AngularJS Question

angular ui-grid 3.0 get selected rows

This answer states that this code:

$scope.gridOptions.onRegisterApi = function(gridApi){

$scope.gridApi = gridApi;
$scope.mySelectedRows=$scope.gridApi.selection.getSelectedRows();
}


Should work in order to get the selected rows, but to me it returns always [], to get track of selected rows I have to call
gridApi.selection.getSelectedRows()
each time a selection event is triggered, is this correct ?

What I want to achieve is to do my own footer that tracks the number of selected rows of the grid, is this the correct way of achieving this ?

Answer

There is already an example of showing the number of selected elements in the footer.

This plnkr shows the selected items footer. http://plnkr.co/edit/jc1YPCXBmfOKWyu8sLkx?p=preview

If you want to do further analysis on the selected row you can register a listener for the row selection and act on that.

 $scope.gridOptions.onRegisterApi = function(gridApi){
      //set gridApi on scope
      $scope.gridApi = gridApi;
      gridApi.selection.on.rowSelectionChanged($scope,function(row){
        var msg = 'row selected ' + row.isSelected;
        $log.log(msg);
      });

      gridApi.selection.on.rowSelectionChangedBatch($scope,function(rows){
        var msg = 'rows changed ' + rows.length;
        $log.log(msg);
      });
    };
