Current behavior
Currently AbstractControl have two methods to enable/disable: enable() and disable().
So If I want to enable/disable according to another field I need to write:
this.petForm.get('hasDog')!.valueChanges.subscribe((newVal: boolean) => {
if (newVal) {
this.petForm.get('dogName')!.enable();
} else {
this.petForm.get('dogName')!.disable();
}
});Expected behavior
Add AbstractControl.setEnabled(enabled: boolean), so I can write:
this.petForm.get('petType')!.valueChanges.subscribe((newVal: string) => {
this.petForm.get('dogName')!.setEnabled(newVal === 'Dog');
this.petForm.get('catName')!.setEnabled(newVal === 'Cat');
});Minimal reproduction of the problem with instructions
What is the motivation / use case for changing the behavior?
