Hello,

I am using capcha with asp.net register controler so not able to check catcha validation from code behind.

Please suggest me how we can validate captcha from client side.

Validating on the client is pointless as your script can be updated by Malicious Malory or just removed altogether. There is probably a way of hooking into the events of the register control to ensure the captcha is valid, you're better off looking into that.
