Angular FileManager - Object
The Object file system provider works with a file system represented by an in-memory array of JSON objects.
Assign the array to the data property. Data object fields should have conventional names listed in the data description. Otherwise, specify [fieldName]Expr properties: nameExpr, sizeExpr, dateModifiedExpr, and so on.
The following code shows how to bind the FileManager to the Object file system provider:
jQuery
$(function() { $("#file-manager").dxFileManager({ fileSystemProvider: fileSystem, // ... }); });
var fileSystem = [ { name: "Documents", isDirectory: true, items: [{ name: "Projects", isDirectory: true, items: [{ name: "About.rtf", isDirectory: false, size: 1024 }, { name: "Passwords.rtf", isDirectory: false, size: 2048 }] }, { name: "About.xml", isDirectory: false, size: 1024 }] }];
Angular
<dx-file-manager id="fileManager" [fileSystemProvider]="fileItems"> </dx-file-manager>
import { Component } from '@angular/core'; import ObjectFileSystemProvider from 'devextreme/file_management/object_provider'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { fileItems = [{ name: "Documents", isDirectory: true, items: [{ name: "Projects", isDirectory: true, items: [{ name: "About.rtf", isDirectory: false, size: 1024 }, { name: "Passwords.rtf", isDirectory: false, size: 2048 }] },{ name: "About.xml", isDirectory: false, size: 1024 }] }]; }
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 { }
