在createuserwizard中查找Captcha控件 [英] Finding Captcha control inside createuserwizard

问题描述

我正在将Captcha控件集成到CreateUserWizard中.

因为我想使用if .. else ..语句根据验证码对用户的输入进行验证.但是，当我尝试从createuserwizard获取Captcha控件时发生错误.

这是错误:

The name ''Captcha1'' does not exist in the current context

我曾尝试将此控件作为文本框，图像，控件获取，但未成功.

这是代码:

 <   asp:CreateUserWizardStep     ID   ="   ID span>    runat   =" 服务器" <   ContentTemplate  > 

<   tr  > 
<   td     ="   style4" <  > 
<   td  > 


<   cc1:CaptchaControl     ID   ="   runat   服务器" 
  CaptchaBackgroundNoise   ="  
 
  CaptchaLength   ="  
 
  CaptchaHeight   ="  
 
  CaptchaWidth   ="  
 
  CaptchaLineNoise   ="  
 
  CaptchaMinTimeout   ="  
 
  CaptchaMaxTimeout   ="    
 
  FontColor     =" #FF33CC" 
  CaptchaFontWarping   ="    / > 

<   asp:TextBox    运行  ="   ID    txtCaptcha " / <  /td  > 
<  /tr  > 
<  /ContentTemplate  > 

<  /asp:CreateUserWizardStep  >  

这是后面的代码:

 受保护的 无效 CreateUserWizard1_CreatedUser(对象发​​件人，EventArgs e)
    {
        // 控件Captcha1 =(Control)CreateUserWizardStep1.ContentTemplateContainer.FindControl("Captcha1"); 
        TextBox txtCaptcha =(TextBox)CreateUserWizardStep1.ContentTemplateContainer.FindControl(" );

            Captcha1.ValidateCaptcha(txtCaptcha.Text.Trim()); // 此处发生错误

        如果(Captcha1.UserValidated)// 此处发生错误
        {

     }

}

I am integrating a Captcha control inside a CreateUserWizard.

As I wanted to do a validation for user''s input based on the Captcha using an if.. else.. statement. However an error occured when I trying to get the Captcha control from the createuserwizard.

Here the is error :

The name ''Captcha1'' does not exist in the current context

I had tried to get this control as a textbox, image, control but it was not successful.

Here is the code :

<asp:CreateUserWizardStep ID="CreateUserWizardStep1" runat="server">
<ContentTemplate>

<tr>
<td class="style4">Answer:</td>
<td>


<cc1:CaptchaControl ID="Captcha1" runat="server"

CaptchaBackgroundNoise="Medium"

CaptchaLength="5"

CaptchaHeight="55"

CaptchaWidth="200"

CaptchaLineNoise="None"

CaptchaMinTimeout="5"

CaptchaMaxTimeout="240" 

FontColor = "#FF33CC"

CaptchaFontWarping="Medium" />

<asp:TextBox runat="server" ID="txtCaptcha" />

</td>
</tr>
</ContentTemplate>

</asp:CreateUserWizardStep>

Here is the code at the behind :

protected void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
    {
        //Control Captcha1 = (Control)CreateUserWizardStep1.ContentTemplateContainer.FindControl("Captcha1");
        TextBox txtCaptcha = (TextBox)CreateUserWizardStep1.ContentTemplateContainer.FindControl("txtCaptcha");

            Captcha1.ValidateCaptcha(txtCaptcha.Text.Trim());//error occurred here

        if (Captcha1.UserValidated)//error occurred here
        {

     }

}
