I have issue using formControlName on Mat-Autocomplete. i dont know why but my formControlName wont send the data, am i put it wrong? When i try to remove [formControl] from HTML, its always cant filter.


<form [formGroup]="form" #legalDataFrm="ngForm" autocomplete="off""column" fxFlex="1 1 auto" novalidate>
  <input type="text" placeholder="Pilih Bank" 
    formControlName="bankName" matInput 
    [formControl]="myControl" [matAutocomplete]="auto">
      <mat-option>Pilih Bank</mat-option>
      <mat-option *ngFor="let option of filteredOptions | async" [value]="option">

TS _bankService is where i get the Bank List, _validationService is where i get the validation for each form name.

export class FpLegalDataFormComponent implements OnInit, OnDestroy {
form: FormGroup;
myControl = new FormControl();
options: User[];
filteredOptions: Observable<User[]>;

private activatedRoute: ActivatedRoute,
private formBuilder: FormBuilder,
public _validationsService: ValidationsService,
public _bankService: BankService
) {
 this.form ={
  bankName      : [bankName, Validators.required]
displayFn(user?: User): string | undefined {
return user ? user.bankName : undefined;

private _filter(name: string): User[] {
const filterValue = name.toLowerCase();

 return this.options.filter(option => 
 option.bankName.toLowerCase().indexOf(filterValue) > -1);
 private initDropdown() {
 this._bankService.getBank().then((response) => {
   this.options =;
   this.filteredOptions = this.myControl.valueChanges
     startWith<string | User>(''),
     map(value => typeof value === 'string' ? value : value.bankName),
     map(name => name ? this._filter(name) : this.options.slice())

First of all it's good to initialize the form control so insted of:

this.form ={
  bankName      : [bankName, Validators.required]


this.form ={
  bankName: new FormControl(bankName, Validators.required)

and to fix the problem insted of

<input type="text" placeholder="Pilih Bank" 
    formControlName="bankName" matInput 
    [formControl]="myControl" [matAutocomplete]="auto">


<input type="text" placeholder="Pilih Bank" matInput 
    [formControl]="form.get('bankName')" [matAutocomplete]="auto">

it should fix your problem.
