You want to initialize gridOptions as a property of the class, not just a variable. So it should be this.gridOptions:

constructor(private _heroService: HeroService) {

    console.log("in Grid constructor...");

    this.columnDefs = [
        { headerName: "ID", field: "id", sortingOrder: ["asc", "desc"], editable: false, width: 100 },
        { headerName: "Name", field: "name", sortingOrder: ["asc", "desc"], editable: false, hide: false }
    ];

    this._heroService.getHeroes().then(heroes => this.rowData = heroes);

    this.gridOptions = {
        enableSorting: true,
        rowData: this.rowData,
        columnDefs: this.columnDefs,
        onReady: () => {
            this.gridOptions.api.sizeColumnsToFit();
            alert(this.gridOptions.api);
        }
    }
}
