Angularjs : Show message on empty ng-repeat

In this article I am going to explain how to show message No Result Found when filter is empty in ASP.NET MVC using AngularJs.

In the previous article I have explained how to perform Create, read, Update andDelete (CRUD) operations in Asp.net MVC 5 using AngularJs, how to display imagein asp.net MVC application using AngularJs ng-src directive and how to displaydata in tabular format using AngularJs in asp.net MVC application.

Description:

I am displaying the employees detail in Grid using ng-repeat. I want to show message when matched records not found on filter.

Implementation:

To show message add the below given snippets:

<div ng-show="(employees|filter:empname).length==0" style="color:red;font-weight:bold">No Result Found</div>

Example:

Here in this example I want to filter the records based on employee name.

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 emp = db.Employees.ToList();

            return Json(emp, JsonRequestBehavior.AllowGet);          

        }       

    }

}

View (index.cshtml):

@{

    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;

    }

    /*  Define the background color for all the EVEN background rows  */

     tr:nth-child(even) {

        background: #dae5f4;

    }

</style>

<h2>MVC-AngualarJs Search(Filter) Tutorial</h2>

<fieldset style="width:60%">

    <legend>AngualarJs Search(Filter) Tutorial</legend>

    <div ng-app="mvcapp" ng-controller="AngularController">    

              <table>

           <tr>

               <td>Search :</td>

               <td colspan="2"><input type="text" ng-model="empname" placeholder="Search"></td>

           </tr>

           <tr>

               <td></td>

               <td></td>

           </tr>

       </table>

  

       <table>         

           <tr>

               <th>

               <th>

                   <a href="" ng-click="columnToOrder='Department';reverse=!reverse">Department</a>

               </th>

          

               <th>

                   <a href="" ng-click="columnToOrder='Salary';reverse=!reverse">Salary</a>

               </th>

            

               <th>

                   <a href="">Image</a>

               </th>

             

               <th >

                   <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.Department}}</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) {

            $http.get('/Angular/GetEmployees').success(function (data) {            

                $scope.employees = data;

            });

         

    });

</script>

Now build and run the project. Search the record which not exist in database.
