you would need to pass down each prop individually for each function that you needed to call
<createprofile
onfirstnamechange={this.firstnamechange}
onhide={close}
show={this.state.showmodal}
/>
and then in the createprofile component you can either do
const createprofile = ({onfirstnamechange, onhide, show }) => {...}
with destructuring it will assign the matching property names/values to the passed in variables. the names just have to match with the properties
or just do
const createprofile = (props) => {...}
and in each place call props.onhide
or whatever prop you are trying to access.

a variation of finalfreq's answer
you can pass some props individually and all parent props if you really want (not recommended, but sometimes convenient)
<createprofile
{...this.props}
show={this.state.showmodal}
/>
and then in the createprofile component you can just do
const createprofile = (props) => {
and destruct props individually
const {onfirstnamechange, onhide, show }=props;

just do this on source component
<mydocument selectedquestiondata = {this.state.selectedquestionanswer} />
then do this on destination component
const mydocument = (props) => (
console.log(props.selectedquestiondata)
);

an addition to the above answer.
if react
complains about any of your passed props
being undefined
, then you will need to destructure those props with default
values (common if passing functions, arrays or object literals) e.g.
const createprofile = ({
// defined as a default function
onfirstnamechange = f => f,
onhide,
// set default as `false` since it's the passed value
show = false
}) => {...}

i'm using react function component
in parent component first pass the props like below shown
import react, { usestate } from 'react';
import './app.css';
import todo from './components/todo'
function app() {
const [todos, settodos] = usestate([
{
id: 1,
title: 'this is first list'
},
{
id: 2,
title: 'this is second list'
},
{
id: 3,
title: 'this is third list'
},
]);
return (
<div classname="app">
<h1></h1>
<todo todos={todos}/> //this is how i'm passing props in parent component
</div>
);
}
export default app;
then use the props in child component like below shown
function todo(props) {
return (
<div>
{props.todos.map(todo => { // using props in child component and looping
return (
<h1>{todo.title}</h1>
)
})}
</div>
);
}
