Telerik RadUpload by Telerik

Add file upload functionality to your ASP.NET applications. Telerik RadUpload is a specialized file-upload component, employing a highly efficient proprietary HttpModule. The product allocates a minimum amount of server memory, while enabling optimized and completely configurable single and multi-file uploads. RadUpload features an efficient proprietary HttpModule. RadUpload processes the upload stream in variable size chunks. The files are constructed in temporary folders on the server, which ultimately reduces the amount of allocated memory to a minimum.

Optimized Memory Usage - RadUpload features a highly efficient proprietary HttpModule. Unlike the standard upload mechanism, which puts all of the uploaded files in the server memory, RadUpload processes the upload stream in chunks with a variable size. The files are constructed in temporary folders on the server, which ultimately reduces the amount of allocated memory to a minimum.

Support for <input type=file> elements - RadProgressArea can now 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.

Automatic File Validation - RadUpload 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.

Automatic Storing of Files - RadUpload provides a TargetFolder property, which allows you to specify the folder where the files will be stored after upload.

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.

Customizable Appearance - The appearance of RadUpload can be easily customized using skins. The visibility of the user interface elements can be controlled using the ControlObjectsVisibility property.

Customizable Progress Area - Displays various information about the status of the upload progress:

progress bar and count for the uploaded bytes

the name of the file being currently uploaded

progress bar and count for the uploaded files

the elapsed and the estimated times

Reduced server load - RadUpload features a 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.

RadProgressManager control - Used for monitoring the form submission progress and updating the progress areas on the page.

Monitor any measurable server process Thanks to the RadProgressManager you can use the progress area to monitor not only file uploads but also any time consuming tasks on the server such as heavy calculations, database queries, etc.

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.

Rich client-side API - Both RadProgressArea and RadProgressManager provide rich API for client-side customization (OnClientAdding, OnClientDeleting, OnClientClearing, OnClientFileSelected, OnClientDeletingSelected).

Custom progress areas with templates - RadProgressArea contains a ProgressTemplate property, which can be used to fully customize its content and style. For example you can rearrange the progress elements or create your own progress bar.
