AngularJS UI网格过滤器取消事件

Question

Hi I am using angular ui grid, I have filter and grouping in the grid I am expanding by default all rows using following

$scope.expandAll = function(){
    $scope.gridApi.treeBase.expandAllRows();
  };

 $timeout(function() {
    $scope.expandAll();
}, 500);

now if user filter on any column which is not available in data

And then remove or cancel, It does not expand automatically

It shows like above

I need all rows to expand automatically when user clear or cancel filter data

I found there is an event filterChanged , but I don't know how to use that

I am using following plunkr for testing

Modify your onRegisterApi method to the following

onRegisterApi: function( gridApi ) {
  $scope.gridApi = gridApi;
  $scope.gridApi.core.on.filterChanged($scope, function() {        
    var grid = this.grid;
    var isfilterclear = true;
    angular.forEach(grid.columns, function( col ) {
      if(col.filters[0].term){
        isfilterclear = false;
      }
    });
    if(isfilterclear) {
        $timeout(function() {
            $scope.expandAll();
        },500);
    }
  });
}
