Can't bind to 'formControl' since it isn't a known property of 'input' - Angular2 Material Autocomplete issue
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 {}
Forget trying to decipher the example .ts - as others have said it is often incomplete.
Instead just click on the 'pop-out' icon circled here and you'll get a fully working StackBlitz example.
You can quickly confirm the required modules:
Comment out any instances of ReactiveFormsModule, and sure enough you'll get the error:
Template parse errors:Can't bind to 'formControl' since it isn't a known property of 'input'.
Another reason this can happen:
The component you are using formControl in is not declared in a module that imports the ReactiveFormsModule.
So check the module that declares the component that throws this error.
