File Manager

Entity Framework ORM

The File Manager widget allows you to manage file system items that use the Entity Framework ORM to link to a database. You can use the Remote File Provider to connect to the file system on the client side. To process the widget's HTTP requests on the server, create your own file provider, which implements the IFileProvider interface.
