Multiple selection in React File manager component

19 Sep 20248 minutes to read

The file manager allows you to select multiple files by enabling the allowMultiSelection property (enabled by default). The multiple selection can be done by pressing the Ctrl key or Shift key and selecting the files. The check box can also be used to do multiple selection. Ctrl + A can be used to select all files in the current directory. The fileSelect event will be triggered when the items of file manager control is selected or unselected.

app.jsx

import { DetailsView, FileManagerComponent, NavigationPane, Toolbar, Inject } from '@syncfusion/ej2-react-filemanager';
import * as React from 'react';
function App() {
    let hostUrl = "https://ej2-aspcore-service.azurewebsites.net/";
    function onFileSelect(args) {
        console.log(args.fileDetails.name + " has been " + args.action + "ed");
    }
    return (<div className="control-section">
        <FileManagerComponent id="file" view="Details" allowMultiSelection={true} ajaxSettings={{
            downloadUrl: hostUrl + 'api/FileManager/Download',
            getImageUrl: hostUrl + "api/FileManager/GetImage",
            uploadUrl: hostUrl + 'api/FileManager/Upload',
            url: hostUrl + "api/FileManager/FileOperations"
        }} fileSelect={onFileSelect.bind(this)}>
            <Inject services={[NavigationPane, DetailsView, Toolbar]}/>
          </FileManagerComponent>

Note: The File Manager has support to select files and folders initially or dynamically by specifying their names in selectedItems property.

Range Selection

The File Manager supports for selecting files and folders in specific ranges through mouse drag as like File Explorer. This is particularly useful in scenarios where users need to select a large group of files quickly without manually clicking each one.

Enabling Range Selection

To enable range selection, you need to set the enableRangeSelection property to true and ensure that multi-selection is allowed using the allowMultiSelection property.

import { DetailsView, FileManagerComponent, NavigationPane, Toolbar, Inject } from '@syncfusion/ej2-react-filemanager';
import * as React from 'react';
function App() {

    function onFileSelect(args) {
        console.log(args.fileDetails.name + " has been " + args.action + "ed");
    }
    return (<div className="control-section">
        <FileManagerComponent id="file" view="Details" allowMultiSelection={true} enableRangeSelection={true} ajaxSettings={{
            downloadUrl: hostUrl + 'api/FileManager/Download',
            getImageUrl: hostUrl + "api/FileManager/GetImage",
            uploadUrl: hostUrl + 'api/FileManager/Upload',

        }} fileSelect={onFileSelect.bind(this)}>
