You can also manually close the Dialogs by creating an instance to the dialog and call the hide method.
Below sample demonstrates the different ways of hiding the utility dialog.
import { DialogUtility } from '@syncfusion/ej2-popups';
import * as React from "react";
import './App.css';
const DialogObj;
class App extends React.Component<{}, {}> {
public buttonClick(): void {
DialogObj = DialogUtility.confirm({
animationSettings: { effect: 'Zoom' },
cancelButton: { text: 'Cancel', click: this.cancelClick.bind(this) },
closeOnEscape: true,
content: "This is a Confirmation Dialog!",
okButton: { text: 'OK', click: this.okClick.bind(this) },
showCloseIcon: true,
title: ' Confirmation Dialog',
});
}
public okClick(): void {
alert('you clicked OK button');
}
public cancelClick(): void {
//Hide the dialog
DialogObj.hide();
}
public render() {
return (
