How do I set the date format?

Use the formatString property: formatString = 'yyyy-MM-dd' for ISO format or 'MM/dd/yyyy' for US format.

How do I disable certain dates?

Use the disabledDates property with an array of dates or date ranges to prevent selection.

Getting Started with React DateTimePicker Component

Smart UI React targets React 18+ and current Node LTS for tooling; use TypeScript templates when you want typed props and events.

Demo source (Smart UI repo): react/source/datetimepicker/basic/App.jsx

1 Create a Vite + React + TypeScript app

npm create vite@latest my-smart-app -- --template react-ts

```
cd my-smart-app
```
then
```
npm install
```

2 Install Smart UI for React

npm install smart-webcomponents-react

3 Import styles and render the component

Open src/App.tsx (or App.jsx if you chose JavaScript). The snippet below matches Smart UI React demos for this widget:

import 'smart-webcomponents-react/source/styles/smart.default.css';
import './App.css';
import React from "react";
import ReactDOM from 'react-dom/client';
import { DateTimePicker } from 'smart-webcomponents-react/datetimepicker';

const App = () => {
	return (
		<div>
			<DateTimePicker calendarButton enableMouseWheelAction
				dropDownPosition="center-bottom" spinButtons spinButtonsPosition="left"></DateTimePicker>
		</div>
	);
}



export default App;

4 Run the dev server

npm run dev

Open the URL Vite prints (often http://localhost:5173/).

Alternative: Next.js

Create an app with npx create-next-app@latest (Pages Router or App Router). Install the same package (npm install smart-webcomponents-react), then reuse the imports and default export from step 3 in pages/_app.tsx, the App Router root app/layout.tsx, or your top-level layout component so styles and the widget tree load once.

Common Use Cases

Set date range

Configure min and max selectable dates

dateTimePicker.min = new Date(2026, 0, 1);
dateTimePicker.max = new Date(2026, 11, 31);

Format display

Customize the date format shown

dateTimePicker.formatString = 'yyyy-MM-dd HH:mm';

Troubleshooting

How do I set the date format?: Use the formatString property: formatString = 'yyyy-MM-dd' for ISO format or 'MM/dd/yyyy' for US format.
How do I disable certain dates?: Use the disabledDates property with an array of dates or date ranges to prevent selection.

TypeScript Support

Types ship with smart-webcomponents-react. Import the component and prop types:

import type { DateTimePicker, DateTimePickerProps } from 'smart-webcomponents-react/datetimepicker';

The generated wrappers expose on* callbacks (for example onChange) whose arguments are standard DOM Event values unless the widget typings narrow them further.
