How to handle "outside" click on Dialog (Modal) with material-ui

Question

My box closes when clicking outside of the box making me lose all the input. I want my box to close only when clicking on the cancel button. I am not sure what is making it close when clicking outside. Any help?

I am using @material-ui/core

  _close() {         DeviceCreationActions.close();     }  render() {         const actions = [             <Button                 id="device-create-dialog-close"                 key="device-create-dialog-close"                 onClick={this._close}             >               {this.context.intl.formatMessage({id: 'Cancel'})}             </Button>         ];          if (0 < this.state.stepIndex) {             actions.push(<Button                 id="device-create-dialog-back"                 key="device-create-dialog-back"                 onClick={this._previousStep.bind(this)}               >                 {this.context.intl.formatMessage({id: 'Back'})}               </Button>             );         }          if (             (1 >= this.state.stepIndex && 0 < this.state['formStep' + this.state.stepIndex].length) ||             (0 < this.state.stepIndex)         ) {             actions.push(<Button                 id="device-create-dialog-next"                 key="device-create-dialog-next"                 onClick={2 === this.state.stepIndex ? this._save.bind(this) : this._nextStep.bind(this)}               >                 {this.context.intl.formatMessage({id: 2 === this.state.stepIndex ? 'Create' : 'Next'})}               </Button>             );         } 

Answer 1

I think what you need is disableBackdropClick passed down to <Modal /> component

<Modal disableBackdropClick /> 

You can also disable close Dialog on Esc key press with disableEscapeKeyDown prop

Answer 2

disableBackdropClick will not work in Material UI v5.

Dialog API (next)

You can use code from the migration guide to handle each closing source manually with the onClose prop by detecting the source of the closing event.

<Dialog onClose={handleClose} /> 

And use the handler to stop it

const handleClose = (event, reason) => {     if (reason && reason == "backdropClick")          return;     myCloseModal(); }
