The DropDownList's Keyboard Navigation Docs specify that the arrow keys move the highlight in the dropDownList, while Enter selects the highlighted item.

However, in reality, the arrow keys already select items. Via keyboard, it is not possible to select e.g. the third item in the list without selecting the first and the second item first (by pressing the down arrow).

E.g. the docs for Angular describe a different behavior.

Bug report

When the user enters invalid data in Grid popup edit form and presses 'Enter' the Save button becomes disabled. The button does not get enabled even after entering a valid data.

Reproduction of the problem

1. Open the pop-up editor by clicking "Create" or "Edit" in the Grid in the Dojo linked here - https://dojo.telerik.com/QyVhowiQ.
2. Leave a required field (like "ProductName") empty and click Save.
3. Validation fails, as expected.
4. Notice that the Save button becomes disabled. Enter a valid data in the field.

Current behavior

The Save button becomes disabled after a validation failure and cannot be re-enabled.

Expected/desired behavior

The Save button should remain enabled or re-enable automatically after validation issues are resolved.

### Bug report

The Validator shows a duplicated error message when validating a CheckBox.

### Reproduction of the problem

1) Create a standard HTML form with a checkbox, which has two inputs - a visible one with value="true" and a hidden one with value="false" (this is the generated HTML markup when using <input asp-for="@Model.IsChecked" /> or Telerik UI for ASP.NET Core CheckBox component).

2) Initialize a Kendo UI Validator on the form and create a custom rule for the checkbox editor.

3) Submit the form and review the duplicated error message in the validation summary. The Validator validates both hidden and visible inputs.

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

### Expected/desired behavior

A single error message must be displayed when the checkbox is not checked and the form is submitted.

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.
