the options are:

  1. clone and modify the recaptcha so you can execute your custom logic in the captcha's various events (such as the IsValid method). this is probably the one you want to use if you are trying to determine if it's valid or not.
  2. clone and overwrite the bizform web part so you can attach you custom logic and try to get the form value before submit.
  3. add a global event hook to the biz form in submit so you can retrieve the form info before submission and cancel the event if invalid.

out of curiosity what version of recaptcha are you trying to get to work? The human checkbox thing or the normal enter the random letters/numbers

The validation is already done with Google as to whether or not the data entered on the recaptcha is correct or not, so why do you need to re-verify it? Are you wanting to add additional verification in your form after submit?

I also need to modify the submit button for Kentico forms. However cloning the biz-form web part and looking in the code behind doesn't show the submit method. Where is the submit method located?

It would be the viewBiz.OnAfterSave event hook (if you're on kentico 10).

Hi Brenden/Trevor,

Thanks for your reply. I want to validate if captcha response is valid before submitting form data.

Is there any way to do this. I am using Googles new "I am not robot" captcha

The "I'm not a robot" captcha (checkbox) will validate once the box is checked. So it will be validated prior to the form being submitted. Secondly, if the form is submitted and the captcha has been invalidated or is invalid, the form submission will fail. So no need to perform any further validation as this is already done for you.

Have you looked at the New Recaptcha project code at all? I say download the code and read the documentation and make modifications as you see fit in the project code.

Thanks for your respond. I want to validate if captcha response is valid earlier than submitting shape statistics. So get in touch with our UK Essay Writing Service to get work that is calibrated to perfectly fulfil your needs.
