Angular FileManager - Custom
Use the custom provider's methods to handle file operations (add, delete, rename, and so on).
The following code shows how to create a custom file system provider and bind the FileManager UI component to it:
- <dx-file-manager
- [fileSystemProvider]="fileSystemProvider">
- </dx-file-manager>
- import { Component } from '@angular/core';
- import CustomFileSystemProvider from 'devextreme/file_management/custom_provider';
- @Component({
- selector: 'app-root',
- templateUrl: './app.component.html',
- styleUrls: ['./app.component.css']
- })
- export class AppComponent {
- fileSystemProvider: CustomFileSystemProvider;
- constructor(http: HttpClient) {
- this.fileSystemProvider = new CustomFileSystemProvider({
- getItems,
- createDirectory,
- renameItem,
- deleteItem,
- // ...
- });
- }
- }
- function getItems(parentDirectory) {
- // ...
- }
- // other functions
- import { BrowserModule } from '@angular/platform-browser';
- import { NgModule } from '@angular/core';
- import { AppComponent } from './app.component';
- import { DxFileManagerModule } from 'devextreme-angular';
- @NgModule({
- declarations: [
- AppComponent
- ],
- imports: [
- BrowserModule,
- DxFileManagerModule
- ],
- //...
- })
- export class AppModule { }
