    Is there a way to avoid causing a new captcha image to be generated on a postback? For example, if i had a form with two dropdown lists that are dependent on each other, when the first dropdownlist fires an event to bind the second list, the captcha image regenerates.

    Hi Sam,

    The CaptchaImage is refreshed on every postback, and this is so by design (security reasons). There is no way to stop the RadCaptcha control, from recreating the CaptchaImage on every postback.

    Kind regards,
