Bug report

The row reordering functionality does not work correctly when the draggable column has a small width.

Reproduction of the problem

https://dojo.telerik.com/@user192/ipOyacoH

Open the Dojo and try to reorder a row. The icon inside the hint will keep changing and in some cases you won't be able to drop the row to the expected position.

If you move the hint a bit to the right(towards the next column) this behavior disappears.

Current behavior

The reorder hint shimmers and in some cases does not allow for reordering. This occurs when the column width is small(30px in the example).

Expected/desired behavior

Reorder should work as expected, regardless of the column width.

Environment

• Kendo UI version: 2022.2.621
• jQuery version: 1.12.4
• Browser: [all]

Bug report

When the selectable option is set to "multiple cell" and the user tries to select the content of a single column, the content of the entire row is selected.

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/@NeliK/AzirANuT
2. Try to select the text in the France cell and drag down to select only the content in the ShipCountry column.

Current behavior

The content of the other columns is selected as well - https://somup.com/cZeXIvpRzk

Expected/desired behavior

The behavior is expected when the allowPaste option is enabled. However, once the allowPaste option is disabled only the content of the selected column should be selected.

Workaround

kendo.ui.Selectable.fn._allowPreventDefault = () => true;

Bug report

Grid's Toolbar Columns Menu breaks after setOptions()

Reproduction of the problem

1. Go to and run this Dojo that combines the Toolbar Columns Menu demo and the Persist State demo: https://dojo.telerik.com/hVgwgCdr
2. Click "Save State" so you have some state data to restore later.
3. Click the Toolbar Columns Menu, uncheck "Contact Title", and click "Apply" to hide the column. The column gets hidden without a problem.
4. Click "Load State" to restore the previous state data. The column is displayed again and things are fine.
5. Click the Toolbar Columns Menu, uncheck "Company Name" and "Country", and click "Apply" to hide these columns.
6. Observe only one of these two columns was hidden and the Toolbar Columns Menu remains visible.
Open the Developer Tools, check the Console tab, and observe the error logged: "Uncaught TypeError: Cannot read properties of null (reading 'columns')"
It appears the columns menu's "this.owner" gets set to null at some point in the process of calling setOptions() and never gets set back to a reference of the grid.

Bug Report

When a navigatable Kendo UI Grid is configured with a stacked dataLayoutMode and is in an inline edit mode, using the arrow keys fails to operate as expected for the editor.

Reproducible

1. Go to this Progress Kendo UI Dojo.
2. Edit any line and get into text field or numeric field.
3. Use the arrow keys to edit the component, such as up/down for numeric change or left/right to move cursor in textbox

Current Behavior

The left and right arrow keys do not appear to function. The up and down arrows move to the next rows.

Consider the following scenario: There is a sortable Kendo-UI grid with a corresponding dataSource. Initially, the dataSource contains some items. When updating the dataSource to an empty array, all items disappear from the grid - so far, so good. However, if a column header is clicked afterwards to sort that column, the removed data reappears again.

We created a small "walkthrough" in this DOJO to demonstrate the issue.

FYI: The issue can be avoided by using a custom implementation of dataSource.transport.read which always returns the latest data.
