Question

它还支持绑定到异步源

但是没有提供一个如何做到这一点的例子。请告知如何做到这一点？

Answer 1

只需将组合框绑定到您的异步数据，它就会自动检测可观察的更新或承诺解决方案

<kendo-combobox [data]="tickers" [valuePrimitive]="false" [textField]="'name'" >
</kendo-combobox> 
/* Obtain tickers from async operation */

Answer 2

通过async pipe绑定到异步数据（Observables）。应通过以下具体示例改进文档：

import { Component } from '@angular/core';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/observable/interval';
import 'rxjs/add/operator/bufferCount';

@Component({
    selector: 'my-app',
    template: `
    <kendo-combobox [data]="tickers | async"></kendo-combobox>
    `
})
export class AppComponent {
    /* Start with an empty observable */
    public tickers: Observable<number[]>;

    constructor() {
        /* Produce 1 random value each 1000ms
           and emit it in batches of 10. */
        this.tickers = Observable.interval(100)
            .bufferCount(10);
    }
}
