Grid for React

React version of this topic (compatible with React 19+). Keep the same configuration logic from JavaScript and pass it as component props.

What this topic covers: practical setup, the framework-specific API access pattern, and copy-adapt guidance for the examples in this page.

import React, { useMemo, useRef } from 'react';
import { Grid } from 'smart-webcomponents-react/grid';
import 'smart-webcomponents-react/source/styles/smart.default.css';

export default function App() {
  const componentRef = useRef(null);
  const componentProps = useMemo(() => ({
    // Copy this topic's JavaScript configuration here.
  }), []);

  return <Grid ref={componentRef} {...componentProps}></Grid>;
}

Use componentRef.current for API methods in this topic.

Row Freeze

Rows can be frozen either to the 'top' or to the 'bottom'. The feature is also known as pinned rows and floating rows. To freeze a row, you need to set the row.freeze property.

Example: 
onRowInit(index, row) {
	if (index < 3) {
		row.freeze = true;
	}
}


To freeze a row to the bottom, set the row.freeze property to 'far'. 
onRowInit(index, row) {
	if (index > 2996) {
		row.freeze = 'far';
	}
}

Implementation Notes

Compatibility: React 19+   API access pattern: const componentRef = useRef(null) + componentRef.current.method()

Lifecycle guidance: Use useMemo for large config objects and call imperative API through componentRef.current after first render.

Common pitfalls:

  • Recreating columns/dataSource objects on every render can reset component state.
  • Calling API methods before ref is available causes runtime errors.
  • Mixing controlled and imperative updates without sync can lead to stale UI.

Validation checklist:

  • Keep config objects memoized when possible.
  • Guard API calls with ref existence checks.
  • Verify CSS theme import is present once per app.
