Seeing the tag "master-pages" included in the question, this error may pop up when you are trying to dynamically add text boxes (or for that matter, any control) in a content page which uses a master page. 看到问题中包含的标记“master-pages”，当您尝试在使用母版页的内容页面中动态添加文本框（或者就此而言，任何控件）时，可能会弹出此错误。
Only the master page contains a form with runat="server" set. 只有母版页包含设置了runat =“server”的表单。 The content pages only have content place holders. 内容页面只有内容占有者。
To dynamically add controls to a content page, include a panel in your desired contentplaceholder in your content page and then add controls to it in your code. 要动态地将控件添加到内容页面，请在内容页面中的所需contentplaceholder中包含一个面板，然后在代码中向其添加控件。 For example, 例如，
In your aspx file for the content page, add a panel like 在内容页面的aspx文件中，添加一个面板
<asp:Panel ID="Panel1" runat="server">
</asp:Panel>
Then, in your code behind, 然后，在你的代码背后，
Dim txtbox As New textbox()
Panel1.Controls.Add(txtbox)

Error happens because you placed your control with runat="server" outside the form tag (with runat="server" too). 发生错误是因为您将控件与runat =“server”放在表单标记之外（runat =“server”也是如此）。 ASP.NET requires to have all server controls inside one form with runat="server" attribute. ASP.NET要求使用runat =“server”属性在一个表单中包含所有服务器控件。

I ran into this too. 我也碰到了这个。 What I did, was just added a PageWrapper , and all the site's code went inside that. 我做了什么，只是添加了一个PageWrapper，所有网站的代码都在里面。 For example: 例如：
<body>
<div ID="PageWrapper">
<form ID="form1" runat="server">
<div ID="Header">...</div>
<div ID="MainContent">...</div>
...
</form>
</div>
</body>
Something like that. 这样的事情。 Hope this helps. 希望这可以帮助。

With standard ASP.Net, you can only have one form. 使用标准ASP.Net，您只能拥有一个表单。 Thats a limitation of ASP.Net. 这是ASP.Net的限制。 If youre going to be doing stuff that requires 2 or more <FORM> tags, you'll need MVC or something along the lines of. 如果您要做的事情需要2个或更多<FORM>标签，那么您将需要MVC或类似的东西。

You did not say where this control is on your form. 您没有说明此控件在您的表单上的位置。
If this error is a result of another control being inside a GridView control like I had, then this may help you, too: 如果这个错误是由于我有一个GridView控件内的另一个控件的结果，那么这也可以帮助你：
Control xxx of type 'LinkButton' must be placed inside a form tag with runat=server 必须将带有'LinkButton'类型的控件xxx放在带有runat = server的表单标签内

Error is Control 'txtTo' of type 'TextBox' which must be placed inside a form tag with runat=server. 错误是'TextBox'类型的控件'txtTo'，它必须放在带有runat = server的表单标签内。
ERROR is This Code. 错误是本规范。
<tr>
<td class="style1">
<strong>To </strong>
</td>
<td class="style2">
<strong>: </strong>
</td>
<td class="style6">
<asp:TextBox ID="txtTo" runat="server" Width="475px"></asp:TextBox>
</td>
<td></td>
</tr>

控件和表单标签都必须有runat="server"
