Use Telerik Async Upload to perform painless ASP.NET uploads of single and multiple files. RadAsyncUpload uses of the File API to natively upload files without using plug-ins and has a graceful downgrade to Flash/Silverlight where the latter is not available.
With our best-of-breed ASP.NET file upload, you can take advantage of the codeless progress monitoring, which shows a nice inline progress indicator next to each file being uploaded.
In advanced scenarios you may consider using RadProgressArea, a control that can be easily integrated with RadAsyncUpload. ProgressArea is easier to customize thanks to its 20+ built-in skins and support for templates, as well as its localization capabilities.
Leverage the latest technology trends with Telerik Async File Upload in ASP.NET – RadAsyncUpload will enable your end users to upload files using drag and drop functionality. You can either allow them to drop the desired files over the upload or define custom drop zones over the page. All of this is achieved codelessly.
Make use of the rich UI that shows visual notifications for the common operations: successful upload, failed validation and upload in progress. Complement that with the beautiful cancel upload button.
The control allows you to persist uploaded files between postbacks and only sends them to the server when needed.
Utilize the integrated chunk by chunk upload mechanism in order to work around the integrated ASP.NET maximum upload size of 4 MB. The control uploads files by dividing them into chunks, each 2 MB big.
Utilize the codeless client validation that validates both against file size and extension. And to make double sure that no invalid file gets through, there is a server-side counterpart that will catch any malicious attempt.
Easily customize the way you handle file uploads. Choose betweenmanual or automatic upload, add additional fields to the files that are submitted to the server, or write your own custom handler to deal with the uploaded files as you please.
Telerik Async Upload control was built for compliance with major accessibility standards, such as W3C Web Content Accessibility Guidelines 1.0/2.0 and Section 508 of the Rehabilitation Act. Set the direction attribute to “rtl” to make your RadAsyncUpload work in a right-to-left mode. For international applications, use global or local resources to completely localize it.
