  asp.net WebForms Ajax Recaptcha .Validate() is always returning false

  Feb 04, 2013 08:40 PM|LINK

  I used this exact same technique before and it always worked.  For some reason when I'm doing this now the isvalide is always returning false.  Can anyone explain this?  Any help would be great.  Every variation I try still returns a fail.
  
  Thanks!
   

  <%@ Register TagPrefix="recaptcha" Namespace="Recaptcha" Assembly="Recaptcha" %>
  

  <recaptcha:RecaptchaControl ID="recaptcha"
                                                  runat="server"
                                                  Theme="clean"
