Angular 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:
- <dx-file-manager id="fileManager"
- [fileSystemProvider]="remoteFileProvider">
- <!-- ... -->
- </dx-file-manager>
- import { Component } from '@angular/core';
- import RemoteFileSystemProvider from 'devextreme/file_management/remote_provider';
- @Component({
- selector: 'app-root',
- templateUrl: 'app/app.component.html',
- styleUrls: ['app/app.component.css']
- })
- export class AppComponent {
- remoteFileProvider: RemoteFileSystemProvider;
- constructor() {
- this.remoteFileProvider = new RemoteFileSystemProvider({
- endpointUrl: "https://js.devexpress.com/Demos/Mvc/api/file-manager-file-system-scripts"
- });
- }
- }
- import { BrowserModule } from '@angular/platform-browser';
- import { NgModule} from '@angular/core';
- import { AppComponent } from './app.component';
- import { DxFileManagerModule } from 'devextreme-angular';
- @NgModule({
- imports: [
- BrowserModule,
- DxFileManagerModule
- ],
- declarations: [AppComponent],
- bootstrap: [AppComponent]
- })
- export class AppModule { }
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:
