I am currently referencing this website for AD role management.
The C# code is working fine, but when I pasted the code inside my webpage along with the masterpage, the page gave me an error which says:
Content controls have to be top-level controls in a content page or a nested master page that references a master page.
May I know how should I set my masterpage in this case?
.ASPX page without masterpage:
<%@ Page Language="C#" %>
<%@ Import Namespace="System.Web.Security" %>
<%@ Import Namespace="System.Web.UI" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
string[] rolesArray;
MembershipUserCollection users;
string[] usersInRole;
public void Page_Load()
{
....
}
public void AddUsers_OnClick(object sender, EventArgs args)
{
....
}
public void UsersInRoleGrid_RemoveFromRole(object sender, GridViewCommandEventArgs args)
{
....
}
</script>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
<title>Sample: Role Membership</title>

<body>
<form runat="server" id="PageForm">
<font face="helvetica" size="6" color="#455c75"><strong>Role Membership</strong></font><font face="helvetica" size="5" color="#455c75"><strong> Management</strong></font>
<br /><asp:Label ID="Msg" ForeColor="maroon" runat="server" /><br />
<table cellpadding="3" border="0">

</table>
</form>
Masterpage:
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="MainPage.master.cs" Inherits="MainPage" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">
<title>SOD</title>
<link href="Styles.css" rel="stylesheet" type="text/css" />
</head>
<body>
...
</body>
</html>
EDIT:
I tried inserting MasterPageFile="~/MainPage.master" into the first tag, which start my .aspx page with <%@ Page Language="C#" MasterPageFile="~/MainPage.master"%>, giving me the error mentioned above.
The Masterpage contains HTML code and content areas. The pages that use the masterpage must, MUST, have all code in an <asp:Content> tag. You can’t have any sort of code outside of the Content tag.
