在 Kendo UI 网格中选择行时触发事件 (Angular 2)

Question

In Kendo UI (beta) for Angular 2、如何在选择特定行时触发事件？行本身没有指令或组件；因此，如果没有行元素，a (click)="triggeredFunction()" 将无法工作。

这是我的网格：

<kendo-grid [data]="gridData" [selectable]="true">

  <kendo-grid-column field="ProductName">
    <template kendoHeaderTemplate let-column let-columnIndex="columnIndex">
     {{column.field}}({{columnIndex}})
    </template>
  </kendo-grid-column>     

  <kendo-grid-column field="ProductName">
    <template kendoCellTemplate let-dataItem>
      <kendo-dropdownlist [data]="listItems"></kendo-dropdownlist>
    </template>
  </kendo-grid-column>

</kendo-grid>

这是我的组件：

@Component({
 selector: "ultron",
 styleUrls: [String("./ultron.component.less")],
 templateUrl: "./ultron.component.html",
 })
 export class UltronComponent {

   private gridData: any[] = [{
      "ProductID": 1,
      "ProductName": "Chai",
      "UnitPrice": 18.0000,
      "Discontinued": true,
    }, {
      "ProductID": 2,
      "ProductName": "Chang",
      "UnitPrice": 19.0000,
      "Discontinued": false,
    }
  }];

  private listItems: Array<string> = ["@", "$", "#", "%"];

  public triggeredFunction(){ ... }

}

Answer 1

您需要设置的选项是selectable，有效值为true和false，因为目前只支持单行选择。所以你的网格应该是这样的

<kendo-grid
      [data]="gridView"
      [selectable]="true"
    >
  </kendo-grid>

对于该事件，您需要附加一个 (selectionChange) 事件处理程序。这是一个plunkr

Answer 2

Kendo UI 中的选择通过可选择的选项启用。选定行索引和选定状态通过 selectionChange 事件提供。如果您还在网格中对数据进行排序或分页，那么您将绑定到 GridDataResult。要获取网格中选定行的绑定项，请使用 GridDataResult 的数据属性。请参阅以下代码示例：

import { Component } from '@angular/core';
import { GridDataResult, SelectionEvent } from "@progress/kendo-angular-grid";
import { SortDescriptor, orderBy } from "@progress/kendo-data-query";


@Component({
    selector: 'my-app',
    template: `
            <kendo-grid [data]="gridDataResult" [selectable]="true" [height]="500" 
                [sortable]="true" (selectionChange)="selectedRowChange($event)" 
                [sort]="sort" (sortChange)="sortChange($event)">
                <kendo-grid-column field="ProductID" title="Product ID" [width]="300"></kendo-grid-column>
                <kendo-grid-column field="ProductName" title="Product Name"></kendo-grid-column>
                <kendo-grid-column field="UnitPrice" title="UnitPrice"></kendo-grid-column>
                <kendo-grid-column field="Discontinued" title="Discontinued"></kendo-grid-column>
            </kendo-grid>
            `
})

export class AppComponent {
    public sort: SortDescriptor[] = [{ dir: "asc", field: "ProductID" }];

    private gridDataResult: GridDataResult;

    public products: any[] = [{
        "ProductID": 1,
        "ProductName": "Chai",
        "UnitPrice": 18.0000,
        "Discontinued": true,
    }, {
        "ProductID": 2,
        "ProductName": "Chang",
        "UnitPrice": 19.0000,
        "Discontinued": false,
    }
    ];

    protected sortChange(sort: SortDescriptor[]): void {
       this.sort = sort;
       this.gridDataResult = {
            data: orderBy(this.products, this.sort),
            total: this.products.length
        };
    }

    public selectedRowChange(selectionEvent: SelectionEvent) {
        let selectedItem = this.gridDataResult.data[selectionEvent.index];
        console.log(selectedItem);
    }
}

只是对原始答案的补充，除了 plunker 的一处更改外，它仍然是正确的

应该是this.gridView.data[e.index]
