RequiredFieldValidator client side validations do not work on IE 10
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. 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. Has anyone here faced similar problem? Nag please check these link1 and link2 Edit: I got this fix from..
