File Uploader


This demo shows how to use the allowedFileExtensions and maxFileSize options to limit the maximum size and specify file extensions that the FileUploader accepts. Note that demonstrated validation is client-side — you should implement the server-side validation. You can see an example under the FileUploaderController tab in the ASP.NET MVC version of this demo.

Copy to CodePen
var DemoApp = angular.module('DemoApp', ['dx']); DemoApp.controller('DemoController', function DemoController($scope) { $scope.fileUploaderImages = { multiple: true, uploadMode: "useButtons", uploadUrl: "", allowedFileExtensions: [".jpg", ".jpeg", ".gif", ".png"] }; $scope.fileUploaderMaxSize = { multiple: true, uploadMode: "useButtons", uploadUrl: "", maxFileSize: 4000000 }; });
