    Hello Geetha,

    This behavior is expected, since RadCaptcha is designed to refresh its image on every postback. One approach is to use UpdatePanel with UpdateMode="Always".

    You can get more on this from the following forum which discussed the same.
    Captcha is not validating properly when post back

    Thanks,
    Shinu.

    Hi Geetha,

    You might also wanna try calling RadCaptcha.Validate(), and Page.Validate(validationGroup) before checking the IsValid property.

    It would sure be nice if this info about calling RadCaptcha.Validate and Page.Validate were actually in the RadCaptcha documentation.
    It seems to  me to be critical to the control working properly (at least it certainly was in my case) yet I had to spend time (a lot of time) spinning my wheels, searching forums, etc... to find a very simple solution but an undocumented one.
    Or rather, buried down in the Forums and Methods page but not mentioned in the First Look, Help, etc...

    Hi Paul,

    Truly, there are cases that require the use of the Validate method and that are not covered by the RadCaptcha documentation. Thank you for bringing this to our attention, the method and the scenarios, in which it should be utilized will be added with the next update of the RadCaptcha documentation.

    Kind regards,
