How to focus a Textfield after clicking a button. I tried to use autoFocus but it did not work out: Example sandbox

Answer 1

First, onclick must be correct like onClick,
then if you want to use it inline your JSX code, it can help.
I tested it with react 16, it works.

  this.myTextField.focus()}>
    Click to focus Textfield
 

 (this.myTextField = el)} />
