Multi-File Upload

Just like our Web File Manager, the File Upload control supports multi-file selection/upload. Once you've integrated the File Upload component in your ASP.NET project, your users can select multiple files within the File Open dialog and execute upload operations for all selected files simultaneously or drag files to external drop zones.

With integrated file extension and file size validation, you can automatically validate file information on the server and provide descriptive error messages.

Upload Large Files

To provide you as much control over file upload operations as possible, our ASP.NET File Upload control includes two Upload Modes.

In Standard Mode, uploaded files are sent to the server in a single request. In Advanced Mode, files are sent to the server in small packets (one at a time).

Drag & Drop Support

Your users can select multiple files and drag them to the File Upload control. The drag and drop functionality requires HTML5 support.


Supported browsers: IE10+, Safari 6+, Firefox 4+, Google Chrome, Opera 12+

Progress Panel

Our File Upload control includes a built-in Progress Panel to help communicate the state of individual upload operations. Should your needs dictate a custom solution, you can use the File Upload's API to create custom Progress Panels as needed.

Additional Info

Customizable ASP.NET Themes

The DevExpress ASP.NET Subscription ships with 20+ highly polished themes for your next web application. You can use each of these themes easily, without modification or manipulate them using our free ASP.NET Theme Builder application. See Demo

Sec 508 and Accessibility

The DevExpress ASP.NET Subscription makes it easy to create web applications that meet government regulations regarding web accessibility. Sec 508 and Web Content Accessibility Guidelines 1.0 support is available across our entire DevExpress ASP.NET Product Line. Read about accessibility

Touch and Mobile Device Enabled

Deliver elegant, touch-enabled ASP.NET and MVC web applications using the platform you know and love. The ASP.NET Subscription helps you leverage your current investments and address customer needs via a comprehensive range of Web Forms Controls and MVC Extensions that support touch on iOS Safari, Android and Internet Explorer 10.

AJAX Enabled with Rich Client-Side API

Each and every control provides an ability to update the control using callbacks, eliminating the need to re-load the entire page. This callback functionality allows you to optimize how data is transferred to the client. We also offer you a comprehensive client-side API, along with the ability to handle events on the client side. With our ASP.NET components, you have full control over the control's behavior via client functions.

Fast and Lightweight with XHTML Compliance

DevExpress controls are optimized for exceptional performance and efficient memory use without the loss of functionality or features. DevExpress ASP.NET controls also support optimizations like HTML compression, callbacks, image sprites, resource caching and sharing. Key ASP.NET controls in this subscription use semantic HTML to keep output clean and minimal. The semantic HTML markup means that web pages are lighter and faster, more search engine friendly and provide improved accessibility for screen readers.

Straightforward Localization

All DevExpress ASP.NET AJAX Controls can be easily localized using satellite resource assemblies. DevExpress delivers satellite assemblies for a large variety of languages and cultures. To make it easy to get started, resource files for three cultures are included to our installation: German, Japanese, and Spanish. If you need to modify our shipping resources or create satellite assemblies for a different language, simply use our Online Localization Service, a free tool for our active ASP.NET subscribers.
