accessKey
The value of this property will be passed to the accesskey
attribute of the HTML element that underlies the UI component.
allowedFileExtensions
The FileManager UI component cannot upload a file and displays an error message when the file's extension is not allowed.
jQuery
$(function () { $("#file-manager").dxFileManager({ allowedFileExtensions: [".js", ".json", ".css"] // ... }); });
currentPath
jQuery
$(function () { $("#file-manager").dxFileManager({ currentPath: "Documents/Images" // ... }); });
currentPathKeys
Each path part has each own key. For example, path "folder1/folder2" has two parts: 'folder1' with the 'f1' key and folder2 with the 'f2' key. To open this location, assign the ["f1","f2"] array of strings to the currentPathKeys property value.
jQuery
$(function () { $("#file-manager").dxFileManager({ currentPathKeys: ["EB458000-0341-6943", "92F5-4722-A7D6-98EB"] // ... }); });

jQuery
$(function() { $("#fileManagerContainer").dxFileManager({ // ... customizeDetailColumns: function(columns) { // ... // Customize the "columns" array objects here // ... return columns; } }); });
Angular
<dx-file-manager ... [customizeDetailColumns]="fileManager_customizeDetailColumns"> </dx-file-manager>
import { Component } from '@angular/core'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { // Uncomment the following lines if the function should be executed in the component's context // constructor() { // this.fileManager_customizeDetailColumns = this.fileManager_customizeDetailColumns.bind(this); // } fileManager_customizeDetailColumns(columns) { // ... // Customize the "columns" array objects here // ... return columns; } }
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 ], providers: [], bootstrap: [AppComponent] }) export class AppModule { }
Vue
<template> <DxFileManager ... :customize-detail-columns="fileManager_customizeDetailColumns" /> </template> <script> import 'devextreme/dist/css/dx.common.css'; import 'devextreme/dist/css/dx.light.css'; import DxFileManager from 'devextreme-vue/file-manager'; export default { components: { DxFileManager }, methods: { fileManager_customizeDetailColumns(columns) { // ... // Customize the "columns" array objects here // ... return columns; } } } </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.common.css'; import 'devextreme/dist/css/dx.light.css'; import FileManager from 'devextreme-react/file-manager'; class App extends React.Component { // Uncomment the following lines if the function should be executed in the component's context // constructor(props) { // super(props); // this.fileManager_customizeDetailColumns = this.fileManager_customizeDetailColumns.bind(this); // } fileManager_customizeDetailColumns(columns) { // ... // Customize the "columns" array objects here // ... return columns; } render() { return ( <FileManager ... customizeDetailColumns={this.fileManager_customizeDetailColumns} /> ); } } export default App;
customizeThumbnail
This function should return one of the following:
- The icon's URL
- The icon's name if the icon is from the DevExtreme icon library
- The icon's CSS class if the icon is from an external icon library (see External Icon Libraries)
- The icon in the Base64 format
elementAttr
Specifies the global attributes to be attached to the UI component's container element.
jQuery
$(function(){ $("#fileManagerContainer").dxFileManager({ // ... elementAttr: { id: "elementId", class: "class-name" } }); });
Angular
<dx-file-manager ... [elementAttr]="{ id: 'elementId', class: 'class-name' }"> </dx-file-manager>
import { DxFileManagerModule } from "devextreme-angular"; // ... export class AppComponent { // ... } @NgModule({ imports: [ // ... DxFileManagerModule ], // ... })
Vue
<template> <DxFileManager ... :element-attr="fileManagerAttributes"> </DxFileManager> </template> <script> import DxFileManager from 'devextreme-vue/file-manager'; export default { components: { DxFileManager }, data() { return { fileManagerAttributes: { id: 'elementId', class: 'class-name' } } } } </script>
React
import React from 'react'; import FileManager from 'devextreme-react/file-manager'; class App extends React.Component { fileManagerAttributes = { id: 'elementId', class: 'class-name' } render() { return ( <FileManager ... elementAttr={this.fileManagerAttributes}> </FileManager> ); } } export default App;
fileSystemProvider
File system providers are components that provide APIs used to access and modify virtual file systems.
The following example illustrates how to configure an 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 }, //... ], }, { name: "Images", isDirectory: true, items: [ { name: "logo.png", isDirectory: false, size: 20480 }, { name: "banner.gif", isDirectory: false, size: 10240 } ] }, //... ];
