Only Content Controls are Allowed (C# webcontrols)
So, I'm not sure what's going on. My boss wasn't pleased with me using MVC and Razor, so I'm being forced to code with this nasty webcontrol/codebehind style. =/
The error is:
Only Content controls are allowed directly in a content page that contains Content controls.
Here is the masterpage:
<%@ Master Language="C#"%>
<!DOCTYPE html>
<html>
<head>
<title>Application Form</title>
</head>
<body>
<div id="container">
<asp:contentplaceholder id="contentPlaceHolder" runat="server" />
</div>
</body>
</html>
And here is the Default.aspx page that's throwing the error.
<%@ Page Language="C#" Inherits="dumb.Default" MasterPageFile="MasterPage.master" %>
<h2>Application Form</h2>
<asp:Content id="content" ContentPlaceHolderID="contentPlaceHolder" runat="server">
<p>Please complete this application.</p>
<form action="Default.aspx" method="post" runat="server">
<div>
<span class="spaced">Name:</span><asp:TextBox id="name" runat="server" />
</div>
</form>
<p>
<asp:Label id="finalmessage" runat="server" />
</p>
</asp:Content>
And the silly Default.aspx.cs codebehind...
using System; using System.Web; using System.Web.UI;
namespace dumb
{
public partial class Default : System.Web.UI.Page
{
protected void Page_Load (object sender, EventArgs e)
{
if (IsPostBack) {
finalmessage.Text = "Submission Processed Successfully!";
}
}
}
}
Answer
All of your content, including static HTML must be inside Content tags in the content page. You have a <h2> outside:
<h2>Application Form</h2>
<asp:Content id="content" ContentPlaceHolderID="contentPlaceHolder" runat="server">
Should be:
<asp:Content id="content" ContentPlaceHolderID="contentPlaceHolder" runat="server">
<h2>Application Form</h2>
