的FindControl属性的CreateUserWizard不工作 [英] Findcontrol property not working in createUserWizard

问题描述

我使用ASP的CreateUserWizard控件创建我的用户，我想添加一些额外的字段（用户额外的信息），我在我自己的表正在挽救。

我尝试访问code这些自定义的文本框后面的findContol财产（因为他们是里面的CreateUserWizard）

问题是，我声明并初始化作为控制，文本框为空。
以下是我如何做到这一点：

 文本框t_desc =（文本框）（CreateUserWizard1.FindControl（txt_desc））;
o.organisation_description = t_desc.Text;
 

这是控制是如何嵌套的：

 ＆LT; ASP：CreateUserWizard控件ID =CreateUserWizard1=服务器
      oncreateduser =CreateUserWizard1_CreatedUser＆GT;
   ＆LT; WizardSteps＆GT;
       ＆LT; ASP：CreateUserWizardStep ID =CreateUserWizardStep1=服务器
                    标题=Registreer UW organisatie＆GT;
         ＆LT;＆的ContentTemplate GT;
            ＆LT; D​​IV CLASS =行＆GT;
               ＆LT; D​​IV CLASS =半壁江山＆GT;
                  ＆LT;表＆gt;
                     ＆所述; TR＆GT;
                        ＆LT; TD ALIGN =右＆GT;
                           ＆LT; ASP：标签ID =lbl_organisation_description=服务器AssociatedControlID =txt_desc＆GT; Beschrijf UW organisatie：LT; / ASP：标签＆gt;
                        ＆LT; / TD＆GT;
                        ＆所述; TD＆GT;
                           ＆LT; ASP：文本框ID =txt_desc=服务器的ValidationGroup =CreateUserWizard1＆GT;＆LT; / ASP：文本框＆GT;
                        ＆LT; / TD＆GT;
                      ＆LT; / TR＆GT;
                    ＆LT; /表＆gt;
                  ＆LT; / DIV＆GT;
                ＆LT; / DIV＆GT;
              ＆LT; /＆的ContentTemplate GT;
              ＆LT; / ASP：CreateUserWizardStep＆GT;
          ＆LT; / WizardSteps＆GT;
＆LT; / ASP：＆的CreateUserWizard GT;
 

解决方案

  CreateUserWizardStep步=（CreateUserWizardStep）CreateUserWizard1.FindControl（CreateUserWizardStep1）;
 如果（步骤！= NULL）
 {
     TXT文本框=（文本框）step.ContentTemplateContainer.FindControl（txt_desc）;
 }
 

或者如果你可以看到从服务器 - code你的脚步控制

  TXT文本框=（文本框）CreateUserWizardStep1.ContentTemplateContainer.FindControl（txt_desc）;
 

I'm using ASP's createUserWizard control to create my users, and I'd like to add some extra fields (with extra info on the user) which I'm saving in my own table.

I try to access these custom textboxes in code behind with the findContol property (since they're inside the createUserWizard)

The problem is that the textbox I declare and initialize as the control, is null. Here's how I do it:

TextBox t_desc = (TextBox)(CreateUserWizard1.FindControl("txt_desc")); 
o.organisation_description = t_desc.Text;

And this is how the control is nested:

<asp:CreateUserWizard ID="CreateUserWizard1" runat="server"     
      oncreateduser="CreateUserWizard1_CreatedUser">
   <WizardSteps>
       <asp:CreateUserWizardStep ID="CreateUserWizardStep1" runat="server" 
                    Title="Registreer uw organisatie">
         <ContentTemplate>
            <div class="row">
               <div class="half">
                  <table>
                     <tr>
                        <td align="right">
                           <asp:Label ID="lbl_organisation_description" runat="server" AssociatedControlID="txt_desc">Beschrijf uw organisatie:</asp:Label>
                        </td>
                        <td>
                           <asp:TextBox ID="txt_desc" runat="server" ValidationGroup="CreateUserWizard1"></asp:TextBox>
                        </td>
                      </tr>
                    </table>
                  </div>
                </div>
              </ContentTemplate>
              </asp:CreateUserWizardStep>
          </WizardSteps>
</asp:CreateUserWizard>

解决方案

 CreateUserWizardStep step =   (CreateUserWizardStep)  CreateUserWizard1.FindControl("CreateUserWizardStep1"); 
 if (step!=null)
 {
     TextBox txt =  (TextBox)step.ContentTemplateContainer.FindControl("txt_desc");
 }

or if you can see your step control from server-code

TextBox txt =  (TextBox)CreateUserWizardStep1.ContentTemplateContainer.FindControl("txt_desc");
