Captcha Validation no working

[Bryan Hughes]

I have form that uses validation summary, textbox (with required validator and custom validator), captcha and submit button.  All validators, including captcha are using group.  EnableClientScript=False.  The custom validator does a sever side check to see if email is in system.

If the custom validator is false the Capthca validator also works, but if custom validator is true then captcha never validates.  I am assuming I need to fire server side validation for Captcha, but not sure how I should do it.

Here is page

Here is code behind

        mm.IsBodyHtml = True
        smtpClient.Timeout = 5000
        smtpClient.Send(mm)
        mm.Dispose()

        pan1.Visible = False
        pan2.Visible = True
        litins.Visible = False
    End Sub


End Class

How can I check if captcha is also valid?

Thank you,
Bryan

I figured it out

I just added
radcaptcha1.Validate()
Page.Validate("SubmitInfo")
If Not radcaptcha1.IsValid Then
    Exit Sub
End If

Works Great.
