Select grid row item from code

问题

Is there any way to select a grid row from code so you can trigger the selectionChange event emitter? I don't know how to get hold of the grid component and execute the event manually.

Selection grid sample plunkr

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

--

Edit: If I access the grid manually by adding a #gridReference tag into the kendo-grid tag, I can access the component using

@ViewChild('activityGrid') gridReference: GridComponent;

But when executing

var selectionEvent = { index: 0, selected: false } as SelectionEvent;  
this.gridReference.selectionChange.emit(selectionEvent);

It still doesn't work. It migth work when I have to access the SelectionService using unselect but that's a private class.

Updated plunkr

Unfortunately, currently it is not possible to select a row programmatically via the public API.

The selectionChange emitter is there to trigger the selectionChange event and I'm afraid it will not trigger the selection logic.

This could be achieved now by utilizing the new SelectionDirective. It allows specifying the key to be stored when selecting a row and also the selectedKeys collection to hold reference to the selected keys. This also allows to programatically modify the selection.
