@ViewChild(VirtualScroll) listView: VirtualScroll;

private scrollTo(index: number) {
let key = ‘#customIds_’ + index;

let hElement: HTMLElement = this.content._elementRef.nativeElement;
let element = hElement.querySelector(key);
element.scrollIntoView();

//wait till scroll animation completes
setTimeout(() => {
    //resize it! otherwise will not update the bufferRatio
    this.listView.resize();
},500);
