Add and remove list items from listview in EJ2 TypeScript Listview control

8 Aug 20235 minutes to read

You can add or remove list items from the ListView control using the addItem and removeItem methods. Refer to the following steps to add or remove a list item.

  • Render the ListView with data source, and use the template property to append the delete icon for each list item. Also, bind the click event for the delete icon using the actionComplete handler.

  • Render the Add Item button, and bind the click event. On the click event handler, pass data with random id to the addItem method to add a new list item on clicking the Add Item button.

  • Bind the click handler to the delete icon created in step 1. Within the click event, remove the list item by passing the delete icon list item to removeItem method.

import { ListView } from "@syncfusion/ej2-lists";
import { Button } from "@syncfusion/ej2-buttons";
import { MouseEventArgs } from "@syncfusion/ej2-base";

//Define an array of JSON data
let data: { [key: string]: Object }[] = [
    { text: "Hennessey Venom", id: "1", icon: "delete-icon" },
    { text: "Bugatti Chiron", id: "2", icon: "delete-icon" },
    { text: "Bugatti Veyron Super Sport", id: "3", icon: "delete-icon" },
    { text: "Aston Martin One- 77", id: "4", icon: "delete-icon" },
    { text: "Jaguar XJ220", id: "list-5", icon: "delete-icon" },
    { text: "McLaren P1", id: "6", icon: "delete-icon" }

//Initialize the ListView control
let listviewInstance: ListView = new ListView({
    //Set the dataSource property
    dataSource: data,
    //Map the appropriate columns to the fields property
    fields: { text: "text", iconCss: "icon" },
    //Set the template for list items
    template: "<div class='text-content'> ${text} <span class = 'delete-icon'></span> </div>",
    //Event handler to bind the click event for delete icon
    actionComplete: onComplete
//Render the initialized ListView

//Initialize the Button control.
let button: Button = new Button();
//Render the initialized button

//Event handler to add the list item on button click
document.getElementById("btn").onclick = () => {
    let data: { [key: string]: Object } = {
        text: "Koenigsegg - " + (Math.random() * 1000).toFixed(0),
        id: (Math.random() * 1000).toFixed(0).toString(),
        icon: "delete-icon"

//Method for actionComplete handler
function onComplete() {
    let iconEle: HTMLCollection = document.getElementsByClassName("delete-icon");
    //Event handler to bind the click event for delete icon, (element: HTMLElement) => {
        element.addEventListener("click", deleteItem.bind(this));

//Method to delete the list item
function deleteItem(args: MouseEventArgs) {
    let liItem: HTMLElement = ( as HTMLElement).parentElement.parentElement;
