UI Modules and Injection

The FileManager requires specific modules to be injected for different features:

Available Modules

Module Purpose Import
Toolbar Display toolbar with actions @syncfusion/ej2-filemanager
NavigationPane Left navigation tree @syncfusion/ej2-filemanager
DetailsView Grid-based file listing @syncfusion/ej2-filemanager

Module Injection Examples

import { FileManager, Toolbar, NavigationPane, DetailsView} from '@syncfusion/ej2-filemanager';

// Inject all modules
FileManager.Inject(Toolbar, NavigationPane, DetailsView);

// Now all features are available
const filemanager = new FileManager({
    view: 'LargeIcons', 
    ajaxSettings: { /* ... */ }
});

Common Patterns and Scenarios

Pattern 1: File Upload with Progress and Validation

const filemanager = new FileManager({
    ajaxSettings: {
        url: 'https://api.example.com/api/FileManager/FileOperations',
        uploadUrl: 'https://api.example.com/api/FileManager/Upload'
    },
    uploadSettings: {
        maxFileSize: 10485760,      // 10 MB
        minFileSize: 1024,          // 1 KB
        allowedExtensions: ['.pdf', '.doc', '.docx', '.xls', '.xlsx'],
        autoUpload: false           // Manual upload
    },
    uploading: (args) => {
        console.log('Upload progress:');
        args.fileData.forEach(file => {
            console.log(`  ${file.name}: ${file.size} bytes`);
        });
    },
    success: (args) => {
        if (args.action === 'upload') {
            console.log('Upload completed successfully');
        }
    },
    failure: (args) => {
        console.error('Upload failed:', args.error);
    }
});

filemanager.appendTo('#filemanager');

Pattern 2: Custom Context Menu with Validation

const filemanager = new FileManager({
    ajaxSettings: {
        url: 'https://api.example.com/api/FileManager/FileOperations'
    },
    contextMenuSettings: {
        file: ['Open', 'Cut', 'Copy', 'Delete', '|', 'Rename', 'Details'],
        folder: ['Open', 'Cut', 'Copy', 'Paste', '|', 'Delete', 'Rename'],
        layout: ['Refresh', 'NewFolder', 'Paste', '|', 'SortBy', 'View']
    },
    menuClick: (args) => {
        if (args.item.text === 'Delete') {
            const confirmed = confirm(`Delete "${args.fileDetails.name}"?`);
            if (!confirmed) {
                args.cancel = true;
            }
        }
    }
});

filemanager.appendTo('#filemanager');

Pattern 3: Multi-Select with Bulk Operations

const filemanager = new FileManager({
    ajaxSettings: {
        url: 'https://api.example.com/api/FileManager/FileOperations'
    },
    allowMultiSelection: true,
    enableRangeSelection: true,
    fileSelect: (args) => {
        const selectedFiles = filemanager.getSelectedFiles();
        console.log(`${selectedFiles.length} files selected`);
        
        // Update bulk action buttons
        updateBulkActionButtons(selectedFiles.length > 0);
    }
});

function bulkDownload() {
    const selected = filemanager.getSelectedFiles();
    if (selected.length > 0) {
        filemanager.downloadFiles();  // Downloads selected files
    }
}

function bulkDelete() {
    const selected = filemanager.getSelectedFiles();
    if (selected.length > 0 && confirm(`Delete ${selected.length} files?`)) {
        filemanager.deleteFiles();  // Deletes selected files
    }
}

filemanager.appendTo('#filemanager');

Pattern 4: Drag-and-Drop with Custom Handling

const filemanager = new FileManager({
    ajaxSettings: {
        url: 'https://api.example.com/api/FileManager/FileOperations'
    },
    allowDragAndDrop: true,
    fileDragStart: (args) => {
        console.log('Starting drag operation for:', args.fileDetails.length, 'items');
    },
    fileDragging: (args) => {
        // Check if drop target is valid during dragging
        const isValidTarget = args.target?.classList?.contains('drop-zone');
        if (!isValidTarget) {
            args.element.style.opacity = '0.5';  // Visual feedback
        }
    },
    fileDragStop: (args) => {
        // Perform validation before drop
        console.log('About to drop on:', args.target.id);
    },
    fileDropped: (args) => {
        // Called after successful drop
        const files = args.fileDetails.map(f => f.name);
        console.log('Files dropped successfully:', files);
    }
});

filemanager.appendTo('#filemanager');

