I have a MasterPage in ASP.NET that creates consistent layout for the pages of my application but there are some pages that are put in separate file so it doesn't have a MasterPage.

I also have a separate file page WACHeader.ascx for header.

So what I want to do is put a common header or the common lay out to the pages that are placed in separate file.

How can I add the MasterPage in the separate file page without getting an error?

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="TestLogin.aspx.vb" Inherits="ECM.TestLogin" %>

Because every time I add


I get an error

Content controls have to be top-level controls in a content page or a nested master page that references a master page.

How can I put my common header?

What I have tried:

I tried this

<head runat="server">
    <link id="Link1" runat="server" rel="shortcut icon" href="favicon.ico" type="image/x-icon" />
    <title>ECM Test Login</title>
    <link rel="stylesheet" href="cssFramework/ecmStyle2.css" type="text/css" media="screen, projection" />
    <link href="WAC/WACHeader.ascx" type="text/asp" />

But the header doesn't show.

I thought of linking the WACHeader page to TestLogIn page but how?

Please help me with this. Thanks.

just add the UserControl soon after the body tag in the pages where master page reference is not added, it will act like common header
    <form id="form1" runat="server">
        <uc1:WACHeader runat="server" ID="WACHeader" />

uc means for user controls right? Do I need to put something for that? I got an error 'Unknown server tag 'uc1:WACHeader'.

It says 'Unrecognized tag prefix or device filter 'uc1', I'm sorry I'm not familiar with this. Can you explain it to me? Thanks

just drag and drop the file from the solution explorer, it will format the tag automatically.

since you have used ascx file, i assumed that you have used user control

Simple adding the MasterPageFile reference will not work, did you also move the content into a ContentPlaceHolder?

Here what I would suggest, open a file XYZ.aspx that is currently using the master page, then compare it with TestLogin page. Modify the TestLogin page structure to match XYZ.aspx. For instance, if you look at XYZ.aspx, do you see doctype, html, head, body... elements? Then which element the XYZ page contents wrap into?

I tried this already, I modified the TestLogin page to match the page that is currently using the master page. And I got an HTTP Error 404 - Not Found. when I run my application.

I don't think that error had anything to do what you did. That HTTP Error 404, sound like the page TestLogin.aspx not there.
