Angular FormGroup validators (Not formControl validator)

Question

As known, we can add validators to specific formControl inside formGroup and we will get the validators error (true or false) by using controlname.errors.

I found that i can add validators to the FormGroup itself which is not bind directly to formControl and i thought i can find the errors of that validators by using formGroupName.errors but this property is always null.

Can someone help with that?

You can use myForm.controls('mygroup').hasError('name_of_error`') if is a groupName, or myFom.hasError('name_of_error') if is the form itself — Eliseo
@Eliseo i have only one formGroup... the errors array is null. — Omtechguy

You can add validator to the form group like this:

this.form = this.formbuilder.group({
<controls declared here>
    }, {validator: <your validator>});

You can then access the errors like this:

form.errors.<your_error_name>
