Currently, when a Kendo component is initialized in the TreeList template it should be initialized in databound, expand, collapse events.

• As the nodes are refreshed when they are expanded the components will not appear as expected in case they are not reitinitized in the collapse/expand event handlers.
• In addition, a setTimeout is needed to ensure that the needed elements are rendered when a node is expanded or collapsed. Adding the timeout leads to a flickering that is not a good user experience solution.
  The dojo linked here demonstrates such an example - https://dojo.telerik.com/@NeliKondova/eFaFEveD

I would like the behavior to be enhanced in order to allow initializing the Kendo component in the TreeList template without the need to use the setTimeout function and if possible without reinitializing the components in the expand/collapse event handlers.

When the slotByElement method is used for multiple elements this could lead to performance issues in Scheduler.
For example, the difference in the performance can be observed in the Dojo examples linked below when loading the Scheduler and when changing the selected resources:

Dojo with 2023.1.314 - https://dojo.telerik.com/@NeliKondova/UJOcEJoC

Dojo with 2023.1.425 - https://dojo.telerik.com/@NeliKondova/UHisivuC

The issue occurs starting with the 2023 R1 SP1 release and could be due to the following fix - #7260

Hi Team,

I would like to request jQuery 3.7.0 to be supported with Kendo UI for jQuery.  

Thank you! 

Allow using kendo templates in columns.attributes for example

<div id="grid"></div>
<script>
$("#grid").kendoGrid({
  columns: [ {
    field: "name",
    title: "Name",
    attributes: {
      "data-id": "#:data.id#",
      "data-clientid": "#:data.clientId#",
    }
  } ],
  dataSource: [ { id:1, name: "Jane Doe", clientId:"#223" }, { id:2, name: "John Doe", clientId:"#354"  }]
});
</script>

Currently, the Kendo UI Toolbar supports adding icons to items by setting the "icon" property as documented here. However, only Kendo's own icons are supported.

In other widgets (like the Grid), adding custom icons (to a toolbar!) is already possible by specifiying an icon class.

However, if you wanted a third-party icon (or one of your own) directly to a standalone Toolbar, you would need to create a whole new template from scratch or replace the DOM element after rendering or use some hacky approach like demonstrated in this DOJO. While the first one means a lot of work, the latter ones are both not very stable.

Therefore, I propose to extend the icon support for Toolbars in general. I can think of two different solutions:

1. Let the developer specify an icon class (like in the Grid) that is then written into the DOM.
2. Let the developer specify some sort of "content template" that is displayed e.g. in a button or a splitButton. This way any content may be displayed in a toolbar item and this also allows for more complex and customized styling regarding the layout of e.g. icon and text.

Hi Telerik Team,

We are using latest version (2022.1.412) of the Kendo jQuery tool set. The latest version of Kendo jQuery is using one of the older version of jszip 2.6.1, which is being tagged a vulnerable by our scanning tool. Can you please upgrade the version of jszip in your latest Kendo jQuery (KendoUIProfessional and Telerik.UI.for.AspNet.Mvc5)  

Assume there is a Toolbar with a splitButton that has a subItem. Both the splitButton and the subItem have clickHandlers configured. As long as the splitButton is not in the toolbar's overflow, everything is working correctly. However, when overflown, clicking on the subItem executes the clickHandler of the splitButton instead of the clickHandler of the subItem.

This behavior can be reproduced in the following DOJO: https://dojo.telerik.com/enanUKan/3. Watch the console output when clicking the splitButton/its subItem.

Two more hints:

• The bug does not occur when using Kendo UI versions < 2021 R1 SP1 (2021.1.224).
• The bug does not occur when the splitButton has no clickHandler.

Unfortunately, both options are no viable solution for us. Any suggestions?

Currently, it is not possible to navigate between colors in Editor Font and Background ColorPickers with the keyboard.

Reproduction of the problem
1. Go to https://demos.telerik.com/kendo-ui/editor/all-tools
2. Navigate to the Font or BackColor tools in the toolbar
3. Press Down Arrow

Current behavior
The Font/BackColor tools in the toolbar are opened, but it is not possible to navigate inside in order to select a color.

