    HI everyone,

    I need some help. I can show the CAPTCHA in the registration form 
    but I cannot  do the validation I wanted. I want to validate the CAPTCHA before finished the registration.

    <sitefinity:TextField runat="server" DisplayMode="Read" Value='<%# Eval("emailNotice")%>' /><%@ Control Language="C#" %>
    <%@ Register TagPrefix="sf" Namespace="Telerik.Sitefinity.Web.UI.Fields" Assembly="Telerik.Sitefinity" %>
    <%@ Register TagPrefix="sf" Namespace="Telerik.Sitefinity.Web.UI" Assembly="Telerik.Sitefinity" %>

    RadCaptcha is implemented in Forms module since 6.2. You could create a registration form using the form builder and add Captcha easily.

    The approach for adding Captcha to a registration widget is by making a custom widget replacing the original one. Please find the control attached. For your convenience I also have recorded a short video to demonstrate the whole process of implementation:


    As you can see from the video the widget does not need any configurations in order to work properly. In my case I have registered the widget directly in the ToolboxesConfig.config file, but you can register it from the backend.

    In case you want to implement Captcha for versions prior to 6.2 using form builder, please refer to this blogpost:
