set form manually to invalid angular 2+

Question

Is there a way to set a formGroup to invalid state manually?

I tried myForm.invalid = true; and also myForm.status = 'INVALID'

But invalid and status are const.

I dont want to mark a specific control as invalid. But the whole form.

Try this:

myForm.setErrors({ 'invalid': true });

Worked for me. To make it valid I also did myForm.setErrors(null) – L1ghtk3ira May 31 '18 at 20:09

Fyi... You can also use setErrors the same way on a specific form element. – zeusstl Jul 03 '20 at 02:20

Try this formData.form.controls['email'].setErrors({'incorrect': true});
