Hi Robert,
Thank you for reaching out to us.
We have validated the reported issue, and we would like to
inform you that the error class being added to the TextBox component when
validation fails is the default behavior of the component. This is intended to
visually indicate invalid inputs and enhance user experience during form
validation.
To illustrate this behavior, we have created a sample where
validation is performed upon a button click. You can check out the sample using
the link below:

scenario.

further
