angularjs - angular ui grid save and restore state

Question

I need to know how to implement save and restore state in angularui grid without using any buttons. I need to save the state automatically when ever we do any changes in the grid. We have to auto restore the saved state also. Even if we refresh the page the saved state should be restored

Answer 1

Here's what I figured out. I couldn't find a single event for grid state changes, but It does look like they have individual events for almost everything. Here are a few that i'm using. I just set a break point in the onRegisterApi callback and dug through the gridApi object to find the events. http://plnkr.co/edit/LAMZvOkpx6jsD4CWSz04?p=preview

HTML:

<div ui-grid="gridOptions"
     ui-grid-selection 
     ui-grid-resize-columns 
     ui-grid-auto-resize 
     ui-grid-move-columns 
     ui-grid-grouping 
     ui-grid-save-state>
</div>

JS:

$scope.gridOptions = {
  data: [
    { name: 'Jack', title: 'manager', phone: '123456789', location: 'india'},
    { name: 'Suzy', title: 'developer', phone: '465189798', location: 'usa'},
    { name: 'George', title: 'secretary', phone: '82656517', location: 'japan'},
    { name: 'Michael', title: 'analyst', phone: '31321687', location: 'egypt'},
    { name: 'Sara', title: 'consultant', phone: '59595847', location: 'germany'},
    { name: 'Chris', title: 'engineer', phone: '789456123', location: 'russia'},
    { name: 'Elizabeth', title: 'clerk', phone: '963852741', location: 'china'},
    { name: 'Jane', title: 'intern', phone: '147258369', location: 'australia'},
    { name: 'Bill', title: 'accountant', phone: '951487623', location: 'brazil'}
  ],
  columnDefs: [
    { name: 'name' },
    { name: 'title' },
    { name: 'phone' },
    { name: 'location' }
  ],
  enableGridMenu: true,
  enableRowSelection: true,
  enableRowHeaderSelection: false,
  enableColumnResizing: true,
  enableColumnReordering: true,
  enableFiltering: true,
  onRegisterApi: function(gridApi) {
    // Keep a reference to the gridApi.
    $scope.gridApi = gridApi;

    // Setup events so we're notified when grid state changes.
    $scope.gridApi.colMovable.on.columnPositionChanged($scope, saveState);
    $scope.gridApi.colResizable.on.columnSizeChanged($scope, saveState);
    $scope.gridApi.grouping.on.aggregationChanged($scope, saveState);
    $scope.gridApi.grouping.on.groupingChanged($scope, saveState);
    $scope.gridApi.core.on.columnVisibilityChanged($scope, saveState);
    $scope.gridApi.core.on.filterChanged($scope, saveState);
    $scope.gridApi.core.on.sortChanged($scope, saveState);

    // Restore previously saved state.
    restoreState();
  }
};

function saveState() {
  var state = $scope.gridApi.saveState.save();
  localStorageService.set('gridState', state);
}

function restoreState() {
  $timeout(function() {
    var state = localStorageService.get('gridState');
    if (state) $scope.gridApi.saveState.restore($scope, state);
  });
}
