Property Description
@Input()ngTemplateOutletContext: Object
@Input()ngTemplateOutlet: TemplateRef<any>

Description

You can attach a context object to the EmbeddedViewRef by setting [ngTemplateOutletContext]. [ngTemplateOutletContext] should be an object, the object's keys will be available for binding by the local template let declarations.

<ng-container *ngTemplateOutlet="templateRefExp; context: contextExp"></ng-container>

Using the key $implicit in the context object will set its value as default.

Example

@Component({
  selector: 'ng-template-outlet-example',
  template: `
    <ng-container *ngTemplateOutlet="greet"></ng-container>
    <hr>
    <ng-container *ngTemplateOutlet="eng; context: myContext"></ng-container>
    <hr>
    <ng-container *ngTemplateOutlet="svk; context: myContext"></ng-container>
    <hr>
    
    <ng-template #greet><span>Hello</span></ng-template>
    <ng-template #eng let-name><span>Hello {{name}}!</span></ng-template>
    <ng-template #svk let-person="localSk"><span>Ahoj {{person}}!</span></ng-template>
`
