Introduction
This article demonstrates MVC using angular file upload using bootstrap file style in Visual Studio 2017.
Angular File Upload
Angular file upload supports native Html5 uploads. It works with any server side platform which supports standard html form uploads. When file is added to the queue, it creates file item and uploader options are into this object. After, the items in the queue are ready for uploading.
Features
- Drag-n-drop upload
- Upload progress
- Validation file filter
- File upload queue
Follow the steps you can use angular file upload in angular JS in MVC
- Create MVC Project
- Configure Angular file upload & Bootstrap filestyle
- Work in Angular file upload
Create MVC Project
Open the visual studio 2017
![MVC]()
Go to New menu >Click New & project. Now it will open New Project Window
![MVC]()
You can select ASP.NET Web Application on Framework 4.5. Enter the name of project in “Solution name” textbox then click ok button.
![MVC]()
One more window should be appearing. Select MVC Template in this popup & Click ok button. Now start cropping image.
Configure Angular File Upload & Bootstrap Filestyle
Right click above the project and go to the NuGet package manager then search ‘angularfileupload’ in browse tab & install it.
![MVC]()
OR You can download the plug in from
Open the _Layout.cshtml and must refer the .js file from downloaded folder to this view page
- <script src="~/Plugin/angular/angular.min.js"></script>
- <script src="~/Plugin/angular-ui-router/release/angular-ui-router.min.js"></script>
- <script src="~/Plugin/angular-file-upload/dist/angular-file-upload.min.js"></script>
- <script src="~/Plugin/bootstrap-filestyle/src/bootstrap-filestyle.js"></script>
Link your angular configurable file, whatever you give as the name
- <script src="~/App/App.module.js"></script>
- <script src="~/App/App.config.js"></script>
- <script src="~/App/IUController.js"></script>
Angular Module
You will need to include the module as a dependency on your application.
- var uiroute = angular
- .module('uiroute', ['ui.router','angularFileUpload']);

Using bootstrap file style directive make it as a single uploading attribute. Based on attribute you can set
- <input filestyle="" type="file" data-icon-name="icon-upload" data-button-text="Single" data-class-button="btn btn-default" data-classinput="form-control inline" nv-file-select="" uploader="uploader" class="form-control" />
Html Code
Angular Controller
Initiate the Fileuploader to object. This object will load the predefined function.
- function FileUploadController(FileUploader) {
- var uploader = $scope.uploader = new FileUploader({
- url: 'server call'
- });
- uploader.filters.push({
- name: 'customFilter',
- fn: function (item, options) {
- return this.queue.length < 10;
- }
- });
- uploader.onWhenAddingFileFailed = function (item, filter, options) {
- console.info('onWhenAddingFileFailed', item, filter, options);
- };
- uploader.onAfterAddingFile = function (fileItem) {
- console.info('onAfterAddingFile', fileItem);
- };
- uploader.onAfterAddingAll = function (addedFileItems) {
- console.info('onAfterAddingAll', addedFileItems);
- };
- uploader.onBeforeUploadItem = function (item) {
- console.info('onBeforeUploadItem', item);
- };
- uploader.onProgressItem = function (fileItem, progress) {
- console.info('onProgressItem', fileItem, progress);
- };
- uploader.onProgressAll = function (progress) {
- console.info('onProgressAll', progress);
- };
- uploader.onSuccessItem = function (fileItem, response, status, headers) {
- console.info('onSuccessItem', fileItem, response, status, headers);
- };
- uploader.onErrorItem = function (fileItem, response, status, headers) {
- console.info('onErrorItem', fileItem, response, status, headers);
- };
- uploader.onCancelItem = function (fileItem, response, status, headers) {
- console.info('onCancelItem', fileItem, response, status, headers);
- };
- uploader.onCompleteItem = function (fileItem, response, status, headers) {
- console.info('onCompleteItem', fileItem, response, status, headers);
- };
- uploader.onCompleteAll = function () {
- console.info('onCompleteAll');
- };
-
- console.info('uploader', uploader);
Angular Directive
You can use bootstrap filestyle as angular directive. When you select the image using filestyle, set the element to the <img-crop> directive
- .directive('filestyle', filestyle);
-
- function filestyle() {
-
- controller.$inject = ['$scope', '$element'];
- return {
- restrict: 'A',
- controller: controller
- };
-
- function controller($scope, $element) {
- var options = $element.data();
- options.classInput = $element.data('classinput') || options.classInput;
-
- $element.filestyle(options);
- }
- }
Click F5 button and Run the Application. Now it will appear in the browser and you can see the result.
Output 1
![MVC]()
When you selected or dropped into the component, one or more filters are applied. Files which pass all filters are added to the queue.
Output 2
![MVC]()
This creates instance uploaders which are copied into the object.
Output 3
![MVC]()
Image queue is ready to upload the selected image.
