How to set row selection to newly added row?

问题

I need to set selection to a newly added row. When $scope.gridApi.selection.selectRow(newObject) is entered, the grid's row model does not have the new row and thus can not select it. After method addRow is finished, the grid shows the new row (and the data) but no selection was made.

My test code:

$scope.addRow = function() {
    $scope.gridOptions.data.unshift({
        // my new data object
    });

    var newObject = $scope.gridOptions.data[0];
    $scope.gridApi.selection.selectRow(newObject);
};

How can I achieve this behavior?

Is there an event like 'rowAdded' in angularjs ui-grid I have to listen to? Is there anywhere a comprehensive list of events fired by ui-grid?

Thanks for help!

You can event listeners on row, column and so on. The documentation is here http://ui-grid.info/docs/#/api/ui.grid.class:Grid

You can add the data listener in onRegisterApi like below,

onRegisterApi : function(gridApi)
            {
                if(!$scope.gridApi) 
                {
                    $scope.gridApi = gridApi; 
                    $scope.gridApi.grid.registerDataChangeCallback(function(data)
                    {
                      $scope.gridApi.selection.selectRow($scope.gridOptions.data[0]);
                    }, [uiGridConstants.dataChange.ROW]);
                }
            }

and select any row you want to select.
