Hi,

I am currently wanted to include my master page into a page that do not include master page initially. I'd tried this code,

protected override void OnPreInit(EventArgs e)
{
this.MasterPageFile = "~/Main.master";

base.OnPreInit(e);
}

but run into this error

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

What I am trying to do is to include a master page into the web page during run time as I only wanted the master page to be included when certain criteria is met.

I'd look around the net but still don't get it what went wrong, hope I can get some idea from here.

Thanks.

Can you post here .aspx code ?

Please make sure, do not put any controls out side the Content place holder and set property runat server.

Looks like you have some text or control placed outside asp:content tag. When you use master pages, make sure your controls and all other texts in the content page are inside the asp:content tag.

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

Ya, I read this about asp:content tag, but what I don't understand is I could not find asp:content tag in any of my page. Sorry this might sound silly, where should this asp:content tag suppose to be in? .master or .aspx?

It should be in a content page, not in master page.

I got your problem, you are trying to change a master page dynamically in a page where master page is not at all used. Try putting your ASPX page contents into

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
</asp:Content>

. Master page should contain body, form and a content placeholder. In your content page, supply the content placeholder id to asp:content's ContentPlaceHolderID property.

Hope this helps

I think it wont help, if master page is not referenced when he wants it not to contain one, then it will throw error again, coz of using content control without a master page.

I dont have a solution now, gotta check that out, if i get ill let ya know..

I think I slowly get what you mean. The content page is where all my textboxes, buttons are.

This is what I did, in my aspx page's html:

<asp:content id="Content1" contentplaceholderid="ContentPlaceHolder1" runat="Server">
<body>
</body>
</asp:content>

But I got the error when change it back to design view
Content control can only be use in a content page

I guess I still missing some point you trying to tell me?

sidbaruah9-Jun-08 0:23

9-Jun-08 0:23

Let me throw some light here...

If you are using a master page, the contents you are using for a page must be inside the content template as you mentioned in the post..

However, you could only have a master page on a page or you dont have one.. and as you cant change the aspx design page at runtime, it is bound to throw an error...

I suggest you use two different pages, one with master page and another without it, so that you could use them according to the situations you have..

Hi all,

I am generating some Excel files on the server as part of some reports generation process (I'm using the Apache POI library with IKVM). I am interested in printing them at once without involving the client-side and without having MS Excel installed on the server machine.
Is there any way to do this under the given conditions?
I would be interested even in some .NET library capable of doing this...

Thanks in advance!

Easy way is to keep the domain name in some configuration file. Read from that configuration file while you send email. When you upload website to server, change this value to a valid one.
