Angular 2: Iterate over reactive form controls

Issue

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

Solution

Found out that Object.keys can handle this..

    Object.keys(this.form.controls).forEach(key => {
      this.form.get(key).markAsDirty();
    });

For Angular 8+, use the following (based on Michelangelo answer):

    Object.keys(this.form.controls).forEach(key => {
      this.form.controls[key].markAsDirty();
    });
