I am looking to enhance my FormGroup by implementing an If condition

This is a FormGroup that I have created:

myFormGroup = new FormGroup({

languageType: new FormControl("", Validators.required),
facilityId: new FormControl(""),
timeZone: new FormControl("", Validators.required),
name: new FormControl("", Validators.required),
address: new FormControl("", Validators.required),
branch: new FormControl(""),

}

I am attempting to update the 'branch' field as required within an if condition. This is what I have tried:

  if(count > 0) {

    this.myFormGroup = new FormGroup({
      branch: new FormControl("", Validators.required)

  });

}

However, this approach is not functioning as expected.

Answer №1

To apply a validator, you can utilize the setValidators method.

this.repairFacilityForm.controls["branch"].setValidators(Validators.required);

Answer №2

Experiment with this approach 

languageTypeId: new FormControl("", [Validators.required]),

Include Validation in Array Section
