Hello,

I added a rad captcha control, a button and  the "validationgroup" to each of the controls to a page that has nothing else.

On Page Load I added the following code:
        If RadCaptcha1.IsValid Then
            Response.Write("Valid")
        Else
            Response.Write("NOT VALID")
        End If

I get "Valid" when the page loads and there is no text in the captcha textbox.

what am I missing?

Please help - thank you.

Hi Tracy,

The isValid property of RadCaptcha is usually used in the server-side event handler of a control that postbacks and causes validation. In your case this is the button control and you can use its click event handler as shown in this online demo.

If you want to check if the RadChaptcha is validated on Page_Load, you should call its method Validate() before performing the check:
RadCaptcha1.Validate()
If RadCaptcha1.IsValid Then
    Response.Write("Valid")
Else
    Response.Write("NOT VALID")
End If
