必须使用runat = server放置在表单标记内

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...

我整个上午一直在尝试这个，没有结果。我似乎无法弄清楚我做错了什么。我已经检查了两个链接（在许多其他无用的链接中）并且尚未解决我的问题。这是一个WebUserControl ......

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

收到以下错误：控件'TextBox'类型的'HeadContent_CareersViewPosting_txtFirstName'必须放在带有runat = server的表单标记内。

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

已经尝试过这里的建议，这里和这里没有结果。仍然收到完全相同的消息。一些新的建议将不胜感激！

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

用户控件当前被放置在虚拟网页上以进行测试。这是'虚拟'页面代码。

<%@ 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>

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

在ASPNet webforms中 - 一切都需要在表单标记中运行。

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:

所有服务器控件必须出现在

标记内，标记必须包含runat =“server”属性。 runat =“server”属性表示应在服务器上处理表单。它还表明服务器脚本可以访问所附的控件：

<form runat="server">

...HTML + server controls

</form>

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

在您的虚拟页面中，尝试以下操作以允许服务器控件运行。

<%@ 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.

另外 - 检查你的〜/ Site.Master文件是否包含

如果不是 - 那么将它作为拥有所有封闭表单标记的地方是相当典型的。

所有服务器控件必须出现在

标记内，标记必须包含runat =“server”属性。

All the Asp.net controls are server controls,so these should be placed within form tag with runat="server" attribute, like this

所有Asp.net控件都是服务器控件，因此这些控件应放在带有runat =“server”属性的form标签中，如下所示

<form runat="server">

place server controls here...

</form>

 <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
