is used (is a bit bolder).
Provide an option for the Kendo UI for Angular PDFViewer to load substitute fonts or alternatively, an option for the developer to provide its own collection of fonts.
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:

and Gantt Chart from Syncfusion.
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:
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>
