Angular2 No provider for ControlContainer when building a simple form

Question

This is my form:

app.component.html

    <         


        

Answer 1

You can use ngFormControl directive instead of ngControl and just pass control variable into child Input like this:

Child.component

@Component({
  selector: 'my-child-component',
  template: `
      
  `,
  directives: [FORM_DIRECTIVES]
})
export class Child {
  @Input() control: Control;
}

NgControl directive is required form tag within Child template
