jQuery FileManager - Remote
Set the endpointUrl property to specify the endpoint used to access and modify the file system.
The server should return data objects of the following structure:
{
name: "MyFile.jpg",
size: 1024,
dateModified: "2019/05/08",
thumbnail: "/thumbnails/images/jpeg.ico",
isDirectory: true,
hasSubDirectories: true
}Fields in this structure have conventional names that you can change via [fieldName]Expr properties: nameExpr, sizeExpr, dateModifiedExpr, and so on.
The following code shows how to bind the FileManager to the Remote file system provider:
jQuery
$(function () {
$("#file-manager").dxFileManager({
fileSystemProvider: new DevExpress.fileManagement.RemoteFileSystemProvider({
endpointUrl: "https://js.devexpress.com/Demos/Mvc/api/file-manager-file-system-scripts"
}),
// ...
});
});Angular

}On the server-side, you need to process file management requests. DevExtreme provides helpers for ASP.NET MVC and ASP.NET Core that do this. To view the server-side code, navigate to the FileManagerApiController.cs tab in the following demo:
