Add and remove list items from listview in React Listview component

30 Jan 20238 minutes to read

You can add or remove list items from the ListView component 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.
