Set Form to Pristine without clearing data

Question

I have a form that displays a list of elements. They all share a common save button which is disabled until the form becomes dirty. Then

Answer 1

If you happen to be using Template-Driven forms and you have something like this in your component: @ViewChild('myForm') myform: NgForm;

I've found that the markAsPristine() is a function on the form property of your form. So it would be this.myform.form.markAsPristine().

Just thought I'd add this in case others come across markAsPristine() as not being defined.
