title: RequiredFieldValidator client side validations do not work on IE 10
body: <p>All my webforms using RequiredFieldValidator, RegularExpressionValidator and ValidationSummary are not working on IE 10. It is working fine on any other browsers. It is strangely doing postback which does not happen on any other browsers.</p>
  
  <p>Another strange thing is when I open developer console(F12), it seems to be working but it is still doing postback. All these Validations should occur at client side by default.</p>
  
  <p>Has anyone here faced similar problem?</p>
