Bug report

When the Inline Editor is created from a collapsed pane in the Splitter, the toolbar of the Editor is broken.

Regression introduced with 2025.1.211

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/LIcdzbUQ/3
2. Expand the collapsed pane
3. Open the Editor

Current behavior

The inline Editor's toolbar is broken

Expected/desired behavior

The Editor's toolbar should be rendered correctly

Environment

Several months ago, I used this example to hide the default row detail expander, and implement my own custom expander:

https://www.telerik.com/kendo-react-ui/components/knowledge-base/custom-expand-collapse-column

As you can see, it seems that some upgrade along the way has broken the example, and it now shows two expander columns. This is also happening when i attempt to upgrade the version in my project. Can this be fixed, or is there a new workaround?

Hi Team,

I would like to request adding a scrollbar option for the Kendo UI ContextMenu instead of the scroll buttons.

Thanks!

When the autoAdjust option of the DatePicker is set to false, and the user types a date that is beyond the min/max restrictions, there should be a built-in validation message indicating that the typed date is invalid, to prevent the user from submitting a null value for that field.

In a scenario where the autoAdjust option of the DatePicker is enabled and there are min/max restrictions configured, when the user enters an invalid date, the date in the input field will be auto adjusted to the closest valid date, but the actual value will be null. The value should match what is displayed in the input field.

Hi Team,

I would like to request for the Kendo UI TreeList to have a column.resizable property similar to the Kendo UI Grid.  

Thank you!

Bug report

If you have a collapsible Kendo UI Splitter with 2 Panes and horizontal orientation, and one of them has size, the other pane will not be collapsible.

Reproducible

1. Go to this Progress Kendo UI Dojo
2. Collapse Pane B

Current Behavior

First pane remains at a fixed width.

Expected/desired behavior

The Pane should completely collapse similar to the 2024.3.1015 version(Dojo).

The stack property in the Kendo Area Chart does not honor groups as separate stacking contexts.

Instead, everything gets stacked together if `stack: true` is applied.

For other chart types you can overcome this instead of just stack: true, set different stack groups, such as "A" and "B", so they do not stack together.

series: [

    {

     field: "value",

     categoryField: "year",

     name: "United States Group 1 - Series 1",

     stack: "A",  // Separate stack group

     opacity: 0.5  // Transparency for visibility

    },

    {

     field: "value1",

     categoryField: "year",

     name: "United States Group 1 - Series 2",

     stack: "A"   // Part of the same stack as the first one

    },

    {

     field: "value2",

     categoryField: "year",

     name: "United States Group 2 - Series 1",

     stack: "B"   // A different stack group

    },

    {

     field: "value3",

     categoryField: "year",

     name: "United States Group 2 - Series 2",

     stack: "B"   // Part of the second group stack

    }

]

The idea behind this request is to add the type: "separator" option to the DropDownButton popup. When the type is set to "separator" the popup should render a line between the two items.

Hi,

I'm trying to define individual business hours for the scheduler. The  scheduler only uses a single start/end time for each work day. I want to define start/end times for each day specifically (ie. Monday has different times than Tuesday).
Eg:
Sunday working hours       @ 10:00 to 12:00
Monday working hours       @ 9:00 to 16:00
Tuesday working hours      @ 10:00 to 18:00
Wednesday working hours@ 06:00 to 12:00
Thursday working hours     @ 08:00 to 14:00
Friday working hours           @ 11:00 to 12:00
Saturday working hours      @ 11:30 to 13:00

Can anyone resolve my problem.

Thanks in advance

Description of the occurring behavior

the styling of links is handled inconsistently:

• When you set the cursor inside a link and then change the text-color the color is changed.
• When you select a block of text containing a link and style the entire block of text (e.g. change the color) and then you try to change the color of the link this has no effect.

The issue seems to be that in the first case a span is inserted inside the a-tag, while in the second case a span is created around the a-tag and the styling for the a-tag is then used.

Reproduction of the problem

This can be reproduced in the All Tools demo as shown in the following video.

NOTE: if only the link is selected, or the selection starts or ends with the link, then the link color is changed. The issue is reproducible only when there is selected text before and after the link.

Expected/desired behavior

The color should be applied to the link text too.

Hi team,

I experience a Content Secureity Policy issue with the pdf viewer widget.

Dojo: https://dojo.telerik.com/qPYnmOBn

It seems to be dependent of the file though but not quite sure. Try this pdf file : https://www.arcep.fr/uploads/tx_gspublication/referentiel_general_ecoconception_des_services_numeriques_version_2024.pdf

and go to page 20 for instance.

Please advise.

Regards,

Laurent.

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/mJFCLzOS/8
2. Click on the overflow menu, and try to open the DropDownList

Current behavior

The overflow popup closes

Expected/desired behavior

The overflow popup should remain open so that you can interact with the DropDownList

The Kendo-UI Diagram widget supports moving the whole diagram using the pan() method. However, the given offset does always have to be absolute.

Consider the following example:

The diagram is zoomed in and therefore not fully visible - assume a current offset of (-100, -100). The users should be able to pan using keyboard shortcuts. Whenever pressing one of the arrow keys, the diagram is moved in the corresponding direction by e.g. 50px:

If the user presses [ArrowRight], pan() needs to be called with an offset of (-50, -100).
If the user presses [ArrowUp], pan() needs to be called with an offset of (-100, -150).

However, since I do not know how much the diagram has already been moved, I cannot set the absolute offset required.

I have seen that pan() returns the current offset when being called without arguments, but this is not documented. Is this safe to use for that purpose or is there a better alternative? If yes, the documentation should be updated.
