when i used telerik captcha in normal "aspx" page it works perfectly but when i used in user control "ascx" page its not validating

i used the captcha with asp:button control and validation group ="submitgroup" for both captcha and button

The Code in aspx page:

<

 

rad:RadAjaxPanel ID="rjPnlRegister" runat="server" LoadingPanelID="ajxldpnlRegister">

 

<

 

rad:RadCaptcha ID="rdCaptcha" runat="server" ErrorMessage="You have entered an invalid code." ValidationGroup="SubmitGroup">

 

 

 

 

 

</rad:RadCaptcha>

 

 

 

 

 

<asp:Label ID="lblStatus" runat="server" Text="Label"></asp:Label>

 

 

 

 

 

<asp:Button ID="btnSubmit" runat="server" Text="Button"

 

 

ValidationGroup="SubmitGroup" onclick="btnSubmit_Click" />

 

 

 

 

 

</rad:RadAjaxPanel>

 

<

 

rad:RadAjaxLoadingPanel ID="ajxldpnlRegister" runat="server" Transparency="20" BackColor="#FFFFFF">

 

 

 

 

 

<asp:Image runat="server" ID="imgLoading" SkinID="imageajaxloading" AlternateText="" />

 

</

 

rad:RadAjaxLoadingPanel>

The Code in aspx.cs page:

 

protected

 

void btnSubmit_Click(object sender, EventArgs e)

 

{

 

if (Page.IsValid)

 

{

lblStatus.Text =

"correct!";

 

lblStatus.ForeColor = System.Drawing.

Color.Red;

 

}

}

I tested same code in ascx page and aspx page but in aspx page it works fine in aspx page i.e its validating correctly
but in ascx page its not validating when click on the button

can any tell why its happening like that....

Hello Tony,

Are you by any chance loading the user control dynamically, because the control should be loaded at Page.Init in order for the RadCaptcha control to work correctly? Please, register the UserControl directly in the .aspx page, or load it at Page.Init, and if the problem persists, send us a fully working sample project that demonstrates the issue.

Sincerely yours,
Pero

I'm load ascx user control with captcha and it's never been validated, even if I enter right code which I can see on a textbox by captcha.CaptchaImage.Text.
Pero, you wrote " register the UserControl directly in the .aspx page, or load it at Page.Init"

How can I do it?

I'm doing 

        Contact contact;
        protected void Page_Load(object sender, EventArgs e)
        {
            contact = (Contact)Page.LoadControl("~/Contact.ascx");
        }

in .aspx file

then, on menu (in aspx) selection, I fill PlaceHolder with
contact by myPlaceHolder.Controls.Add(contact)

I set all elements in my ValidationGroup with SubmitGroup. SubmitButton and captcha as well.
All elements from the resulting page, such as RequiredFieldValidator (3 of them at the form) are working ok, but the captcha IsValid property is always false.

What am I doing wrong?

Hi Vitali,

In order for the RadCaptcha to work correctly in a UserControl scenario, the UserControl must be loaded in the Page_Init, if created dynamically, or registered directly on the Page. So, please change your source code to load the control in the Page_Init, and see if you still get the same behavior. You can also call RadCaptcha.Validate(), and Page.Validate() methods before, checking the IsValid properties, just to be sure that the Validation has occurred. Here is a sample code:

RadCaptcha1.Validate();
Page.Validate();
 
if(RadCaptcha1.IsValid)
{
///source code
}

We will do our best to improve the control in one of our future releases.
