Adding a custom item to the context menu in EJ2 TypeScript File Manager control

3 Mar 20255 minutes to read

The context menu can be customized using the contextMenuSettings, menuOpen, and menuClick events.

The following example shows how to add a custom item to the context menu.

The contextMenuSettings property is used to add a new menu item. The menuOpen event is used to add an icon to the new menu item. The menuClick event is used to add an event handler to the new menu item.

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

FileManager.Inject(Toolbar, NavigationPane, DetailsView)

let hostUrl: string = 'https://ej2-aspcore-service.azurewebsites.net/';
// initialize File Manager control and add custom item to contextmenu
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'
    },
    // Custom menu item added to context menu
    contextMenuSettings: {
        file: ["Custom", "Open", "|", "Delete", "Download", "Rename", "|", "Details"],
        folder: ["Custom", "Open", "|", "Delete", "Download", "Rename", "|", "Details"],
        layout: ["Custom", "SortBy", "View", "Refresh", "|", "NewFolder", "Upload", "|", "Details", "|", "SelectAll"],
        visible: true
    },
    menuOpen: menuOpen,
    menuClick: menuClick,
    height: '380px'
});

// Icon added to custom menu item
function menuOpen(args: MenuOpenEventArgs) {
    for (let i: number = 0; i < args.items.length; i++) {
        if (args.items[i].id === this.element.id + '_cm_custom') {
            args.items[i].iconCss = 'e-icons e-fe-tick';
        }
    }
}

// event for custom menu item
function menuClick(args: MenuClickEventArgs) {
    if (args.item.text === 'Custom') {
        alert('You have clicked custom menu item')
    }
}

// render initialized File Manager
filemanagerInstance.appendTo('#filemanager');
