This tutorial explains how to create a datagrid similar to ASP.NET gridview with client side paging, searching and sorting functionality using AngularJS, PHP, MySQL. Following are links to the demo and download of the final application.

I have used angular-ui directive for the user interface of paging and some basic functionality.

While working with angularjs I found out the biggest issue using angular is it makes the Browser DOM slow while displaying huge amount of data. Hence it becomes necessary to load data partially through paging or infinite scrolling.

When we implement paging the data is divided into number of small pages. Hence the browser has to load less amount of data at one stretch. Which in turn increases the data loading speed.

Database setup:

Download the source code and import customers.sql to your MySQL database.

I’ve structured the entire application into 5 different folders

CustomersTable

This contains all the information about customers which we intend to display in our grid.

CREATE TABLE IF NOT EXISTS `customers` (
`customerNumber` int(11) NOT NULL,
`customerName` varchar(50) NOT NULL,
`contactLastName` varchar(50) NOT NULL,
`contactFirstName` varchar(50) NOT NULL,
`addressLine1` varchar(50) NOT NULL,
`addressLine2` varchar(50) DEFAULT NULL,
`city` varchar(50) NOT NULL,
`state` varchar(50) DEFAULT NULL,
`postalCode` varchar(15) DEFAULT NULL,
`country` varchar(50) NOT NULL,
`salesRepEmployeeNumber` int(11) DEFAULT NULL,
`creditLimit` double DEFAULT NULL,
PRIMARY KEY (`customerNumber`),
KEY `salesRepEmployeeNumber` (`salesRepEmployeeNumber`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

/includes/db.php

– Contains database configuration settings

<?php
$DB_HOST = '127.0.0.1';
$DB_USER = 'root';
$DB_PASS = '';
$DB_NAME = 'angularcode_grid';
$mysqli = new mysqli($DB_HOST, $DB_USER, $DB_PASS, $DB_NAME);
?>

/ajax/getCustomers.php

– Contains php files which needs server side communication

  • Connect to MySQL database
  • Retrieve all the customers and convert into JSON format
<?php
include('../includes/config.php');
$query="select distinct c.customerName, c.addressLine1, c.city, c.state, c.postalCode, c.country, c.creditLimit from customers c order by c.customerNumber";
$result = $mysqli->query($query) or die($mysqli->error.__LINE__);
$arr = array();
if($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
$arr[] = $row;
}
}
# JSON-encode the response
$json_response = json_encode($arr);
// # Return the response
echo $json_response;
?>

/app/app.js

– AngularJs application codes

  • Get all the customers returned by the ajax/getCustomers.php and store it in our applications scope
  • Implement paging, sorting and filter functionalities
var app = angular.module('myApp', ['ui.bootstrap']);
app.filter('startFrom', function() {
return function(input, start) {
if(input) {
start = +start; //parse to int
return input.slice(start);
}
return [];
}
});
app.controller('customersCrtl', function ($scope, $http, $timeout) {
$http.get('ajax/getCustomers.php').success(function(data){
$scope.list = data;
$scope.currentPage = 1; //current page
$scope.entryLimit = 5; //max no of items to display in a page
$scope.filteredItems = $scope.list.length; //Initially for no filter
$scope.totalItems = $scope.list.length;
});
$scope.setPage = function(pageNo) {
$scope.currentPage = pageNo;
};
$scope.filter = function() {
$timeout(function() {
$scope.filteredItems = $scope.filtered.length;
}, 10);
};
$scope.sort_by = function(predicate) {
$scope.predicate = predicate;
$scope.reverse = !$scope.reverse;
};
});

/css/bootstrap.css

– Adds bootstrap styles to our application

/js

– Contains supporting javascript library files [angular.min.js, ui-bootstrap-tpls-0.10.0.min.js]

index.html

The index.html file which contains the datagrid

<!DOCTYPE html>
