I've fixed the code from my previous post so reCAPTCHA is working properly now. There was no change to what I already posted about the Register.ascx.cs file, the only changes are in the Register.ascx file...

Here is my full Register.ascx file (changes from default are in bold):

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="Register.ascx.cs" Inherits="DotNetNuke.Modules.Admin.Users.Register" %>

<%@ Register TagPrefix="dnn" Assembly="DotNetNuke.Web" Namespace="DotNetNuke.Web.UI.WebControls" %>

<%@ Register TagPrefix="dnn" TagName="Label" Src="~/controls/LabelControl.ascx" %>

<%@ Register TagPrefix="dnn" Assembly="DotNetNuke" Namespace="DotNetNuke.UI.WebControls"%>

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

<div class="dnnForm dnnRegistrationForm">

    <div class="dnnFormItem">

        <div class="dnnFormMessage dnnFormInfo"><asp:label id="userHelpLabel" runat="server" /></div>

    </div>

    <br/>

    <div class="dnnFormItem dnnFormHelp dnnClear"><p class="dnnFormRequired"><span><%=LocalizeString("RequiredFields")%></span></p></div>

    <div class="dnnFormItem dnnClear">

        <dnn:DnnFormEditor id="userForm" runat="Server" FormMode="Short" />

        <div class="dnnSocialRegistration">

            <div id="mainContainer">

                <ul class="buttonList">

                    <asp:PlaceHolder ID="socialLoginControls" runat="server"/>

                </ul>

            </div>

        </div>

        <div style="clear:both;">

  <recaptcha:RecaptchaControl ID="recaptcha" runat="server" PublicKey="[PUBLIC KEY]" PrivateKey="[PRIVATE KEY]" />

  <img src="/spacer.gif" onload="reload_captcha();" />

        </div>

    </div>

    <div id="reCaptcha_widget" style="display:none;"></div>

    <div id="captchaRow" runat="server" visible="false" class="dnnFormItem dnnCaptcha">

        <dnn:label id="captchaLabel" controlname="ctlCaptcha" runat="server" />

        <dnn:captchacontrol id="ctlCaptcha" captchawidth="130" captchaheight="40" ErrorStyle-CssClass="dnnFormMessage dnnFormError dnnCaptcha" runat="server" />

    </div>      

    <ul id="actionsRow" runat="server" class="dnnActions dnnClear">

        <li><asp:LinkButton id="registerButton" runat="server" CssClass="dnnPrimaryAction" resourcekey="cmdRegister" /></li>

        <li><asp:LinkButton id="cancelButton" runat="server" CssClass="dnnSecondaryAction" resourcekey="cmdCancel" CausesValidation="false" /></li>

    </ul>

</div>

<script type="text/javascript" src="http://www.google.com/recaptcha/api/js/recaptcha_ajax.js"></script>

<script type="text/javascript">

function reload_captcha(){

 if($(".dnnFormValidationSummary").length > 0){

  Recaptcha.create("[PUBLIC KEY]", "reCaptcha_widget",

  {

   theme:"red",

   callback: Recaptcha.focus_response_field

  });

 }

}

</script>

(obviously change [PUBLIC KEY] and [PRIVATE KEY] to the actual public and private keys from google)

This is on DNN 6.2.5, btw

Bjirka,

I implemented your solution.  Thank you for the posting.  I was not able to use the free module from David Fenley at Interactive Web Solutions as we have not yet upgraded from ASPNet 2.0.

However, now I get BOTH the ReCatcha and the DNN Capcha controls on the Registration page.   This works fine provided that the new registrant enters both Re-Captcha and Captcha phrases.  This can be a little bit daunting.

Am I doing something wrong?
