Set the placeholder in React Datetimepicker component

The placeholder property displays hint text in the DateTimePicker input field when it is empty. This helps guide users on the expected date and time format or input requirement.

The following example demonstrates how to set a custom placeholder in the DateTimePicker component:

index.jsx

import { DateTimePickerComponent } from '@syncfusion/ej2-react-calendars';
import * as React from 'react';
import * as ReactDOM from 'react-dom';
export default class App extends React.Component {
    render() {
        return <DateTimePickerComponent id="datetimepicker" placeholder='Select a date and time'/>;
    }
}
ReactDOM.render(<App />, document.getElementById('element'));

index.tsx

import { DateTimePickerComponent } from '@syncfusion/ej2-react-calendars';
import * as React from 'react';
import * as ReactDOM from 'react-dom';

export default class App extends React.Component<{}, {}> {
    public render() {
        return <DateTimePickerComponent id="datetimepicker" placeholder='Select a date and time' />;
    }
}
ReactDOM.render(<App />, document.getElementById('element'));
