View 11 RepliesI have a working registration page and I'm adding CAPTCHA. The CAPTCHA works and I have a simple if/else loop to do what happens if the CAPTCHA input was correct or incorrect.
if (Page.IsValid)
{
feedback.InnerHtml = "Correct.";
//I would like to put something here to process the registration -- CAPTCHA was done correctly
}
else
{
feedback.InnerHtml = "Incorrect.";
}
I want to write something in the if/else loop that will enact the registration.
Therefore, my button in CustomNavigationTemplate,
<CustomNavigationTemplate>
<asp:Button ID="StepNextButton" runat="server" CommandName="MoveNext"
Text="Create User" ValidationGroup="CreateUserWizard1" />
</CustomNavigationTemplate>
is obsolete.
Is there something I can type that will programmatically achieve what this button performed?
I am using Jeff Atwood's captcha control in a CreateUserWizard. It all works, but I have an issue with the tabindex. I want the user to enter the captcha code, hit enter and that automatically fires the Next button on the wizard. No matter what combination of tabindexes I try, I can't get it to work.
