Disable keyboard interactions in EJ2 TypeScript FileManager component

26 Oct 20243 minutes to read

The FileManager component supports keyboard shortcuts as default. If you wish to disable keyboard interactions, you can do so by utilizing the keyup event for the specific views (large icons, details) of the FileManager component and applying the keyboard prevention method. This approach will effectively disable all keyboard interactions within the FileManager component, including the left and right arrow keys.

The following example demonstrates how to prevent the keyboard interaction for the LargeIconsView and DetailsView.

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

FileManager.Inject(Toolbar, NavigationPane, DetailsView)

let hostUrl: string = 'https://ej2-aspcore-service.azurewebsites.net/';
// initialize File Manager component
let filemanagerInstance: FileManager = new FileManager({
    ajaxSettings: {
        url: hostUrl + 'api/FileManager/FileOperations',
        getImageUrl: hostUrl + 'api/FileManager/GetImage',
        uploadUrl: hostUrl + 'api/FileManager/Upload',
        downloadUrl: hostUrl + 'api/FileManager/Download'
    },
    created: () => {
        var largeicon_view = document.getElementById('filemanager_largeicons');
        var details_view = document.getElementById('filemanager_grid');
        //Bind keyup event for both LargeIcons and Details view.
        largeicon_view?.addEventListener('keyup', keyUpHandler);
        details_view?.addEventListener('keyup', keyUpHandler);
    }
});
// render initialized FileManager
filemanagerInstance.appendTo('#filemanager');

function keyUpHandler(event) {
    //Prevent all the keyboard interactions.
    event.preventDefault();
    event.stopPropagation();
    event.stopImmediatePropagation();
}
