About RadFileExplorer for ASP.NET AJAX

Bringing desktop to the web is not mythical and Telerik File Explorer component is yet another proof. A flexible web control for file management, RadFileExplorer completely mimics the Windows Explorer functionality and is entirely built with the Telerik controls. You can easily add it to your page, and organize your files and folders: create, rename, delete, drag and drop, all the familiar file operations and all of them performed on the client.

RadFileExplorer and 80+ other controls are part of UI for ASP.NET AJAX, a comprehensive toolset taking care of the common functionality of your application, while leaving you with more time to work on its business logic.

Get Started

  • Use Telerik’s Visual Studio Extensions (which you have installed together with the Telerik controls) to quickly create, upgrade and configure your Telerik UI projects. Save time by using the ready-to-use Visual Studio templates that cover common application scenarios.
  • Find the controls in need in your VS toolbox and use the Design-time surface and rich wizards to configure them quickly.
  • If you’d like to learn more about how to best implement the controls, browse the Telerik folder in your Start menu and use the shortcuts there to access the local demos, online documentation or open the sample examples app in Visual Studio.
  • If you like this particular FileExplorer demo, you can use the following path to find it in the sample website application:
