In my previous tutorial I had discuss and explain about crud (create, read, update and delete) using mvc web api, angularjs and bootstrap css.
Now I am going to explain that how can we achieve paging, sorting and filter in grid by using ng-table api of angularjs. In this article we will replace some code with previous tutorial so please download the code of previous article or you can follow the previous article in order to achieve.
Functionality we will achieve after doing this article:
1) Paging.
2) Sorting.
3) Filtering.
Let’s start step by step so that we can achieve our objective at the end of this article. After completing this demo our application should look like this:
1) Include this package in your existing application:
a) ngTable
It supports sorting, filtering and pagination. Header row with titles and filters automatic generated on compilation step.
2) Add the highlighted reference in your Index.cshtml file. This will add the reference of ngTable api of angularjs in our application. After adding this only we can use its sorting, paging and filter features.

<body>
<div class="main container" ng-view>
</div>
</body>
</html>
3) In list.html, replace the code with the following. I highlighted some of the changes part so it will be easy for us identity the code of functionalities given by this tutorial.
<div>
<a href="#/create" class="btn">Create</a>
</div>
<div class="row">
<div class="col-lg-offset-8 col-lg-4">
<input type="text" class="form-control" placeholder="Search for..." ng-model="search" />
</div>
</div>
<hr />
<div class="table-responsive">
<p class="text-right">
<strong>Page:</strong> {{tableParams.page()}}, <strong>Count per page:</strong>
{{tableParams.count()}}</p>
<table class="table table-striped table-bordered" ng-table="tableParams" template-pagination="custom/pager">
<tr ng-repeat="item in $data | filter:search">
<td data-title="'Employee Id'" sortable="'EmployeeId'">
{{ item.EmployeeId }}
</td>
<td data-title="'First Name'" sortable="'FirstName'">
{{ item.FirstName }}
</td>
<td data-title="'Last Name'" sortable="'LastName'">
{{ item.LastName }}
</td>
<td data-title="'Description'">
{{ item.Description }}
</td>
<td data-title="'Salary'" sortable="'Salary'">
{{ item.Salary | number: 2 }}
</td>
<td data-title="'Country'" sortable="'Country'">
{{ item.Country }}
</td>
<td data-title="'State'" sortable="'State'">
{{ item.State }}
</td>
<td data-title="'Date of Birth'" sortable="'DateofBirth'">
{{ item.DateofBirth | date }}
</td>
<td data-title="'Is Active'">
<span class="label" ng-class="{true:'label-success', false:'label-danger', '':'hidden'}[item.IsActive]">
{{ item.IsActive ? 'Active' : 'In Active' }}</span>
</td>
<td>
<a href="#/edit/{{item.EmployeeId}}" class="glyphicon glyphicon-edit"></a>
</td>
<td>
<a href="#/delete/{{item.EmployeeId}}" class="glyphicon glyphicon-trash"></a>
</td>
</tr>
</table>
<script type="text/ng-template" id="custom/pager">
<ul class="pager ng-cloak">
<li ng-repeat="page in pages"
ng-class="{'disabled': !page.active, 'previous': page.type == 'prev', 'next': page.type == 'next'}"
ng-show="page.type == 'prev' || page.type == 'next'" ng-switch="page.type">
<a ng-switch-when="prev" ng-click="params.page(page.number)" href="">« Previous</a>
<a ng-switch-when="next" ng-click="params.page(page.number)" href="">Next »</a>
</li>
<li>
<div class="btn-group">
<button type="button" ng-class="{'active':params.count() == 5}" ng-click="params.count(5)" class="btn btn-default">5</button>
<button type="button" ng-class="{'active':params.count() == 10}" ng-click="params.count(10)" class="btn btn-default">10</button>
<button type="button" ng-class="{'active':params.count() == 20}" ng-click="params.count(20)" class="btn btn-default">20</button>
<button type="button" ng-class="{'active':params.count() == 50}" ng-click="params.count(50)" class="btn btn-default">50</button>
</div>
</li>
</ul>
</script>
</div>
4) In controller.js, only replace declaration section of EmpControllers and ListController definition.
var EmpControllers = angular.module("EmpControllers", ['ngTable']);
// this controller call the api method and display the list of employees
// in list.html
EmpControllers.controller("ListController", ['$scope', '$http', '$filter', 'ngTableParams',
function ($scope, $http, $filter, ngTableParams) {
$scope.headers = [
{ column: "FirstName" },
{ column: "LastName" }
];
$http.get('/api/employee').success(function (data) {
$scope.tableParams = new ngTableParams({
page: 1, // show first page
count: 5, // count per page
sorting: {
EmployeeId: 'asc' // initial sorting
}
}, {
total: data.length,
getData: function($defer, params) {
var orderedData = params.sorting() ?
$filter('orderBy')(data, params.orderBy()) :
data;
$defer.resolve(orderedData.slice((params.page() - 1) * params.count(), params.page() * params.count()));
}
});
});
}]
);
