Warning: Unknown event handler property `onHeaderClick`. It will be ignored

Question

I am creating Higher order components for passing some props with another component. But getting the warning for Unknown event handler property.

 export class TableHeaderRow extends React.PureComponent{
     render() {
            const customCell = WrappedCellComponent(Cell,this.props.onHeaderClick, this.props.isMasterChecked, this.props.onTableCheckBoxselection);
            return (
                  <TableHeaderRowBase
                        cellComponent={customCell}
                        rowComponent={Row}
                        contentComponent={Content}
                        titleComponent={Title}
                        showSortingControls={true}
                        sortLabelComponent={this.props.sortLabelComponent}
                        groupButtonComponent={(data: any) : any => null}
                        showGroupingControls={false}
                        {...this.props}
                    />
            )
        }
    }

const WrappedCellComponent = (WrappedComponent, onHeaderClick,checkIfMasterChecked, onTableCheckBoxSelection) => {

    class HOC extends React.Component {
        render() {
            return <WrappedComponent 
                    {...this.props}  
                    onHeaderClick={onHeaderClick} 
                    onTableCheckBoxSelection={onTableCheckBoxSelection}  
                    checkIfMasterChecked={checkIfMasterChecked} 
                   />;

        }
    }
    return HOC;
};

Events are working, but I am getting error in chrome devTool (i.e. Warning: Unknown event handler property onTableCheckBoxSelection. It will be ignored.)

Answer 1

This basically happens when you pass a prop with a name starting with on, regardless of its case. React assumes and tries to bind it with javascript events like onClick, onKeypress, etc

Answer 2

The error is well documented:

The unknown-prop warning will fire if you attempt to render a DOM element with a prop that is not recognized by React as a legal DOM attribute/property. You should ensure that your DOM elements do not have spurious props floating around.
