Hello all:

I am using VS2005 pro, and, I have a single master page with some derived content pages. The content in the master page is not showing up in any of the derived content pages. Has anyone out there had this problem, and what was the fix?

Thanks
MeonR

Cannot find ContentPlaceHolder 'ContentPlaceHolder1' in the master page
Click to expand...
As the error says, your Content Page is looking for a ContentPlaceHolder named "ContentPlaceHolder1":
Code: 
<asp:Content ID="Content1" ContentPlaceHolderID="[!]ContentPlaceHolder1[/!]" Runat="Server">
but your master page only has a ContentPlaceHolder named "cp1":
Code: 
<asp:contentplaceholder id="[!]cp1[/!]" runat="server">

Thanks Mark,

That worked, manually changing the id of the contentplaceholder did it, odd, changes use to show up automatically.

Thanks

I spoke to soon. Now it won't let me add anything to the derived page. the content place holder on the derived page now just says master. and will not let any controls be added?

Thanks
MeonR

If you mean that you can't drag and drop any controls via the design window in the IDE then I'm not sure what the issue is, I always use the HTML view and write out any controls I need so that I have 100% control over what is rendered to the final page.

That's pretty much it. Its like the master and the derived page are locked together and I can edit the master but nothing else. the html view does not even appear when on the derived page. I am wondering if this is not a case of some @$%^*( update from MS screwing things up??

Thanks
MeonR

There's no update issue. I haven't heard of this problem before. If you can, I would just create another project from scratch and try again. There may be something corrupt in the project for soulution.

Thanks All

I created another project as you suggested, same problem, its like the master and derived pages are locked together and I can only edit the master page. I also went to another project I had and did the same thing, worked fine?!?! Any ideas?

Thanks
MeonR

Thanks... I also noted that the contentplaceholder on the derived page is in design view showing Content - Content1(Master) instead of custom as it usually does.

Here is the code

//Master
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="MasterPage" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "
<html xmlns=" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:contentplaceholder id="ContentPlaceHolder1" runat="server">
<asp:Menu ID="Menu1" runat="server" Height="51px" Orientation="Horizontal" Style="z-index: 100;
left: 279px; position: absolute; top: 0px" Width="455px">
</asp:Menu>
</asp:contentplaceholder>
</div>
</form>
</body>
</html>


//Content Page
<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "
<html xmlns=" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>

</div>
</form>
</body>
</html>

Thanks:

Ok, I manually added the asp:content control but its still not picking up the content from the master page. Something else is going on.
