Preventing Popups When Using Dropdown Button with ListView

Introduction

When integrating a dropdown button with a list view in your web application, you might encounter unwanted pop-ups that can affect the user experience.This article provides a solution to prevent these pop-ups by handling the “beforeClose” event of the dropdown button component.

Handling the “beforeClose” Event

To avoid popups when a dropdown button is used alongside a list view, you can utilize the beforeClose event of the DropDownButtonComponent. This event is triggered before the popup is closed, allowing you to determine whether the popup should be closed or not based on specific conditions.

Here is an example of how to implement this in your code:

import { DropDownButtonComponent } from '@syncfusion/ej2-react-splitbuttons';

const YourComponent = () => {
    const onClose = (args) => {
        if (args.event.currentTarget.children[0].id === "listview") {
            args.cancel = true;
        }
    };

    return (
          <div className='control-pane'>
            <div className='control-section'>
              <div>
                <ListViewComponent id="listview" dataSource={"data"} fields={"field"} showCheckBox={"true"}/>
                <DropDownButtonComponent target='#listview' iconCss='e-icons e-down' cssClass='e-caret-hide' beforeClose={'onClose'}/>
              </div>
            </div>
         </div>
    );
};

In the onClose function, we check if the current target’s first child has an ID of “listview”. If it does, we set args.cancel to true, which prevents the popup from closing.
