I am trying to use Angular Material Autocomplete component in my Angular 2 project. I added the following to my template.
<md-input-container>
<input mdInput placeholder="Category" [mdAutocomplete]="auto" [formControl]="stateCtrl">
</md-input-container>
<md-autocomplete #auto="mdAutocomplete">
<md-option *ngFor="let state of filteredStates | async" [value]="state">
{{ state }}
</md-option>
</md-autocomplete>
Following is my component.
import {Component, OnInit} from "@angular/core";
import {ActivatedRoute, Router} from "@angular/router";
import {FormControl} from "@angular/forms";
@Component({
templateUrl: './edit_item.component.html',
styleUrls: ['./edit_item.component.scss']
})
export class EditItemComponent implements OnInit {
stateCtrl: FormControl;
states = [....some data....];
constructor(private route: ActivatedRoute, private router: Router) {
this.stateCtrl = new FormControl();
this.filteredStates = this.stateCtrl.valueChanges.startWith(null).map(name => this.filterStates(name));
}
ngOnInit(): void {
}
filterStates(val: string) {
return val ? this.states.filter((s) => new RegExp(val, 'gi').test(s)) : this.states;
}
}
I'm getting the following error. It looks like the formControl
directive is not being found.
Can't bind to 'formControl' since it isn't a known property of 'input'
What is the issue here?
While using formControl
, you have to import ReactiveFormsModule
to your imports
array.
Example:
import {FormsModule, ReactiveFormsModule} from '@angular/forms';
@NgModule({
imports: [
BrowserModule,
FormsModule,
ReactiveFormsModule,
MaterialModule,
],
...
})
export class AppModule {}
