react-admin: Handle click event in Custom Field within a <Datagrid>

Question

In our react-admin application, first we display a products list.

On each row we also display a TextField (to allow user input number of copies) and a 'Print' button.

The snippet as below:

export const ProductList = props => (
  <List filters={<ProductFilter />} exporter={false} {...props} >
    <Datagrid rowClick="edit" >
      <TextField source="id" />
      <TextField source="productName" />
      <PrintPanel label="Print" />
    </Datagrid>
</List>
);

with custom field PrintPanel as below:

import TextField from '@material-ui/core/TextField';
import Button from '@material-ui/core/Button';

class PrintPanel extends React.Component {
  state = {
    copies: 1,
  }
  render() {
    return (
      <span>
        <TextField label="Number of copies"/>
        <Button variant="contained" color="primary"
          onClick={() => alert(1)}   // PROBLEM: this is NOT called when user click the button
        >
          Print
        </Button>
      </span>
    );
  }
}

The problem is: when user click the 'Print' button, react-admin open the 'Edit' page instead and Button's onclick is not called.

My question is: how to fix this?

Answer 1

Try this: onClick={ (e) => { e.stopPropagation(); alert(1) } }

If it does not help, update the react-admin version, this error has already been fixed.
