Cannot find control with name: formControlName in angular reactive form

Question

I found this problem in many questions in stackoverflow but no luck. Please help me for figuring out what I am doing wrong.

In component :

ngOnInit() {
    this.companyCreatForm = this._formBuilder.group({
      name: [null, [Validators.required, Validators.minLength(5)]],
      about: [null, [Validators.required]],
      businessType: [null, [Validators.required]],
      address: this._formBuilder.group({
        street: [],
        website: [null, [Validators.required]],
        mobile: [null, [Validators.required]],
        email: [null, [Validators.required]],
        pageId: [null, [Validators.required]],
      }),
    });

Form :

<form [formGroup]="companyCreatForm" (ngSubmit)="creat_company()" novalidate class="form-horizontal">
    <div class="panel panel-default" *ngIf="generalPanel">
        <div class="panel-heading">General Info</div>
        <div class="panel-body">
            <div class="form-group">
                <label for="comapny name" class="col-sm-3 control-label">Company's Name</label>
                <div class="col-sm-8">
                    <input type="text" class="form-control" placeholder="Company's Name" formControlName="name" #refName>
                    <div *ngIf="companyCreatForm.controls['name'].hasError('required') && refName.touched" class="alert alert-danger">
                        please enter name
                    </div>
                    <div *ngIf="companyCreatForm.controls['name'].hasError('minlength')" class="alert alert-danger">

Answer 1

You should specify formGroupName for nested controls

<div class="panel panel-default" formGroupName="address"> <== add this
    <div class="panel-heading">Contact Info</div>

Plunker Example

Answer 2

In your HTML code

<form [formGroup]="userForm">
    <input type="text" class="form-control"  [value]="item.UserFirstName" formControlName="UserFirstName">
    <input type="text" class="form-control"  [value]="item.UserLastName" formControlName="UserLastName">
</form>

In your Typescript code

export class UserprofileComponent implements OnInit {
    userForm: FormGroup;
    constructor(){ 
       this.userForm = new FormGroup({
          UserFirstName: new FormControl(),
          UserLastName: new FormControl()
       });
    }
}

This works perfectly, it does not give any error.

Answer 3

you're missing group nested controls with formGroupName directive

    <div class="panel-body" formGroupName="address">
      <div class="form-group">
        <label for="address" class="col-sm-3 control-label">Business Address</label>
        <div class="col-sm-8">
          <input type="text" class="form-control" formControlName="street" placeholder="Business Address">
        </div>
      </div>
      <div class="form-group">
        <label for="website" class="col-sm-3 control-label">Website</label>
        <div class="col-sm-8">
          <input type="text" class="form-control" formControlName="website" placeholder="website">
        </div>
      </div>
      <div class="form-group">
        <label for="telephone" class="col-sm-3 control-label">Telephone</label>
        <div class="col-sm-8">
          <input type="text" class="form-control" formControlName="mobile" placeholder="telephone">
        </div>
      </div>
      <div class="form-group">
        <label for="email" class="col-sm-3 control-label">Email</label>
        <div class="col-sm-8">
          <input type="text" class="form-control" formControlName="email" placeholder="email">
        </div>
      </div>
      <div class="form-group">
        <label for="page id" class="col-sm-3 control-label">Facebook Page ID</label>
        <div class="col-sm-8">
          <input type="text" class="form-control" formControlName="pageId" placeholder="facebook page id">
        </div>
      </div>
      <div class="form-group">
        <label for="about" class="col-sm-3  control-label"></label>
        <div class="col-sm-3">
          <!--span class="btn btn-success form-control" (click)="openGeneralPanel()">Back</span-->
        </div>
        <label for="about" class="col-sm-2  control-label"></label>
        <div class="col-sm-3">
          <button class="btn btn-success form-control" [disabled]="companyCreatForm.invalid" (click)="openContactInfo()">Continue</button>
        </div>
      </div>
    </div>
