React getting access to properties of list component on click

it helps some times You aren't passing the id to the Seat component. So it makes sense why this.props.id is not there.
Either pass the id to the component:
code :
this.setState({seatId: this.props.value})

React: how to access component function from a click event on vis.js edge?

this one helps. You can change the function given to selectEdge to an arrow function to use the enclosing lexical scope instead, which has _openDialog on this.
code :
export default class App extends Component {
  // ...

  render() {
    return (
        <div className="tree_graph_div">
              selectEdge: (event) => {
                var { nodes, edges } = event;
                if (edges.length == 1) {
          <Dialog />

How to access properties of objects from a third-party DOM library used in a React component from the outside

I hope this helps you . Actually the flow should be the other way round, define the nodes outside of the component, then pass them in. For that define the constructor as:
code :
 constructor(props) {
    this.nodes = props.nodes;
 const nodes = new DataSet([/*...*/]);
 ReactDOM.render(<VisNetwork nodes={nodes} />,document.getElementById('mynetwork'));

Detect click outside a component react way NOT dom access

this one helps. If you really, really don't want to attach dom events to your components, you can add a 'dismisser' component behind the Crop component and handle the reset there.
code :
const Dismisser = ({ onClick }) => <div onClick={onClick} style={{
  position: 'fixed',
  top: 0, left: 0, right: 0, bottom: 0,
  zIndex: 100,
}} />
{src && (
  <div style={{position: 'relative', zIndex: 200}}>
  <Dismisser onClick={this.resetCrop} />

How to access method of another component on button click in React?

By : user3394988

it helps some times Generally, you're going to want to "lift" state up to a common ancestor. I took your code below and lifted state to a common "App" ancestor.
code :
class IncreaseDiceButton extends React.Component {
  render () {
    return (
      <button onClick={props.incrementState}>
        Increase Number Of Dice
class NumDice extends React.Component { 
  render() {
    return (
class App extends React.Component {
  constructor () {
    this.state = { mystate: 1 }; 

  incrementState = () => {
    var myNewState = this.state.mystate +1;
    this.setState({mystate: myNewState});

  decrementState = () => {
    var myNewState = this.state.mystate -1;
    if(myNewState > 0){
      this.setState({mystate: myNewState});

  render() {
    return (
      <NumDice mystate={this.state.mystate} />
      <IncreaseDiceButton incrementState={incrementState} />
