setvalue angular reactive form code example

Example 1: update formgroup value angular

To set all FormGroup values use, setValue:

this.myFormGroup.setValue({
  formControlName1: myValue1, 
  formControlName2: myValue2
});
To set only some values, use patchValue:

this.myFormGroup.patchValue({
  formControlName1: myValue1, 
  // formControlName2: myValue2 (can be omitted)
});

Example 2: reactive form programmatically set value

this.formRef.patchValue({
    field: value1,
    field2: value2,
    /* ... */
  });
