React Hook Form validations are not working with MUI Radiogroup

[jaykeerti]

I am able to validate the input box/Text Field. i am unable to validate RadioGroup is selected or not. Please let me know what mistake i am doing here.

I need a functionality in which no radio buttons are selected and user tries to submit, it will throw an error stating that field is required

Here is my CSB

You never use field.onChange or any other handlers to pass your RadioGroup value to RHF for validation.

@Moshyfawn My use case here is when the user does not select any radio option i want to throw an error saying it is required using the fieldState object.

Here is a working example for TextField. Try to submit the form with an empty TextField. It will throw the validation error
