JavaScript/jQuery FileManager - Web API
The Web API file provider works with a file system located on the server.
Set the endpointUrl option 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 options: nameExpr, sizeExpr, dateModifiedExpr, and so on.
The following code shows how to bind the FileManager to the Web API file provider:
jQuery
$(function() { $("fileManagerContainer").dxFileManager({ fileProvider: new DevExpress.FileProviders.WebApi({ endpointUrl: "https://mydomain.com/api/files", thumbnailExpr: "icon", // ... }) }); });
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:
