patch Value in a nested form control using angular2

Question

I need to set a value in a nested control in a FormBuiler and the model is the following:

this.addAccForm = this.fb.group({
      accid: [\'\', Validators.re         


        

Answer 1

Here is the code for working for me.

I am using Angular Version "^6.0.0"

var formArray = this.addAccForm.get("cyc") as FormArray;
formArray.at(0)["controls"]["cycid"].patchValue("Value that you want to pass");
