必须放置在表单标签内使用runat = server [英] Must be Placed Inside a Form Tag With runat=server

问题描述

我一直在尝试这一切，没有结果。我似乎无法弄清楚我做错了什么。我检查了两个链接（在许多其他无用的链接之间）并且尚未解决我的问题。这是一个WebUserControl ...

接收到以下错误：
'TextBox'类型的控件'HeadContent_CareersViewPosting_txtFirstName'必须放置在窗体标签中，并且runat =服务器。

已经尝试了建议这里，这里和这里并且没有结果。仍收到完全相同的信息。

用户控件目前正放置在虚拟网页上进行测试。这是'虚拟'页面代码。

 <％@ Page Title =Language =C＃MasterPageFile = 〜/ Site.MasterAutoEventWireup =trueCodeBehind =页面职业查看Posting.aspx.csInherits =ascxStagingApplication.Careers.Page_Careers_View_Posting％> 
 
 <％@ Register Src =〜/ Careers / Careers查看Posting.ascxTagPrefix =uc1TagName =CareersViewPosting％> 
 
< asp：Content ID =Content1ContentPlaceHolderID =HeadContentrunat =server> 
< uc1：CareersViewPosting runat =serverid =CareersViewPosting/> 
< / asp：Content> 
  

解决方案

在ASPNet webforms中，所有内容都需要在表单中运行所有服务器控件都必须出现在< form> 标签中，< form> 标签必须包含 runat =server属性。 runat =server属性表示应该在服务器上处理表单。它还表明封闭的控件可以被服务器脚本访问：

 < form runat =server> 
 
 ... HTML +服务器控件
 
< / form> 
  

在您的虚拟页面中，请尝试以下操作以允许服务器控件运行。

 <％@ Page Title =Language =C＃MasterPageFile =〜/ Site.MasterAutoEventWireup =trueCodeBehind =Page Careers查看Posting.aspx.csInherits =ascxStagingApplication.Careers.Page_Careers_View_Posting％> 
 
 <％@ Register Src =〜/ Careers / Careers查看Posting.ascxTagPrefix =uc1TagName =CareersViewPosting％> 
< form runat =server> 
< asp：Content ID =Content1ContentPlaceHolderID =HeadContentrunat =server> 
< uc1：CareersViewPosting runat =serverid =CareersViewPosting/> 
< / asp：Content> 
< / form> 
  

另外 - 检查您的〜/ Site.Master文件是否包含< form runat =server> 如果不是这样的话，那么这将是您拥有所有封闭表单标记的地方。

I have been attempting this all morning with no results. I can't seem to figure out what I'm doing wrong. I have checked out the two links (among many other unhelpful links) and have yet to solve my issue. This is a WebUserControl...

Receiving the following error: Control 'HeadContent_CareersViewPosting_txtFirstName' of type 'TextBox' must be placed inside a form tag with runat=server.

Already attempted the suggestions here, here and here and no results. Still received the exact same message. Some new suggestions would be greatly appreciated!

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Careers View Posting.ascx.cs" Inherits="ascxStagingApplication.Careers.Careers_View_Posting" %>

            <td>
                <asp:Label ID="lblFirstName" runat="server" Text="* First Name"></asp:Label>

The user control is currently being placed onto a dummy webpage for testing. Here is the 'dummy' page code.

<%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Page Careers View Posting.aspx.cs" Inherits="ascxStagingApplication.Careers.Page_Careers_View_Posting" %>

<%@ Register Src="~/Careers/Careers View Posting.ascx" TagPrefix="uc1" TagName="CareersViewPosting" %>

<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">
    <uc1:CareersViewPosting runat="server" id="CareersViewPosting" />
</asp:Content>

解决方案

In ASPNet webforms - everything needs to run within a form tag.

All server controls must appear within a <form> tag, and the <form> tag must contain the runat="server" attribute. The runat="server" attribute indicates that the form should be processed on the server. It also indicates that the enclosed controls can be accessed by server scripts:

<form runat="server">

...HTML + server controls

</form>

In your dummy page try the following to allow the server controls to run.

<%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Page Careers View Posting.aspx.cs" Inherits="ascxStagingApplication.Careers.Page_Careers_View_Posting" %>

<%@ Register Src="~/Careers/Careers View Posting.ascx" TagPrefix="uc1" TagName="CareersViewPosting" %>
<form runat="server">
<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">
    <uc1:CareersViewPosting runat="server" id="CareersViewPosting" />
</asp:Content>
</form>

Also - check that your ~/Site.Master file contains the <form runat="server"> if not -a s it would be fairly typical for that to be the place to have your all enclosing form tag.
