@ViewChild returns undefined

For some reason my @ViewChild in my Angular 5 App does not work. I have defined it like this in my component:

case-detail.component.html:

<div class="inner-tab-content" #innerTabContent>
    <!-- // more content here -->
</div>

I have implemented @ViewChild in my controller (above the constructor) like this:

case-detail.component.ts

@ViewChild('innerTabContent') tabContentElement: ElementRef;

And I want to access it here in the component: case-detail.component.ts

ngAfterViewInit() {
    console.log("scroll top: " + this.tabContentElement.nativeElement);
}

I've implemented the AfterViewInit interface. ngAfterViewInit() is called correctly. However, this.tabContentElement is always undefined.

Any help is greatly appreciated :)

ViewChild() works fine on latest plunker Angular version with the scenario you describe.

Demonstration in this plunker : https://plnkr.co /edit/KzWnkE5Hvp7NUow6YAxy

EDIT: Here is a replacement StackBlitz for the above Plunker: https://stackblitz.com/edit/angular-ivy-pzaglm

component :

ngAfterViewInit() {
    console.log(this.testView); // correctly outputs the element in console, not undefined
}

• Check that ElementRef and ViewChild are correctly imported from '@angular/core'

• Your element might simply not be there at the time of AfterViewInit (in case there is a *ngIf, for instance. (seems the case as per your comments)

In the latter case, you can use a wrapper element and ViewChildren , that emits some event when a new child element is added - more info on documentation here : https://angular.io/api/core/ViewChildren

note that there might be some issue with native div as per this question : @ViewChildren does not get updated with dynamically added DOM elements , but this can be worked around by using a new component that wraps your div, for instance.

EDIT

Or you can also use a timeout to wait for the component to be rendered. I must say that I find this solution 'dirty', but glad it works for you :)
