  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.

We can add a different property to ng-grid, such as paging, sorting, pinning of columns we need to display, enable scrolling and controlling a cell property value such as styling and events.
