Allow customization of the Validation Tooltip position.

For example, positioning the Tooltip based on the cell, on the input.

Hi,

I seem to have unearthed a bug in the Kendo spreadsheet control. When the spreadsheet has only 1 row and there is column validation somewhere on the sheet, if I then edit a cell (without validation), 8 rows are created.

See the following Dojo

Kendo UI Snippet | Kendo UI Dojo (telerik.com)

Steps to reproduce.

1. Run the Dojo

2. Edit the UnitPrice cell to, say 20

3. Save changes

4. Observe in the browser console (F12) 8 rows created.

Expected results are 0 rows created and 1 updated

Thanks

Ian

Bug report

In an Scheduler edit popup that has a required MultiSelect, the validation message disappears after blurring the widget.

Regression introduced with 2020 R2

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/ufAmewEP/11
2. Create or edit a task
3. Remove the item in the MultiSelect and blur

Current behavior

The validation message disappears

Expected/desired behavior

The validation message should remain

Environment

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

### 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.

### Environment

* **Kendo UI version: 2025.2.702
* **jQuery version: 3.7.1
* **Browser: [all]
