See https://demos.telerik.com/kendo-ui/menu/scrollable

When you hover over the left or right arrow on the menu, the menu scrolls.

Our client *hates* that, and only wants the menu to scroll when you actually click on the left/right arrow.

Request:

Add an option so that we can turn OFF the scrolling on hover on the left/right scroll buttons in the menu.

We are currently utilizing Telerik's Spreadsheet functionality across two different technologies:

- KendoUI for jQuery: This is being used by our FrontEnd users.
- .NET Assembly of Telerik: This is employed for backend processing and interfaces.

Both Spreadsheet implementations allow us to populate data; however, we've observed a discrepancy between the two. Specifically, there is a misalignment in the available functions, where some functions accessible in KendoUI are not available in the .NET Assembly. To address this inconsistency, we request the following enhancements:

1. Unified Function List: We would like an official list of functions that are consistently supported by both the jQuery library and the .NET assembly. Currently, the frontend offers a broader range of functions than the backend. Since our system relies on both for computations, consistency is crucial.

2. Function Usage Detection: We request an event or function in both the JS and .NET implementations that can detect the functions used within a formula. This will allow us to identify discrepancies early on.

3. Backend Validation: An event that triggers when a formula entered on the frontend is valid there but would fail on the backend due to unsupported functions would be invaluable. This will help prevent issues caused by discrepancies between the frontend and backend function implementations.

4. Enhanced Backend Functionality: We also request additional functions or exposed properties on the backend to perform similar checks as described above. This is particularly important for our customizations that allow formulas to be entered directly on the backend, bypassing the spreadsheet UI.

5. Specific Error Handling: On the backend, it would be helpful to introduce a specific error type, distinct from the generic error, that indicates a calculation failure due to an unsupported function in a formula. Currently, the generic error type could indicate multiple issues, making it difficult to diagnose the root cause.

TreeList with multi-column headers and row filtering throws an error when user tries to reorder a column.

Reproduction of the problem
Open the Dojo - https://dojo.telerik.com/aFIkOPUp/3
Try to move column "position" left or right

Current behavior
Error is thrown 

Uncaught TypeError: Cannot read properties of undefined (reading 'locked')

Expected/desired behavior

Rerdering shall be allowed

Environment

jQuery version: 3.4.1

Kendo UI version: [all]

i've tried to apply autoFitColumn method for treelist accordingly to the documentation, https://docs.telerik.com/kendo-ui/api/javascript/ui/treelist/methods/autofitcolumn#autofitcolumn , and seems it assumes only "simple" columns structure, i.e. no nested headers.

treelist

- has filterable mode 'row',

- some columns are not filterable,

- columns reordering is allowed

drag-n-drop of columns raises error in console

Dear Kendo UI Team,

I am writing to request the implementation of a mention user feature for the Kendo UI TextArea component. This functionality would significantly enhance the user experience and collaboration capabilities of our .NET application.

Similar to popular social media platforms, the ability to mention users within a text area would allow for efficient communication, tagging, and collaboration among users. This feature could be implemented by enabling users to type an '@' symbol followed by a partial username, which would then trigger a dropdown list of matching user suggestions.

By incorporating this feature, Kendo UI would further solidify its position as a leading UI component library, providing developers with the tools to create more engaging and interactive applications.

Thank you for considering this feature request. We look forward to your response.

Sincerely,

Nasif Ishtiaque Islam

There is an issue with the .k-sorted class being applied to the last column in the grid when the actual column is not visible. It also is not updating the k-sorted when a sort is applied after the grid was created. 

This seems to be an issue in the latest release if the column sorted on is hidden, the last column in the grid gets the class. I also noticed that sorting a column does not apply the k-sorted class to the correct column: https://dojo.telerik.com/@dojolee/eFIbaSUn 

Hi,

We have recently upgraded our Kendo MVC version to 2024.2.514.462. The normal upgrade works fine but I was trying to implement the `CSP template` after removing the `unsafe-eval` from the tag as it was announced in 2023 version.

I was following the example given in CSP template and tried changing the template defined in treeview (also as shown in the documentation):-

  sideNavList.kendoTreeView({
      /*template: "<span id='#= item.id #' class='navText'> #= item.text# </span>",*/
      template: ({ items }) => `<span id='kendo.htmlEncode(items.id)' class='navText'> kendo.htmlEncode(items.text) </span>`,
      dataSource: hierarchicalLeftNavData,

It is not throwing error but it's not able to recognize the `item` and rendering the template as:-

<span id="kendo.htmlEncode(items.id)" class="navText"> kendo.htmlEncode(items.text) </span>

Am I missing anything?

I have custom messages for my filter, these values replace the and/or values instead of just the visual after switching the and/or once.

Reproducer: https://dojo.telerik.com/AdOGEQey

When initially running you will see "en/of" (and/or), if you than press any of them the text below will insert the message value of the button rather than the underlaying value of "and/or".

