Can't bind to 'ngModel' since it isn't a known property of 'mat-slide-toggle'

Question

I am trying to get the current value of a mat-slide-toggle but unfortunatly I will get an error:

Error: Template parse errors: Can't bind to 'ngModel' since it isn't a known property of 'mat-slide-toggle'. 

I am using the toggle like this in the html part of my component:

 <mat-slide-toggle color="primary" [(ngModel)]="showInnerView">       Default Slide Toggle  </mat-slide-toggle> 

Corresponding property in my component:

showInnerView: boolean = false; 

What I am doing wrong?

Answer 1

ngModel lives in FormsModule of @angular/forms, so import that to your AppModule (or whichever module you are trying to use it in).

Also see this question: Angular 2 two way binding using ngModel is not working

Answer 2

Please try to include FormsModule in your corresponding Module like below

@NgModule({ imports: [ BrowserModule, FormsModule ], declarations: [ AppComponent ], bootstrap: [ AppComponent ] })
