Learn MVC Using Angular UI-Route

Angular UI is a routing framework for a client-side, single page application and navigates from one view to another view. Angular UI-Router, however, is not just the “Route URL”; it maintains the application views based on a hierarchical tree of state. UI-Router provides a different approach than ngRoute, which we will be going over in this article. Also, the Angular UI-Router GitHub page can be found here.

Why Do We Use Angular UI-Router?

ngRoute is an Angular Core module, which is good for a basic route concept, but UI-Router contributes two different types of concepts, which are given below.

• State of the Application.
• Nested views of the complex page.

Example of a Nested View

How to Use UI-Router in ASP.NET MVC

Step 1

Open Visual Studio 2017 and go to File > New > Project.

Select the Web template and ASP.NET Web Application, as shown below:

Step 2

Choose MVC in ASP.NET 4.6 templates.

After the popup window, it will directly open the project solution, as shown below.

Step 3

Download AngularJS and the Angular UI-Router file.

• AngularJS Link.
• Angular UI-Router Link.
  

Create the new folder app, and add HTML and Javascript files, as shown above.

Let’s show the file name and the code.

home.html

<div class="jumbotron text-center">
    <h1>AngularJS UI Route</h1>
    <a ui-sref=".template" class="btn btn-primary">Nested State</a>
    <a ui-sref=".list" class="btn btn-primary"> Nested State with Ctrl </a>
    <a class="btn btn-primary" ui-sref="multipleview">Multiple View</a>  
</div>
<div ui-view></div>

homelist.html

div>Language List</div>
<div>
    <ul>
        <li ng-repeat="Lang in Language">{{ Lang }}</li>
    </ul>
</div>

datalist.html

<table class="table table-hover table-striped table-bordered">
    <thead>
        <tr>
            <td>Car List</td>
            
        </tr>
    </thead>
    <tbody>
    
        <tr ng-repeat="Car in CarList">
            <td>{{ Car}}</td>
        </tr>
        
    </tbody>
</table>

multipleview.html

<button class="btn btn-primary"  ui-sref="home">Home</button>
<div class="row">
    <div class="col-sm-12">
        <div ui-view="ViewOne"></div>
    </div>
</div>
<div class="row">
    <div class="col-sm-6">
        <div ui-view="ViewTwo"></div>
    </div>
    <div class="col-sm-6">
        <div ui-view="ViewThree"></div>
    </div>
</div>

App.module.js

var uiroute = angular
       .module('uiroute', ['ui.router']);

App.config.js

uiroute.config(function ($stateProvider, $urlRouterProvider) {
    $urlRouterProvider.otherwise('/home');
    $stateProvider
        // State managing 
        .state('home', {
            url: '/home',
            templateUrl: '/App/Test/home.html'
        })
         // nested list with data
        .state('home.template', {
            url: '/template',
            template: 'Welcome to the C# Corner'
        })
        // nested list with controller
        .state('home.list', {
            url: '/list',
            templateUrl: '/App/Test/homelist.html',
            controller: function ($scope) {
                $scope.Language = ['C#', 'VB', 'JavaScript','PHP'];
            }
        })

        // State with multiple views
        .state('multipleview', {
            url: '/multipleview',
            views: {
                '': { templateUrl: '/App/Test/multipleview.html' },
                'ViewOne@multipleview': { template: 'Welcome to the C# Corner!' },
                'ViewTwo@multipleview': {
                    templateUrl: '/App/Test/dataList.html',
                    controller: 'CarController'
                },
                'ViewThree@multipleview': {
                    templateUrl: '/App/Test/homelist.html',
                    controller: function ($scope) {
                        $scope.Language = ['C#', 'VB', 'JavaScript', 'PHP'];
                    }
                }
            }
        });

});

CarController.js

uiroute.controller('CarController', function ($scope) {

    $scope.CarList = ['Audi', 'BMW', 'Bugatti', 'Jaguar'];

});

Route Module:

“ui-router” – dependence module.
“$stateProvider, $urlRouterProvider” –state & Route provider
“$state”- Getting Parameter as a service
“$urlRouterProvider.otherwise”-default route provider
“ui-view” – template view directive.
“ui-sref” -link directive.
“uiroute” –this is the module name and mention the ng-app directive.

Step 4

Link the corresponding files in _Layout.html and mention the ui-view here, as shown below:

index.cshtml

<div ui-view></div>

_Layout.cshtml

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>@ViewBag.Title - My ASP.NET Application</title>
    @Styles.Render("~/Content/css")
    @Scripts.Render("~/bundles/modernizr")
    
</head>
<body>
    <div class="navbar navbar-inverse navbar-fixed-top">
        <div class="container">
            <div class="navbar-header">
                <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                </button>
            </div>
        </div>
    </div>
    <div class="container body-content" ng-app="uiroute">
        @RenderBody()
        <hr />
        <footer>
            <p>&copy; @DateTime.Now.Year - My ASP.NET Application</p>
        </footer>
    </div>

    @Scripts.Render("~/bundles/jquery")
    @Scripts.Render("~/bundles/bootstrap")
    <script src="~/Plugin/angular/angular.min.js"></script>
    <script src="~/Plugin/angular-ui-router/release/angular-ui-router.min.js"></script>
    <script src="~/App/App.module.js"></script>
    <script src="~/App/App.config.js"></script>
    <script src="~/App/CarController.js"></script>
    @RenderSection("scripts", required: false)
</body>
</html>

Once the above step completes, run the Application or click F5. The output is opened as a default browser.

Output 1 – Following $State

Output 2

Output 3 – Nested View Using Controller

Output 4 – Multiple Views of the Single Page
