Angular

Using Ng-grid in AngularUI Pages

It is a common requirement for any project to display data in a tabular format. The easiest way to do this is by using HTML tables, but soon this gets complex, you need a way to support sorting (single & multi columns), resizable columns, inline editing, filtering, pagination (client-side and server-side) and so on. There is a way to bind data to a HTML Table in AngularJs, but when it comes to sorting, paging, editing and dragging the columns, the grid choice is useful. ng-grid is Angular's native implementation of the Grid. There are many plugins from third-parties that can be integrated into AngularUI Pages, but ng-grid exists inside the AngularJs framework and is very rich in functionality and compatibility.

Let us create a sample ng-grid and understand how ng-grid works.

Example-1

  1. <!DOCTYPE html>  
  2. <html ng-app="myApp">  
  3. <head>  
  4.     <title>NG Grid Demo</title>  
  5.     <>  
  6.         .gridStyle  
  7.         {  
  8.             border: 5px solid #d4d4d4;  
  9.             width: 400px;  
  10.             height: 200px;  
  11.         }  
  12.     </style>  
  13.     <link rel="stylesheet" type="text/css" href="http://angular-ui.github.com/ng-grid/css/ng-grid.css" />  
  14.     <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script>  
  15.     <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.2/angular.min.js"></script>  
  16.     <script type="text/javascript" src="http://angular-ui.github.com/ng-grid/lib/ng-grid.debug.js"></script>  
  17.     <script type="text/javascript">  
  18.         var app = angular.module('myApp', ['ngGrid']);  
  19.         app.controller('MyCtrl', function ($scope) {  
  20.             $scope.Data = [{ Name: "Sachin", Skill: "ASP.NET" ,location:"Delhi"},  
  21.                              { Name: "Ramesh", Skill: "C#.NET, VB", location: "Chenai" },  
  22.                             { Name: "Pradeep", Skill: "ASP.NET MVC", location: "Bangalore" },  
  23.                              { Name: "Manas", Skill: "SQL Server", location: "Chenai" },  
  24.                            { Name: "Sachin", Skill: "ASP.NET", location: "Bangalore" }, ];  
  25.             $scope.gridOptions = { data: 'Data' };  
  26.         });  
  27.     </script>  
  28. </head>  
  29. <body ng-controller="MyCtrl">  
  30.     <div>  
  31.         <labl><b> Sample Demo to NG Grid</b></labl>  
  32.     </div>  
  33.     <div class="gridStyle" ng-grid="gridOptions"></div>  
  34. </body>  
  35. </html>  

Output

 

There are four steps to show a sample grid, if we observe the preceding code.

Passed "ngGrid" as dependency to the module

  1. var app = angular.module('myApp', ['ngGrid']);

Assign some data to scope

  1. [{Name: "Sachin", Skill: "ASP.NET" ,location:"Delhi"},];

Set the data of the scope to gridOptions as

  1. $scope.gridOptions = {data: ‘Data’};

It is like assigning a datasource to nggrid, similar to Gridview1.datasource=dataset in ASP.NET.

Bind the data to the page

  1. <div class="gridStyle" ng-grid="gridOptions"></div>

It is like binding data to a GridView, similar to Gridview1.dataBind() in ASP.NET.

Don't forget to add the scripts and styles needed for ng-grid in the head section of the code.

Let us create a DB and Bind data to ng-grid by web API calls.

Example-2

Step 1

Let us create an Employee Table.

 
Step 2

We will create a web API that will return the employee data.

  1. public class EmployeeAPIController : ApiController  
  2.     {  
  3.         private EmployeeEntities db = new EmployeeEntities();  
  4.          
  5.         public IEnumerable<Employee> GetEmployees()  
  6.         {  
  7.             return db.Employees.AsEnumerable();  
  8.         }  
  9.     }  

Step 3

Add module service controller and html code.

