如何获取Angular2中ag网格中选定行的数据？

我在 angular2 中设置了 ag-grid ，它工作正常，但我无法获取所选行的值...我的控制台窗口中没有错误...这就是我初始化网格的方式...

import {Component} from 'angular2/core';


@Component({
selector: 'aggride',
template: `

<div class="tr-card" >
<ag-grid-ng2  #agGrid of mgrid   class="ag-fresh"   rowHeight="40px"    
               [columnDefs]="columnDefs" 
                [rowData] = "rowData"
     enableCellExpressions="true"  
 enableSorting="true"  
  unSortIcon="true"
rowSelection="single"
(getSelectedRows) = "getSelectedRows()"
(onSelectionChanged) = "onSelectionChanged()"
>
</ag-grid-ng2>
</div>
`,
directives: [(<any>window).ag.grid.AgGridNg2],
})

这是我在类中获取所选值的代码

export class AgGride {
gridOptions = {
    columnDefs: 'columnDefs',
    rowData: 'rowData',
    rowSelection: 'single',
    getSelectedRows: 'getSelectedRows',
    onSelectionChanged: 'onSelectionChanged'
};

columnDefs = [
    { headerName: "Make", field: "make", editable: true },
    { headerName: "Model", field: "model", editable: true },
    { headerName: "Color", field: "Color", editable: true }
];

rowData = [
    { make: "Toyota", model: "Celica", Color: "Red"},
    { make: "Ford", model: "Mondeo", Color: "Blue"},
    { make: "Tata", model: "X100", Color: "Blue"},
    { make: "Volvo", model: "X5", Color: "White"},      
];

mgrid: any;
onSelectionChanged() {
    var selectedRows = this.mgrid.ag.this.gridOptions.getSelectedRows();
    console.log(selectedRows);


}
}

有人请告诉我如何纠正我的错误，以便我可以在控制台窗口中获取所选行的数据/值...

在模板上，例如：

(rowClicked)='onRowClicked($event)'
(cellClicked)='onCellClicked($event)'
(selectionChanged) = 'onSelectionChanged($event)'

然后是组件类：

onRowClicked(event: any) { console.log('row', event); }
onCellClicked(event: any) { console.log('cell', event); }
onSelectionChanged(event: any) { console.log("selection", event); }

使用 Chrome 控制台检查事件对象内容。
