Bug report

When there are multiple Forms on the same page, submiting one of the Forms triggers the other Forms validation.

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/rkDeetHu
2. Click the 'Submit' button on the second Form.

Current behavior

The first Form is also validated and the field is marked as invalid.

Expected/desired behavior

Only the Form which button has been clicked have to be validated.

The issue is a regression starting with 2025.1.211 version

Environment

• Kendo UI version: 2025.1.211
• Browser: [all]

Enhancement

Expose a clearButton API configuration that will remove or add the clear button from the Form

Overview

Currently, in order to omit the Clear Button from the Form, a programmatical or styling approach should be embarked. However, based on demand, client would find it more intuitive if this operation can be performed through a built-in configuration.

E.g:

<script>
    $("#myForm").kendoForm({
        formData: {
            ID: 1,
            Name: "Ivan",
            Address: "Sofia"
        },
        clearButton: false,
    });
</script>

Bug report

An error is thrown when you try to clear a Form with an Upload or any other widget that does not have a "value" method.

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/@martin.tabakov@progress.com/OWOPiteD/3.
2. Hit the clear button.

Workaround: https://dojo.telerik.com/@iankodj/oLAKiCuK/2

Current behavior

An error is thrown when you hit the clear button.

Expected/desired behavior

No error should be thrown when the clear button is hit.

Environment

• Kendo UI version: 2021.3.914
• Browser: [all]

Please support the plain TextBox as a valid editor within form configuration.  There are times when I would like to put a number into a plain textbox and apply custom code to that rather than use a NumericTextBox.

EG:

{ field: "uploaded", label: "A Label", validation: { required: true }, colSpan: 3, editor: "TextBox" }

Bug report

2. Click on one of the two buttons and fill the form that appears in the Window
3. Open the browser's network tab and submit the form.
4. Multiple requests with the form's data are sent to the controller

Current behavior

Once submitted, the form's data is sent multiple times to the backend

Environment

• Kendo UI version: 2020.2.513
• jQuery version: x.y

Please document an example of editor as a function.

A simple example could be a password field: https://dojo.telerik.com/@GaloisGirl/ARIGOmUj

Reproduction

1. Run sample at https://dojo.telerik.com/@GaloisGirl/eConozaR
2. Click "validate"

Expected result:

1. Validation result should be displayed  as a boolean

Actual result:

1. Undefined is displayed

Fix:

Just add return before "validator.validate();" in method "validate".