Expected/desired behavior
On pressing down the arrow key the color in the top-left corner of the palette should be focused. Then pressing other arrow keys moves the focus to the desired color. Then:

- Pressing Enter selects the color and applies it to the editor`s content
- Pressing Esc closes the dropdown without selecting a color, focus remains on the ColorPicker button.

•  "Create a Table" tool works only by pressing Alt + Down Arrow and expands a popup. I suggest expanding the popup on Space or Enter as well. Thus the current Alt + Down Arrow behavior could work as well.

•  It is not possible to focus through keyboard the "Table Wizard" tool inside "Create a Table" popup:
  

Reproduction of the problem

1. Go to https://demos.telerik.com/kendo-ui/editor/index
2. Focus Editor
3. Press F10 to focus toolbar
4. Press Tab key until "Create a Table" tool is focused
5. Press Space/Enter to activate it - nothing happens.
6. Press Alt + Down Arrow to expand the popup
7. Press Down Arrow to select table size

Current behavior

It is not possible to select the Table Wizard tool neither through arrow keys nor through Tab

Expected/desired behavior

When the bottom table size cell is reached, pressing Down Arrow once again moves the focus to the Table Wizard tool.
When Table Wizard tool is focused, pressing Up Arrow moves the focus to the bottom table size cell.

Bug report

setOptions throws an error when toggling reorderable on and off

Reproduction of the problem
Dojo: https://dojo.telerik.com/eReWexEL

When the dates for the current view are changed in Scheduler, the screenreaders do not read the new date.

Reproduction of the problem

1. Go to Keyboard Navigation Demo
2. Go to the arrow buttons in the toolbar and click 'Next' to change the date
3. Date changes to "Sunday, June 16, 2013 - ..."

Current behavior
The screenreaders do not inform the user that the date has been changed.

Expected/desired behavior
The user should be informed that the date has been changed.

Environment

Hi Team,

I would like to request the Kendo UI Spreadsheet to include JSZip 3.x functionality for future releases. 

Thank you!

Currently the only way to make column headers fixed and always visible as you scroll through a Kendo Grid is to make the height of the grid fixed. This doesn't allow responsive UI and dynamic sizing of the grid. I would like to see support for having fixed headers regardless of height of the grid, such that the grid may fill whatever container it's in and change size while allowing this.

This Telerik response confirms the current functionality:

Hi Team,

I'd like to request the autoScroll functionality with Keyboard Navigation for the Kendo UI TreeView so if the user navigates below or above the page, the focused item will scroll into view.

Thank you!

Hello

Is it possible to group events by 2 different fields in a different view ?

Like :

Custom View 1 - Grouped by Room

Custom View 2 - Grouped by Attendee

Thank you

Feature Request

It should be possible for the value of the RadioGroup to be set to zero.

Reproduction of the problem

https://dojo.telerik.com/@NeliKondova/ObIXuric

Current behavior

Currently, when the value of the RadioGroup is set to zero, not item is actually selected as a value. The value of the RadioGroup could be set to zero only if it is a string.

Expected/desired behavior

To be possible the value of the RadioGroup to be set to 0.

Environment
Kendo UI version: 2021.1.1118

The color picker right now support only to display the HEX format or RGBA format. The color picker should also support RGB.

Our customer is used to using the RGB format and wants to use that format. The reason we do not want RGBA is that the color picker could use opacity and the selected color will be used in a report so opacity has to be always 1.

We tried to prevent the use of a different opacity but could not find a solution.

The pager feature is a nice addition, but it could be enhanced with the following additional options which would help if there are a lot of pages to scroll through:

• Add an option to move to the next/prior set of pages.  For example, if 10 pages are showing and you are on page 1 it would jump to page 11, page 12 would jump to 22 (and display pages 11 - 20), and so on, or if going backwards 39 would jump to 29 (and display pages 20 - 30), and so on.
• It would be nice to enter a specific page number to jump to and hit Apply or OK to go directly to that page so you don't have to jump through numerous pages you don't care about (especially when there are hundreds or thousands of pages based on the current number of rows showing).  So if I wanted to jump to page 654 pages 651 - 650 would be displayed with 654 selected).
• It would also be nice if there was a way to display the total number of pages (to make the page jump more manageable).  This would require making a call to determine the total number of pages based on the rows in the database and number of rows displayed per page or otherwise updating the value - and not displaying a total if the value returned was null.
