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).

Environment

• Kendo UI version: 2024.4.1112

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.

Bug report

When the Grid is in RTL mode and has horizontal scroll it does not autoscroll when the user try to reorder columns.

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/kmwtfkRd
2. Try to reorder the columns.

Current behavior

The horizotnal scroll does not move when dragging. In non-rtl mode the horizontal scroll autoscrolls while dragging a column.

Expected/desired behavior

The behavior in RTL mdoe should be consistent with non-rtl. The horizontal scroll should move when dragging a column.

Hi team,

I experience a Content Security 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.

Bug report

When there's a DropDownList in the Toolbar's oveflow, clicking to open the DropDownList closes the overflow popup.

Regression introduced with 2023.1.117

Note: As of 2023.1.117, the DropDownList is no longer overflowing, despite overflow: "always". As of 2023.1.425 the DropDownList is again displayed in the overflow, and can no longer be opened.

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.

This is a continuation of the following issue.

There are many properties that can be set during initialization that cannot be changed through the API afterwards.

Take the Kendo UI ToolBar for example. You can add a button to the toolbar and set the text, but you cannot change the text afterwards unless you update the element directly. It may seem like a simple thing to change the text of an element, like so: $("#myButton").text("New Text"). However, if you had set the imageUrl as well, setting the text like I did above would remove the image. Knowing that, you could get the text node and update the nodeValue. That may work today but could easily be broken during a Kendo UI update (for example, if the update included a change that wraps the text in a span).

Having to deal with native elements after they have been created by the Kendo UI components is a dangerous practice for developers as it requires an internal knowledge of how elements are rendered based on the different options set. As mentioned above, it is also dangerous as any update could break our code. Therefore, it is imperative to expose methods that allow us to modify any properties through the API (where possible) to allow us to create clean and easy to maintain code.

If you search the feedback, you will see many requests to add a method here and a method there. There is even a related one to this called "Kendo Mobile: Methods to set properties dynamically".

Suggestion: When you have child elements, such as buttons on the toolbar, please allow us to update those widgets directly rather than through the parent. For example, instead of $("#myToolbar").data("kendoToolBar").enable("#myButton"), allow us to do something like this $("#myButton").data("kendoToolBarItem").enable();

Hi Team,

I would like to request a way to be able to select all child items in a group.  

Thank you!
