Programmaticaly show error message on field

Hello, Marco,

I can suggest checking and commenting on this issue where we have listed this as one of the improvements:

https://github.com/telerik/kendo-react/issues/438

`Submit remote validations - workaround till feature is available: in this demo + validation debounce`

The issue also contains an example of a possible approach for server validation with the current state of the Form component.

Thanks for the link.
I had already found it, yet the proposed solution is not sufficient for my needs.
I have to show the errors *for each* field of the form.

Is there a place where I can post new feature requests?

In my opinion the Kendo component <Form> should expose a method to set the error of each field, like Formik.

    onSubmit( values, { setSubmitting, setFieldError } )

Many thanks

Hello, Marco,

All feature requests can be posted in our feedback portal:

As we already have a GitHub item for this logged (which is usually the next step after a feature is approved), I can recommend directly commenting inside the issue. The comment can be to describe the request and the use case.

I am currently trying to solve a very similar problem. I have a relatively simple signup form.  While I do plan to do some basic client side validation, the REST endpoint will check all of the input and respond with a 400 status code.
In the respon body, I return the original request body and a collection of errors.

{
"code": "REQUIRED_FIELD",
"message": "Last name is required.",
"keyName": "last"
}

I tried setting the validationMessage, but that didn't work. I decided to try passing the server side error as custom prop "restErrorMessage".  This FieldWrapper code was borrowed from some Kendo sample code.

<FieldWrapper>
<Label id={labelId} editorId={id} editorValid={!showError} editorDisabled={disabled} optional={optional}>{label}</Label>
<div className='k-form-field-wrap'>
<KendoInput
id={id}
placeholder={placeholder}
valid={valid}
validityStyles={showFieldValidation}
disabled={disabled}
ariaLabelledBy={labelId}
ariaDescribedBy={`${hintId} ${errorId}`}
maxLength={maxLength}
{...others}
/>
{showHint && <Hint id={hintId}>{hint}</Hint>}
{showError && <Error id={errorId}>{validationMessage}</Error>}
{showRestError && <Error id={errorId}>{restErrorMessage}</Error>}
</div>
</FieldWrapper>

Once the user types something in the field, I want to hide the error.  We won't know it passed until the form is submitted again.  I feel leaving this there can confuse some users.  This is how I determine that.

const showRestError = !modified && restErrorMessage.

I may hit a roadblock, but this is the road I am traveling.
