Introduction

The Kendo UI library provides a file uploader widget that can be used to upload multiple files to the server. On modern browsers such as Chrome, Safari, Firefox, and Opera, the files can be uploaded asynchronously using the HTML5 File API. The enhancements to the XmlHttpRequest object in HTML5, such as progress tracking, are also available. On legacy browsers, it falls back and uploads the file synchronously. In this chapter, we will see the various ways in which the file uploader widget can be used to upload files to the server, showing the progress of the file upload process and the options available to customize the widget.
