How to access child component functions via refs

Redux connect accepts an option parametre as the forth parameter. In this option parameter you can set the flag withRef to true. Then you can access functions to refs by using getWrappedInstance(). Like this:

class MyDialog extends React.Component {
  save() {
    this.refs.content.getWrappedInstance().save();
  }

  render() {
    return (
      <Dialog action={this.save.bind(this)}>
        <Content ref="content"/>
      </Dialog>);
   }
}

class Content extends React.Component {
  save() { ... }
}

function mapStateToProps(state) { ... }

module.exports = connect(mapStateToProps, null, null, { withRef: true })(Content);