Pattern 5: Localization and RTL Support

const filemanager = new FileManager({
    ajaxSettings: {
        url: 'https://api.example.com/api/FileManager/FileOperations'
    },
    locale: 'ar-AE',                    // Arabic (e.g., ar-AE, fr-FR, de-DE)
    enableRtl: true,                    // Right-to-Left rendering
    enablePersistence: true,            // Remember user settings
    cssClass: 'rtl-theme'              // Apply RTL-specific styles
});

// To change language at runtime
function changeLanguage(languageCode) {
    // Destroy current instance
    filemanager.destroy();
    
    // Create new instance with different locale
    const newFileManager = new FileManager({
        locale: languageCode,
        enableRtl: true,
        ajaxSettings: {
            url: 'https://api.example.com/api/FileManager/FileOperations'
        }
    });
    
    newFileManager.appendTo('#filemanager');
}

filemanager.appendTo('#filemanager');

Pattern 6: Access Control and Permissions

const filemanager = new FileManager({
    ajaxSettings: {
        url: 'https://api.example.com/api/FileManager/FileOperations',
        beforeSend: (args) => {
            // Add user token for authorization
            args.headers = {
                'Authorization': 'Bearer ' + getUserToken()
            };
        }
    },
    toolbarSettings: {
        items: ['NewFolder', 'Upload', 'Download', 'Delete', 'Refresh']
    },
    menuClick: (args) => {
        // Check permissions before allowing delete
        if (args.item.text === 'Delete' && !userHasPermission('delete')) {
            alert('You do not have permission to delete files');
            args.cancel = true;
        }
    }
});

filemanager.appendTo('#filemanager');

Pattern 7: Comprehensive File System Data Structure

Complete real-world example with multiple file types, nested folders, and optional properties:

import { FileManager, Toolbar, NavigationPane, DetailsView, LargeIconsView, ContextMenu } from '@syncfusion/ej2-filemanager';

FileManager.Inject(Toolbar, NavigationPane, DetailsView, LargeIconsView, ContextMenu);

// Complete file system data with 19 items showing various scenarios
const fileSystemData = [

Advanced Integration

Custom File Provider Integration

class CustomFileProvider {
    async readDirectory(path: string): Promise<any[]> {
        const response = await fetch(`/api/files?path=${path}`);
        return response.json();
    }
    
    async uploadFile(file: File, path: string): Promise<void> {
        const formData = new FormData();
        formData.append('file', file);
        formData.append('path', path);
        await fetch('/api/upload', { method: 'POST', body: formData });
    }
}

const provider = new CustomFileProvider();

const filemanager = new FileManager({
    ajaxSettings: {
        url: '/api/filemanager/operations'
    }
});

filemanager.appendTo('#filemanager');

State Persistence

const filemanager = new FileManager({
    enablePersistence: true,  // Automatically saves:
                              // - Current view (LargeIcons/Details)
                              // - Current path
                              // - Selected items
    
    // Optional: Manual state management
    beforeUnload: () => {
        const state = {
            path: filemanager.path,
            view: filemanager.view,
            selected: filemanager.getSelectedFiles()
        };
        localStorage.setItem('fm-state', JSON.stringify(state));
    }
});

filemanager.appendTo('#filemanager');

Virtual Scrolling for Large Lists

const filemanager = new FileManager({
    ajaxSettings: {
        url: 'https://api.example.com/api/FileManager/FileOperations'
    },
    enableVirtualization: true,         // Enable virtual scrolling
    view: 'Details',                    // Works best with Details view
    height: '500px'                     // Fixed height required
});

filemanager.appendTo('#filemanager');
