Angular 2: Iterate over reactive form controls

Question

I would like to markAsDirty all the controls inside of a FormGroup.

Answer 1

This is what working for me

private markFormGroupTouched(formGroup: FormGroup) {
  Object.keys(formGroup.controls).forEach((key) => {
    const control = formGroup.controls[key];
    control.markAsDirty();
    if ((control instanceof FormGroup)) {
      this.markFormGroupTouched(control);
    }
  });
}
