How to get the data of selected row in ag grid in angular2?

问题

I have setup ag-grid in angular2 which works fine but i am not able to get the value of selected row...There are no errors in my console window...This is how i am initialising the grid...

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],
})

And this my code inside the class to get the selected value

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);


}
}

Somebody please tell me how can i correct my mistake so that i will get the data/value of selected row in my console window...

On template, e.g.:

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

and then on component class:

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

Use Chrome console to check the event object contents.

you can use api.getSelectedRows() that Returns a array of selected rows data.

 public getSelectedRows(){
        let rowsSelection = this.gridOptions.api.getSelectedRows();
        console.info(rowsSelection);
      }

that's work for me.

On your HTML bind rowClicked event to your own function as follows.

 <ag-grid-angular #grid
      style="width: 100%; height: 500px;" class="ag-theme-balham"
      [rowData]="rowList" [columnDefs]="columnsList" [rowSelection]="selectionMode"
      (rowClicked)="onRowClick($event)"
    >
    </ag-grid-angular>

then on your TS or in your JS use the api as follows

onRowClick(event) {
    if (this.selectionMode === 'multiple') {
      this.selectedEntity = this.grid.api.getSelectedRows();
    } else {
      this.selectedEntity = this.grid.api.getSelectedRows()[0];
    }
}

When your grid has a feature like multiple selections all the selected data won't pass with the event parameter. It will always be the selected row only.

Reason I didn't encourage the selectionChanged event was, It will always call the rowClicked event before selectionChanged event.

onRowSelected: params => {
  const selectedRows = params.api.getSelectedRows();
  console.log(selectedRows);
}