Module

  1. var app;  
  2. (function () {  
  3.     app = angular.module("EmployeeModule", ['ngGrid']);  
  4. })();  

Service

  1. app.service('EmployeeService', function ($http) {  
  2.   
  3.     this.getAllEmployee = function () {  
  4.         return $http.get("/api/EmployeeAPI");  
  5.     }  
  6. });  

Controller

  1. app.controller('EmployeeController', function ($scope, EmployeeService) {  
  2.     
  3.     GetAllRecords();  
  4.     function GetAllRecords() {  
  5.         var promiseGet = EmployeeService.getAllEmployee();  
  6.         promiseGet.then(function (pl) { $scope.Employees = pl.data, $scope.Data=pl.data },  
  7.               function (errorPl) {  
  8.                   $log.error('Some Error in Getting Records.', errorPl);  
  9.               });  
  10.     }  
  11.     $scope.gridOptions = { data: 'Data' };  
  12. });  

Index.html

  1. <html data-ng-app="EmployeeModule">  
  2. <head>  
  3.     <style type="text/css">  
  4.         .gridStyle  
  5.         {  
  6.             border: 5px solid #d4d4d4;  
  7.             width: 1000px;  
  8.             height: 200px;  
  9.         }  
  10.     </style>  
  11. </head>  
  12. <body data-ng-controller="EmployeeController">  
  13.   
  14.     <div class="gridStyle" ng-grid="gridOptions"></div>  
  15. </body>  
  16. </html>  
  17. <script src="~/Scripts/angular.js"></script>  
  18. <script src="~/Scripts/EmployeeScripts/Module.js"></script>  
  19. <script src="~/Scripts/EmployeeScripts/Service.js"></script>  
  20. <script src="~/Scripts/EmployeeScripts/Controller.js"></script>  
  21. <link rel="stylesheet" type="text/css" href="http://angular-ui.github.com/ng-grid/css/ng-grid.css" />  
  22. <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script>  
  23. <script type="text/javascript" src="http://angular-ui.github.com/ng-grid/lib/ng-grid.debug.js"></script>  

Output


Now, we have seen data from the database and binding to an ng-grid. Let us see now what the features are in ng-grid to make it more useful. We will do a sample ng-grid binding, editing, paging, sorting and grouping the records.

Code Explanation

Added data to scope

  1. $scope.myData = [{ "Company": "Samsung", "Model": "Samsung Galaxy Grand 2", "Price": 5000, "Stocks": 4 },  
  2.                                          { "Company": "Samsung", "Model": "Samsung Galaxy S3 Neo", "Price": 9000, "Stocks": 41 },  
  3.                                        { "Company": "Samsung", "Model": "Samsung Galaxy Grand Max", "Price": 11000, "Stocks": 4 },  
  4.                                         { "Company": "MicroMax", "Model": "Micromax Canvas Blaze", "Price": 6300, "Stocks": 0 },

  15.                             enableCellEdit: true  
  16.                         },  
  17.                         {  
  18.                             field: "Model",  
  19.                             width: 200,  
  20.                             enableCellEdit: true  
  21.                         },  
  22.                         {  
  23.                             field: "Price",  
  24.                             width: 100,  
  25.                             enableCellEdit: true  
  26.                         },  
  27.                         {  
  28.                             field: "Stocks",  
  29.                             width: 120,  
  30.                             enableCellEdit: true,  
  31.                             cellTemplate: basicCellTemplate  
  32.                         },  
  33.                         {  
  34.                             field: "Action",  
  35.                             width: 200,  
  36.                             enableCellEdit: false,  
  37.                             cellTemplate: '<button id="editBtn" type="button" class="btn btn-xs btn-info"  ng-click="updateCell()" >Click a Cell for Edit </button>'  
  38.                         }]  
  39.   
  40.             };  

Added the cell edit code on scope

  1. var basicCellTemplate = '<div class="ngCellText" ng-class="col.colIndex()" ng-click="editCell(row.entity, row.getProperty(col.field), col.field)"><span class="ui-disableSelection hover">{{row.getProperty(col.field)}}</span></div>';  

 Added the grouping code on scope and calling it on click of “CompanyByName and Price” button.

  1. $scope.changeGroupBy = function (group1, group2) {  
  2.   
  3. $scope.gridOptions.$gridScope.configGroups = [];  
  4.   
  5. $scope.gridOptions.$gridScope.configGroups.push(group1);  
  6.   
  7. $scope.gridOptions.$gridScope.configGroups.push(group2);  
  8.   
  9. $scope.gridOptions.groupBy();  
  10.   
  11. }  

This is all about the basics of ng-grid. I hope you have understood what ng-grid is and how to use it. Thanks for reading.
