AngularJs: Display image in ASP.NET MVC application using ng-src

In this article I am going to explain how to display image in asp.net MVC application using AngularJs ng-src directive.


Description:
I have a table Employee and contain dummy data. I want to show the records in Grid/tabular format with profile image of employee.

Implementation:

We use the ng-repeat directive to display data and ng-src for image. Follow the below given steps to implement this functionality in your application.

Model:
Model Class (Employee.cs):
    public partial class Employee
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public Nullable<int> Phone { get; set; }
        public Nullable<int> Salary { get; set; }
        public string Department { get; set; }
        public string ImagePath { get; set; }
        public string EmailId { get; set; }
    }

Add controller:
Add empty controller to application. Create a json action to get the data.

Complete Code of Controller:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using MVC_Project.Models;
namespace MVC_Project.Controllers
{
    public class AngularController : Controller
    {
        //
        // GET: /Angular/
        DemoEntities1 db = new DemoEntities1();
        public ActionResult Index()
        {
            return View();
        }
        public JsonResult GetEmployees()
        {
            var city = db.Employees.ToList();
             return Json(city, JsonRequestBehavior.AllowGet);          
        }       
    }
}

Add view:
Add view for index action and design the page.

Complete structure of View:
@{
    ViewBag.Title = "MVC-AngualarJs Tutorial";
}
<style>
    table tr td th {
        text-align: center;
        border:none;
    }
    .ng-binding {
        padding: 40px;
    }
     a {
        text-decoration: none;
        color: #2196F3;
    }
     tr:nth-child(odd) {
        background: #b8d1f3;
    }
 
     tr:nth-child(even) {
        background: #dae5f4;
    }
</style>
<h2>MVC-AngualarJs Tutorial :Display data with image in grid format </h2>
<fieldset style="width:60%">
    <legend>AngualarJs Tutorial :Display data with image in Grid format </legend>

    <div ng-app="mvcapp" ng-controller="AngularController">  
       <table>         
           <tr>
               <th><a href="" ng-click="columnToOrder='id';reverse=!reverse">S.No.</a></th>
            
               <th class="name">
                   <a href="" ng-click="columnToOrder='Name';reverse=!reverse">Name</a>
               </th>
            
               <th class="name">
                   <a href="" ng-click="columnToOrder='Phone';reverse=!reverse">Phone</a>
               </th>
             
               <th class="name">
                   <a href="" ng-click="columnToOrder='Salary';reverse=!reverse">Salary</a>
               </th>
            
               <th class="name">
                   <a href="">Image</a>
               </th>
             
               <th class="name">
                   <a href="" ng-click="columnToOrder='EmailId';reverse=!reverse">Email</a>
               </th>
           </tr>
           <tr ng-repeat="emp in employees| filter:{Name:empname} |orderBy:columnToOrder:reverse">
               <td>{{$index+1}}</td>
             
               <td>{{emp.Name }}</td>
             
               <td>{{emp.Phone }}</td>
           
               <td>{{emp.Salary }}</td>
             
<td><img ng-src="{{emp.ImagePath || 'images/image.jpg'}}" alt="" title="{{emp.Name}}" width="150" height="150" /></td>             
               <td>{{emp.EmailId ||'email not available' }}</td>
           </tr>
       </table>
        <div ng-show="(employees|filter:empname).length==0" style="color:red;font-weight:bold">No Result Found</div>
    </div>
</fieldset>


    <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular.js"></script>
<script>
    var angular = angular.module('mvcapp', []);
    angular.controller('AngularController', function ($scope, $http) {     
        Getallitem()
        function Getallitem()
        {
            $http.get('/Angular/GetEmployees').success(function (data) {
                $scope.employees = data;
            });
        }   
    });
</script>

Build the application and run. Hope it helps you.
