当服务调用选择新数据时，kendo angular 2 grid 自定义数据绑定问题不会绑定

Question

https://www.telerik.com/kendo-angular-ui/components/grid/columns/#toc-auto-generated-columns

Here Dynamically columns binding is missing:

The First time data binding correctly. The second time onwards it's not binding why?

this.gridData ---> is the Api response data

 this.gridView = {enter code here
          data: this.gridData,
          total: this.petService.pets.length
        };

Answer 1

“第二个开始”是什么意思？ Grid 究竟应该如何更新？

如果每次有新数据到达时，Grid 绑定的对象都会更新，则 Grid 将使用最新数据相应地重新渲染，例如：

ngOnInit() {
      this.interval = setInterval(() => {
        const rnd = Math.floor(Math.random()*sampleCustomers.length);
        this.gridData = sampleCustomers.slice(rnd, rnd + 10)
      }, 1000);
    }
