how to get angular2 formcontrol parent

Question

How to get parent form group in a nested form group for a control. At the time of validation of a control, i need a sibling control value. Both these controls are part of formgroup, which is part of formArray. I know we have root, which gives the root element. How can I get immediate parent of a given form control.

Answer 1

You can access the parent of a given FormControl with .parent the same way you would be using .root.
