I am currently using the ANDI accessibility tool and have encountered an accessibility issue with the tooltip icons across my application.

The tool reports an "Aria-Hidden Alert" stating: "Element is focusable but has or is contained by [aria-hidden = true]."  The tool also reports as "Keyboard Access Alerts" which states" "Focusable element is not in keyboard tab order; should it be tabbable"?

The HTML for these elements shows aria-hidden = true and focusable = false. I believe the focusable attribute should be set to true.

I have attempted to resolve this using JavaScript to directly removing aria-hidden = true and changing focusable to true.  However, there is no built-in configuration in Kendo UI for ASP.NET MVC to customize these accessibility attributes for tooltip icons therefore it didn't work.

Can you make the icons customizable?

I am including a screenshot of the code.

We use the KendoUI for jQuery framework in the enterprise SaaS application we create. Giving our clients access to their data and being able to provide a mechanism where a client could build out some of their own functionality on our Saas platform (ie accessing the Data, webservices etc) is highly desirable.

Our front end is based on a MicroUI approach, so if the client can vibecode building a new microUI, the UI experience with the other microUI we provide would be seamless. Examples might be: Create a Scheduler view showing all the European Holidays in 2026, or create a grid view populated with all the customers who have not transacted in 2025 and show their linkedin link/profile.

We can easily wrap any vide coded application into our application now using the microUI approach, but what we dont get is the same look and feel, themes and components being used. It is this we are looking to solve.

We are using Telerik ASP.NET MVC along with jQuery. Our requirement is to implement ADA-compliant tooltips. Previously, we were using the title attribute for Kendo controls to display tooltips. However, this approach is not ADA-compliant, as screen readers do not consistently read the title attribute.

We have tooltips for various controls, primarily TextBox and CheckBox, which are rendered via shared .cshtml views. We need an ASP.NET MVC solution to render Kendo controls with tooltips that:

Appear on hover of the control

Are accessible to screen readers

Minimize custom JavaScript logic

Essentially, the goal is to implement accessible tooltips for Kendo controls in a maintainable and standards-compliant way.

Is there another way we can implement this purely through a Kendo control only? For example, is there a Kendo property or configuration that could render the required span with the attribute we need? Since Kendo is supposed to be ADA compliant, ideally we shouldn't need additional custom code for a tooltip that can be read by screen readers. It would be preferable if this could be achieved through a built-in Kendo property or flag during rendering.

The horizontal space between all OrgChart nodes on the same level is one and the same and it is equal to the horizontal space needed to show the child nodes of the parent with most child nodes. It is represented by the red squares on the image below. This results in excessive empty horizontal space between nodes with no child nodes or no visible child nodes.

This may be observed on the following Dojo runner. Currently the OrgChart has empty space between the first level nodes, and also there is empty space after the last node:

Suggested behavior:
There is no empty horizontal space between nodes on the same level - highlighted in yellow on the image above. In the above scenario, there should be no empty space between the first level's second and third node and no space after the third node, which may be observed, when the first node has no expanded child node:

 

 

In the OData v4 transport, batch submit treats a top-level HTTP 200 response as success, even when one or more operations fail. This is due to how the changesets function.

The parseBatchResponse  function, which is called by the success callback belonging to the submit function of your OData v4 transport, as well as further processing in the same success callback. No attempt is made at handling anything other than responses having status codes [200... 299].

Please enhance batch handling so inner change set failures trigger explicit client error handling.

The Kendo UI ColorPicker's contrastTool shows the contrast ratios necessary to reach a certain accessibility level. While the current contrast ratio itself is localized, the thresholds for the AA and AAA levels are not. For languages like German, this means that for the ratio, "," is used as a decimal separator while the thresholds below use ".".

Add grouping option to the TaskBoard - multiple rows showing rows for separate projects/initiatives and cards with related tasks for each one. 

The row idea is seen at https://dhtmlx.com/docs/products/dhtmlxKanban/.

Hi!

I have noticed the following behavior of the Kendo-UI MultiSelect widget (reproducible in this DOJO):

1. focus the button
2. click on the X button of the selected tag in the MultiSelect to remove it

-> the button is still focused

The user has interacted with the MultiSelect, so it should grab the focus. Since the tag is removed, I would have expected the whole widget to be focused instead. At least this is what happens when clicking the "clear" button.

As all grids, the kendo Gantt chart's rows change their color when hovering. However, the background overlaps the border between columns and makes them disappear for the hovered row.

You can reproduce the described behavior by hovering one of the rows in this DOJO.

Bug report

If the ColorPicker tools in the Editor are configured to render a gradient, you cannot type in the HEX/RGB inputs.

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/AWEmUSOS/7
2. Open one of the Color tools.
3. Try to type in the inputs.

Current behavior

The inputs are not selectable and you cannot type in them.

Expected/desired behavior

The inputs should be selectable so that you can type in them.

Bug report

In the Spreadsheet, when users scroll horizontally to columns that are not initially visible, then activate Freeze Panes, the Spreadsheet scrollbar behave incorrectly

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/zYbZtYDR.
2. In the Spreadsheet, scroll horizontally to columns that are not initially visible.
3. Activate Freeze Panes.
4. Attempt to continue horizontal scrolling.

Current behavior

When Freeze Panes is activated after horizontal scrolling:

• The Spreadsheet snaps back to the first (leftmost) column, Column A.
• Horizontal scrolling becomes unusable.
• Users cannot navigate to the right-hand columns until Unfreeze Panes is selected.

Expected/desired behavior

• Activating Freeze Panes should retain the current horizontal scroll position.
• Horizontal navigation should remain fully available across all unfrozen columns.
• Freezing should not disable the internal Spreadsheet scrollbar or shift the viewport.
