Angular 2: Iterate over reactive form controls

Question

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

Answer 1

Using @Marcos answer I created a function that can be called passing a formGroup as parameter and it marks every formGroup children controls to dirty, just to make it usable from more places around the code putting it inside a service, for example.

public touchAllFormFields(formGroup: FormGroup): void {
    Object.keys(formGroup.controls).forEach((key) => {
        formGroup.get(key).markAsDirty();
    });
}

hope it helps ;)
