Open DatePicker popup on input focus in React Datepicker component

18 Nov 20182 minutes to read

The DatePicker popup can be programmatically opened when the input element receives focus by calling the show method within the input’s focus event handler. This approach improves user experience by immediately displaying the calendar when users interact with the input field.

The following example demonstrates opening the DatePicker popup automatically when the input field receives focus:

index.jsx

// import the datepickercomponent
import { DatePickerComponent } from '@syncfusion/ej2-react-calendars';
import * as React from 'react';
import * as ReactDOM from 'react-dom';
export default class App extends React.Component {
    onFocus(args) {
        this.dateObj.show();
    }
    render() {
        return (
        // Specifies the tag for render the DatePicker component
        <DatePickerComponent focus={this.onFocus.bind(this)} placeholder="Choose a date" ref={scope => { this.dateObj = scope; }}/>);
    }
}
ReactDOM.render(<App />, document.getElementById('element'));

index.tsx

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

export default class App extends React.Component<{}, {}> {

    public onFocus(args: FocusEventArgs){
        this.dateObj.show();
    }

    public render() {
        return (
            // Specifies the tag for render the DatePicker component
            <DatePickerComponent focus={this.onFocus.bind(this)} placeholder="Choose a date" ref = {scope => {this.dateObj = scope }}/>
        );
     }
 }

ReactDOM.render(<App />, document.getElementById('element'));
