Uploading Files
You can use the RadUpload and RadProgressManager components, separately or together, to enhance your application's ability to upload files. Some of the upload capabilities include:
- Multi-file Upload - You can easily upload several files at once - just select the files and submit the form. Furthermore, depending on the file-count settings, users can add client-side extra file selectors (inputs) if needed. This behavior is controlled using the InitialFileInputsCount and MaxFileInputsCount properties.
- Uploading Large Files - You can upload files with a combined size of up to 2GB, but it requires some modifications in your application configuration files.
- Automatic Storing of Files - RadUpload provides a TargetFolder property, which allows you to specify the folder where the files will be stored after upload.

Progress Areas
RadProgressArea automatically displays a progress dialog when files are uploaded. In addition, you can use it as a progress dialog for any other long process by supplying custom progress information using the server-side API. The progress area features:
- Status information - includes progress bar and count for the uploaded bytes; the name of the file being currently uploaded; the elapsed and the estimated times
- Custom progress with templates – RadProgressArea allows you to customize its content and style through templates. For example you can rearrange the progress elements or create your own progress bar.
See demo
- Multiple progress areas - The developers can now put any number of progress areas on a page. This is very useful in case you have long forms with multiple submit buttons. By placing multiple progress areas on the page you can ensure that at least one of them will be visible when the page is submitted.
- Support for <input type=file> elements - RadProgressArea can be used with the standard <input type=file> elements without the presence of RadUpload on the page. Developers may find this scenario useful when they want to create a completely custom upload form user interface.

Rich Client-side API and Events

Telerik ASP.NET Upload control provides a flexible client-side API. You can easily interact with the RadUpload, RadProgressManager and RadProgressArea objects in the browser using their client-side objects. In addition to a variety of client-side events, the client-side object model lets you achieve tasks while avoiding the post-backs that would trigger file uploading.

Server-side API

If you need to perform additional actions on uploaded files before saving them (for example, if you are using custom fields), or if you want to manipulate them in memory without saving them, you can use Telerik ASP.NET Upload server-side API. You can use the server-side API to rename uploaded files or save them into a database, or other storage medium.

Reduced Server Load

The Telerik ASP.NET Upload control now features a new HttpHandler specially designed for monitoring the process and updating its progress. As a result upon a request for progress update the server does not pass through the complete page lifecycle as this is not needed. This significantly reduces the server load and data transfer.

Automatic File Validation
- Automatic - the Telerik ASP.NET AJAX Upload control can automatically validate the size, extension and the MIME type of the uploaded files. The valid files can be accessed using the UploadedFiles property of the RadUpload instance. The invalid files are still uploaded on the server and can be accessed using the InvalidFiles property if necessary. See online demo.
- Custom - In addition to the automatic validation, the Telerik ASP.NET AJAX Upload lets you perform your own custom validation using the server-side ValidatingFile event. By using this event, you can use your own custom validation logic and override the integrated validation if needed.
