Bug report

When a card in the TaskBoard is moved if the server returns an error the move could not be prevented. Thus, the card is rendered in the new position.

Reproduction of the problem

1. Open the examples:

• https://dojo.telerik.com/KniulaAd
• https://dojo.telerik.com/iGcbJlWz

2. Move a card to a different column.

Current behavior

Although the server returns an error the card is moved to the new column.

Expected/desired behavior

Moving the card should be prevented when there is an error.

Environment

• Kendo UI version: 2024.3.1015
• Browser: [all ]

Bug report

The addCard command, called from a TaskBoard in the PreviewPane, is also executing for the parent TaskBoard. That results in a JS error.

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/@martin.tabakov@progress.com/ayUsOwel/6
2. Open the Preview Pane.
3. Try adding a Card in the TaskBoard in the Preview Pane.

Current behavior

A JS error is thrown and a card is not created.

Expected/desired behavior

No JS errors should be thrown and the card should be created.

Environment

• Kendo UI version: 2021.2.616
• Browser: [all]

Bug report

Reordering in the same column is not working correctly

Reproduction of the problem

1. Open the Demos - https://demos.telerik.com/kendo-ui/taskboard/remote-data-binding
2. In the first column, move "Campaigns" below "Customer Research."
3. Check the Network tab of your browser, and no update is sent. The "Campaigns" is moved back to the top. Sometimes an update is sent but it contains the wrong index, so the item is still on top.

Current behavior

The task order remains the same

Expected/desired behavior

IT should be possible to reorder the tasks in the same column

The issue is a regression starting with 2025.2.520 version

Environment

• Kendo UI version: 2025.4.1111

2. Configure the built-in Validator options.

3. Specify the validation rules for the fields.

4. The fields are not validated when the task is edited.

A Dojo sample for reproduction: https://dojo.telerik.com/iSamumEw/4
