AngularJs: Show default image with asp.net mvc

In this article I am going to explain how to show default image if image is missing or not uploaded using angularjs with asp.net mvc.

In the previous article I have explained how to display message when ng-repeat filter is empty or null using AngularJs with MVC, how to show message No Result Found whenfilter is empty in ASP.NET MVC using AngularJs , how to perform Create, read,Update and Delete (CRUD) operations in Asp.net MVC 5 using AngularJs, how todisplay image in asp.net MVC application using AngularJs ng-src directive and howto display data in tabular format using AngularJs in asp.net MVC application.

Description:

I am displaying the employees detail like name, phone number, email, profile pic etc. in Grid using ng-repeat. If users do not upload profile pic or missing, in that case show default image.

Implementation:

To display default image add the below given snippets:

<img ng-src="{{emp.ImagePath || 'images/default.jpg'}}" alt="" title="{{emp.Name}}" width="150" height="150" />

Example:

Here in this example I want to display default image if image is missing.

    public class AngularController : Controller

    {

        //

        // GET: /Angular/

        DemoEntities1 db = new DemoEntities1();

        public ActionResult Index()

        {

            return View();

        }

        public JsonResult GetEmployees()

        {

            var emp = db.Employees.ToList();

            return Json(emp, JsonRequestBehavior.AllowGet);          

        }
