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

Try with theese codes

this.addAccForm.patchValue({cyc: {cycid: 1234567 }});

this.addAccForm.patchValue({cyc: { det : {dcycid: 9876543}}});

Another solution is:

(< FormGroup >this.addAccForm.controls['cyc']).controls['cycid'].patchValue('1234567');
(< FormGroup >this.addAccForm.controls['cyc']).controls['det'].controls['dcycid'].patchValue('1234567');
