Features

Overview
RadUpload is a set of three controls for uploading files and monitoring the progress of uploads (or other long processes). These controls provide tight integration with ASP.NET AJAX. The Telerik ASP.NET AJAX Upload control contains:
- RadProgressManager – a non-visual element to manage the process of file uploads and progress monitoring.
- RadUpload – a control for single- and multi-file uploads, integrated file validation and more.
- RadProgressArea – a control for displaying progress dialogs: automatically monitoring file uploads and optionally monitoring any other measurable process on the server.

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:
- Uploading large files - You can upload files with a combined size of up to 2GB.
- Uploading multiple files - You can easily upload several files at once - just select the files in separate input areas and submit the form. Furthermore, you can manipulate the number of input areas and can add new ones on the client.
- Automatic file storing – RadUpload provides a property, which allows you to specify a folder where the files will be stored automatically. See demo
- Manipulating uploaded files – The server-side API provides a way to manipulate uploaded files (rename them, save them, etc). See demo

Monitoring Upload Progress
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 progress indicators, the count of uploaded files, the name of the file being currently uploaded, and the elapsed and the estimated times
- Progress templates – RadProgressArea allows you to customize its content and style through templates. 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, useful in case you have long forms with multiple submit buttons.
- Custom progress monitoring – RadProgressArea can be used separately from RadUpload and is able to monitor the progress of any measurable process.

Rich Client-side API

The Upload control for ASP.NET AJAX 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 RadUpload 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 is not hit as the page does not go through the complete page lifecycle as this is not needed. This significantly reduces the server load and data transfer.

File Validation
- Integrated validation – RadUpload can automatically validate the size, file extension and the MIME type of uploaded files against your preferences.
- Custom validation – In addition to the integrated validation, RadUpload lets you perform your own custom validation using the server-side ValidatingFile event. By using this event, you can define your own custom validation logic and override the integrated validation if needed.
- Client-side validation – RadUpload provides a client-side function, which validates file extensions on the client. The validation is done by integrating the RadUpload with a CustomValidator which will prevent the page from submitting when there are selected files with invalid extensions.
