I have found a solution to set the value.


this.issuerConfigForm.controls['iinprefix'].patchValue("20");





Use setValue, not patchValue

setValue


patchValue





@Envil setValue is used for to set the value of all fields of form and patchValue is used for to set the value of specific field in form. Here vishnu just wanted to set the value of one field
