React FileManager Props
This section describes properties that configure the FileManager UI component's contents, behavior, and appearance.
accessKey
The value of this property will be passed to the accesskey
attribute of the HTML element that underlies the UI component.
activeStateEnabled
The UI component switches to the active state when users press down the primary mouse button. When this property is set to true, the CSS rules for the active state apply. You can change these rules to customize the component.
Use this property when you display the component on a platform whose guidelines include the active state change for UI components.
allowedFileExtensions
The FileManager UI component cannot upload a file and displays an error message when the file's extension is not allowed.

toolbar
The FileManager UI component allows you to add default and custom toolbar items.
Predefined Items
Predefined toolbar items include:
- 'showNavPane' - Shows or hides the navigation panel.
- 'create' - Creates a new directory.
- 'upload' - Uploads a file.
- 'refresh' - Refreshes the file manager content and shows the progress panel.

- 'move' - Moves files and directories.
- 'copy' - Copies files and directories.
- 'rename' - Renames files and directories.
- 'delete' - Deletes files and directories.
- 'switchView' - Switches between the 'Details' and 'Thumbnails' file system representation modes.
- 'clearSelection' - Clears selection from files and directories in the Item View area.
To add a predefined item to the toolbar, specify its name and optional settings ('visible', 'location', 'locateInMenu', 'text', 'icon', 'disabled') and add the item to one of the following collections:
items - Displays toolbar items when no file system item is selected.
fileSelectionItems - Displays toolbar items when one or more file system items are selected.
- import React from 'react';
- import 'devextreme/dist/css/dx.light.css';
- import FileManager, { Toolbar, Item, FileSelectionItem } from 'devextreme-react/file-manager';
- class App extends React.Component {
- render() {
- return (
- <FileManager>
- <Toolbar>
- {/* Specifies a predefined item's name and optional settings */}
- <Item name="create" text="Create a directory" icon="newfolder" />
- {/* Specifies a predefined item's name only */}
- <Item name="switchView" />
- <Item name="separator" />
- {/* Specifies items that are visible when users select files */}
- <FileSelectionItem name="copy" />
- <FileSelectionItem name="rename" />
- </Toolbar>
- </FileManager>
- );
- }
- }
- export default App;
Custom Items
To add a custom toolbar item, specify its text and optional settings (for example, a file extension for the toolbar item that creates a new file) and add the item to one of the following collections:
items - Displays toolbar items when no file system item is selected.
fileSelectionItems - Displays toolbar items when one or more file system items are selected.
The widget property allows you to specify a UI component for a custom toolbar item (dxButton is the default UI component). Use the toolbarItemClick event to handle clicks on custom toolbar items.
- import React from 'react';
- import 'devextreme/dist/css/dx.light.css';
- import FileManager, { Toolbar, Item } from 'devextreme-react/file-manager';
- const App = () => {
- const fileMenuOptions = {
- items: [
- {

- icon: 'plus',
- items: [
- {
- text: 'Text Document',
- extension: '.txt'
- },
- {
- text: 'RTF Document',
- extension: '.rtf'
- },
- {
- text: 'Spreadsheet',
- extension: '.xls'
- }
- ]
- }
- ],
- onItemClick: 'onItemClick'
- };
- const onItemClick = (e) => {
- // ...
- };
- return (
- <FileManager>
- <Toolbar>
- <Item widget="dxMenu" options={this.fileMenuOptions} />
- </Toolbar>
- </FileManager>
- );
- };
- export default App;

- return (
- <FileManager>
