Here is the code:
[Code]....
code behind:
[Code]....
The problem is that if the textcap changetext event is fired which is in the updatepannel then the captcha will always validate to false. If the textcap changetext event is not fired then all goes well.
I tried this link to generate verification Image [URL] ..... It works fine.
But I'd like to put a button in page for regenerating captcha for example. When the image was unreadable for user.
So I put an updatepanel in page and this is my code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<tr> <td colspan="2">
<asp:Image ID="imCaptcha" ImageUrl="~/Captcha.ashx" runat="server" />
[Code] .....
Although the image changes but the whole page is refreshed. Whether this is due to incompatibilities httphandler and updatepanel?
I have implemented captcha in my Register.aspx page. I am verifying captcha at server side. here is the code which is working fine.
protected void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
{
bool IsCaptcha;
IsCaptcha = validateCaptcha();
if (IsCaptcha == true)
StringBuilder bodyMsg = new StringBuilder();
TextBox textBoxUserName = (TextBox)CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("UserName");

View 10 RepliesI have a blank page with a Captcha called Captcha.aspx. I would like to add this as the second step to a CreateUserwizard. The following is what I want to achieve:i) User enters their Username etc in CreateUserwizard and clicks the CreateUser Button(ii) After clicking the CreateUser button, user sees the Captcha.aspx page and enters the correct stuff in the Captcha box and click a continue button(iii) User account is created if correct details were entered in the Captcha else no account is created, rather the user is sent to a page informing him or her that no account has been created
