In Angular 2 you can simply add it to the config object:
import {Component} from '@angular/core';
import {DayPilot} from "daypilot-pro-angular";
@Component({
selector: 'angular2-scheduler-example',
template: `<daypilot-scheduler [config]="config"></daypilot-scheduler`
})
export class AppComponent {
config: any = {
// ...
timeRangeRightClickHandling: "Disabled"
}
}