I'm seeing an error in the Chrome console when the filter menu is clicked on in a kendo grid: https://demos.telerik.com/kendo-ui/grid/filter-menu-customization

You can see the example in the link above by opening your console in Chrome and clicking on the filter button. 

Here is the error:

Blocked aria-hidden on a <a> element because the element that just received focus must not be hidden from assistive technology users. Avoid using aria-hidden on a focused element or its ancestor. Consider using the inert attribute instead, which will also prevent focus. For more details, see the aria-hidden section of the WAI-ARIA specification at https://w3c.github.io/aria/#aria-hidden.

Hello, 

- I reproduced my problem on this DOJO https://dojo.telerik.com/EpUVIxek , columns are not on the same position with the category because I have 5 column series and 4 of them are 0 in one category.

The observed appearance is due to the data with zero value for each series. Even if the value for a series/bar is zero still there is a placeholder in the Chart for the respective bar. Hiding the data points with 0 value is not supported in the Kendo UI Chart and I am afraid I could not suggest a possible approach for achieving such an appearance. 

Can something be implemented so the columns with 0 value to not take place?

Best regards.

3. Select the newly created folder and create another subfolder
4. Type "a" or other value that does not match
5. See the arrow disappearing

Current behavior

The expand arrow disappears.

Expected/desired behavior

The arrow should not disappear and the search to work correctly.

I just upgraded from V2021 to V2024. Now, in the grid's filter menu, I have buttons with icons for filter and clear. I don't want the icons. I know I can target them with CSS and do a display: none, but there should be a setting to prevent showing them in the first place. I'm thinking this should be both a global setting for the default and a local setting in the widget to override.

Issue 1:
When I initialize a kendo editor from a div with content, all of the table tools are shown in the editor toolbar (insert row, insert column, etc) on initialization. Once the user clicks in the box they disappear. I prepared a Dojo showing this. 

In the Dojo, you will see there are 2 different editors. The first editor uses a function I wrote that worked in version 2022 but doesn't in version 2024 of Kendo. The second editor is just a default initialization using none of my custom code. The purpose of the first one is to show the toolbar on initialization. In both instances of the editor, you will notice that the insert row, insert column, etc are showing at first and then quickly disappear. This only happens the first time the user clicks into the editor. These should not be visible until the user clicks into the editor and selects a table.

I did notice that if I initialize the div empty, then add the content later programmatically (like this: kendoEditor.value("Hello World");), the issue doesn't happen.

Issue 2: 

Once you add a table, you can't remove it using backspace or delete. Try this example: 

1. In either editor, click the insert table button.
2. Insert a table.
3. Click into the editor and press backspace and/or delete. The table doesn't go away.

I want to set the mask-character in the TimeDurationPicker.

Display as "08:__" or "__:15" is ugly and I want to display this as "08:00" or "00:15"

I am trying to upgrade my Kendo UI JQuery installation from 2022 to 2024 and it is not going smoothly. One issue I'm having is that now my grids with locked columns do not span the whole width of their container. In the old version, the k-grid-table would expand to fill the width of the k-grid-content but now it seems that the columns retain their width, rather than growing like they used to. So now there is a large white space between the last column and the vertical scrollbar. I did notice that if I remove the inline style in the developer tools that is applied to the k-grid-table in the unlocked section, it fixes it. It should continue to expand all columns evenly to fill the available width like it did in versions past or this should be an option that the user can set. To leave that space without any user choice is a bug.

New Version: 

Note, I reported this in a forum post. I know I can write code as a workaround but that is cumbersome, especially when I have many grids and multiple developers working on the project. 

When I incell edit multiple rows I only receive a sync callback through `change` on the datasource for the last row with only that last row in the "changedItems". This results in the grid not removing the dirty indicator for any of the other rows, only the last one is removed. The rows are updated properly and I if I were to manually call grid.refresh() it removes the indicators. If I update the rows individually it has no problems.

Here I've updated only the first row:

Here I've updated only the second row:

Here I've updated the first 2 rows at the same time and only the last one is detected as updated:

Here I've updated the PRS column for all 4 rows to "5" and it saved correctly, but only the last row is detected as updated in the grid:

As there's a lot of code involved I can't just paste it here, I can provide snippets or information about particular settings though.

When a column is set to sticky in a grid and the user clicks edit and then cancel, that column become unsticky for that row only. This happened when I upgraded from 2022 to 2024 so the bug was created somewhere in there. To reproduce, see this dojo: 
https://dojo.telerik.com/@dojolee/evOPeBey

1. Shrink the right side of the screen until it is pretty small (about 700px)
2. Click Run and make sure there is a horizontal scroll. If not, shrink the right and click run again.
3. Scroll and notice that the first column sticks
4. Click edit on the first row
5. Click cancel
6. Scroll and notice that the first row no longer has a sticky column.
