ngGrid Multi Column Filtering

Posted by: admin November 30, 2017 Leave a comment


I am using the ngGrid module for AngularJS to show some paged data. I want to be able to search across multiple columns, however using an OR search.

Lets say I have a column with the following headings: Id, Name, Description. When I search I want to return all rows where either Id OR name OR description contain the search term.

    $scope.pagingOptions = {
        pageSizes: [20, 50, 100],
        pageSize: 20,
        totalServerItems: 0,
        currentPage: 1

    $scope.gridOptions =
            data: 'myData',
            columnDefs: [
                { field: 'id', displayName: 'Id' },
                { field: 'name', displayName: 'Name' },
                { field: 'description', displayName: 'Description' },
                { displayName: 'Actions', cellTemplate: '<input type="button" data-ng-click="doSomething(row.entity)" value="Do Something" />'}],
            enablePaging: true,
            showFooter: true,
            showFilter: true,
            pagingOptions: $scope.pagingOptions,
            filterOptions: {
                filterText: "",
                useExternalFilter: false

I have tried using the default search box, and also using an external input box bound to $scope.filterText to define a custom filter such as:

$scope.filterUpdated = function () {
    $scope.gridOptions.filterOptions.filterText = 'id:' + $scope.filterText + ';name:' + $scope.filterText + ';description:' + $scope.filterText;

However this seems to do an AND on all of the columns. Is it possible to achieve what I want using the ngGrid module?

Thanks in advance,



Yes it’s possible to do an OR filter, but after searching in the ng-grid source code I can’t see how it can be done using their filterOptions.filterText. That can do AND filtering only.

The solution would be then to use filterOptions.useExternalFilter:true

I also found no examples of it, but after playing around with that for a bit, I got the notion that the filter is actually done by re-creating the gridOptions.data object|array. That is the only downside to this filter.

Plunker code is here

So basically your code would look like this index.html:

<body ng-controller="MyCtrl">
  <strong>Filter Name:</strong> </string><input type="text" ng-model="filterName"/>
  <strong>Filter Age:</strong> </string><input type="text" ng-model="filterAge"/>
  <button ng-click="activateFilter()">Run Filter</button>
  <div class="gridStyle" ng-grid="gridOptions"></div>

And in your controller.js:

app.controller('MyCtrl', function($scope) {

$scope.filterOptions = {
  filterText: '',
  useExternalFilter: true

$scope.activateFilter = function() {
  var name = $scope.filterName || null;
  var age = ($scope.filterAge) ? $scope.filterAge.toString() : null;
  if (!name && !age) name='';

  $scope.myData = angular.copy($scope.originalDataSet, []);
  $scope.myData = $scope.myData.filter( function(item) {
    return (item.name.indexOf(name)>-1 || item.age.toString().indexOf(age) > -1);

 $scope.originalDataSet = [{name: "Moroni", age: 50},
               {name: "Tiancum", age: 43},
               {name: "Jacob", age: 27},
               {name: "Nephi", age: 29},
               {name: "Enos", age: 34}];

 $scope.myData = angular.copy($scope.originalDataSet, []);

 $scope.gridOptions = {
  data: 'myData',
  filterOptions:  $scope.filterOptions

That’s just basic filtering (use regex and/or convert to lowercase for better matching). Also note that if both name and age are empty I set name to be ” and then every element would return true inside the filter (resulting in the whole dataset return).

This option is much better suited to dynamic dataset (read – server fed), but it works just as well but replicating the original dataset and applying the filters on it.
