Hello Saroj,

Thanks for using Sitefinity.

The captcha form project is in the SDK under samples. You can download the SDK from here.

I hope this helps.

Hi

i have downloaded the SDK and installed but didn't get any Captcha project in the sample folder. Please send me the exact link to download or give me a zip file of the captcha project if you have.

Thanks in advanced

Dear Patrick

Still think Chaptcha support for forms build should come out of the box.

Saroj vote here: http://www.telerik.com/support/pits.aspx#/details/Issue=10655 already 43 votes. So Telerik this is a requeste feature!

Does anyone know where the captcha project went? It's no longer in the SDK.

Hello Mark,

The project is not removed from the Sitefinity SDK. Check the Akismet(http://akismet.com/) integration sample available there.

I'm embedding this into my randomsitecontrols on next release...but...

1) Add captcha to your forms toolbox, just edit your toolboxconfig and add this node (on the same level as the others)

<toolbox name="FormControls">

<sections>

<add name="Common">

<tools>

<add enabled="True" type="Telerik.Web.UI.RadCaptcha, Telerik.Web.UI" title="RadCaptcha" description="RadCaptcha" visibilityMode="None" name="RadCaptcha" />

</tools>

</add>

</sections>

</toolbox>

Now when you edit a form, the captcha will be available for drag\drop and you can edit and set properties on it (like skin\etc).

2) Drop this code into your site...it just inherits from the default form to look for a valid captcha before save...so just enhances the default control, it's not really that "custom"

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Linq;

using System.Net;

using System.Net.Mail;

using System.Text;

using System.Text.RegularExpressions;

using Telerik.Microsoft.Practices.EnterpriseLibrary.Logging;

using Telerik.Sitefinity.Configuration;

using Telerik.Sitefinity.Modules.Forms;

using Telerik.Sitefinity.Modules.Forms.Web.UI;

using Telerik.Sitefinity.Modules.Forms.Web.UI.Fields;

using Telerik.Sitefinity.Services;

using Telerik.Sitefinity.Web.UI;

using Telerik.Sitefinity.Web.UI.Fields;

using Telerik.Web.UI;

namespace RandomSiteControls.Forms

/// <summary>

/// Add the captcha control to your toolbox like this

/// <toolbox name="FormControls">

/// <sections>

/// <add name="Common">

/// <tools>

///                     <add enabled="True" type="Telerik.Web.UI.RadCaptcha, Telerik.Web.UI" title="RadCaptcha" description="RadCaptcha" visibilityMode="None" name="RadCaptcha" />

/// </tools>

/// </add>

/// </sections>

/// </toolbox>

/// </summary>

public class FormCaptcha : FormsControl

protected override void InitializeControls(GenericContainer container)

if (!SystemManager.IsDesignMode)

//Hide the form if JS is disabled, it'll let them bypass the required fields.

base.InitializeControls(container);

this.BeforeFormSave += new EventHandler<CancelEventArgs>(FormsControlCustom_BeforeFormSave);

#region EVENTS

protected void FormsControlCustom_BeforeFormSave(object sender, CancelEventArgs e)

if (this.MyCaptcha != null)

if (!this.MyCaptcha.IsValid)

e.Cancel = true;

this.MyCaptcha.ErrorMessage = this.CaptchaErrorMessage;

#endregion

#region METHODS

#endregion

#region Properties

private RadCaptcha _captcha = null;

protected RadCaptcha MyCaptcha

get

if (!SystemManager.IsDesignMode)

foreach (var control in this.FormControls.Controls[1].Controls)

if (control.GetType() == typeof(RadCaptcha))

_captcha = control as RadCaptcha;

break;

return _captcha;

private string _captchaErrorMessage = "Invalid Code, please try again";

/// <summary>

/// This gets edited in advanced mode

/// </summary>

public string CaptchaErrorMessage

get

return _captchaErrorMessage;

set

_captchaErrorMessage = value;

#endregion

3) Edit your toolboxes.config again, find the forms control, and set it's type to be the above type
<namespace>.<classname>, <assembly>
Ex: RandomSiteControls.Forms.FormCaptcha, SitefinityWebApp

Done...and works, just implimented this again on another site last night weirdly enough

The Sitefinity Hero strikes again! Thank you Steve

**JUST KEEP IN MIND**
If you have a form on an existing page, you'll need to delete the control, and then re-drag it from the toolbox. Reason being is the one on the page IS the "FormsControl" not my enhanced "FormCaptcha"
