I am trying to create a Main.master page with two ContentPlaceHolder sections.
When I load the default page, it only renders ContentPlaceHolder1, I have to actually load Second.aspx to see the second ContentPlaceHolder. Why?
In my Main.master I have:
<%# Master Language="C#" AutoEventWireup="true" CodeFile="Main.master.cs" Inherits="Main" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<asp:ContentPlaceHolder id="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<div>
<asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server"></asp:ContentPlaceHolder>
<asp:ContentPlaceHolder id="ContentPlaceHolder2" runat="server"></asp:ContentPlaceHolder>
</div>
</body>
</html>
Additionally, I have created two additional pages Default.aspx and Second.aspx:
Detault:
<%# Page Title="" Language="C#" MasterPageFile="~/Main.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
HOW HOW HOW HOW
</asp:Content>
Other page is
Second:
<%# Page Title="" Language="C#" MasterPageFile="~/Main.master" AutoEventWireup="true" CodeFile="Second.aspx.cs" Inherits="_Default" %>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder2" Runat="Server">
COW COW COW COW
</asp:Content>
Its only rendering the first PlaceHolder, how can I have separate content files and have the both rendered on the same page?
You have to ask yourself: If you navigate to Default.aspx, how will your application know to grab the content in Second.aspx? Simply put: it won't.
First, here's the MSDN on the ContentPlaceHolder.
You can have as many ContentPlaceHolders on your masterpage as you want, and EACH page can either render into these content areas or NOT.
So your Default.aspx can look like:
<%# Page Title="" Language="C#" MasterPageFile="~/Main.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
HOW HOW HOW HOW
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder2" Runat="Server">
COW COW COW COW
</asp:Content>
And you will get the results you are looking for.
Now, there are ways you can render an OUTSIDE html file INTO one of these content placeholders (one way would be javascript) - but (and please, someone correct me if I'm wrong) there won't be a way to do it with an ASPX webpage, codebehind or not.
To touch on your question:
how can I have separate content files and have the both rendered on the same page?

I have a project with a master page at the root level and multiple content pages which are at the root level as well. Everything has been looking fine until I created a new folder and put a new content page in that folder. None of the images are displaying for that particular page. I'm sure its something simple that I'm missing.
<%# Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="SupertonesInstallation.aspx.cs" Inherits="Articles_SupertonesInstallation" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="Home" Runat="Server">
content
</asp:Content>
So I've never really coded a website using ASP.NET. I'm trying to add a search form to a masterpage for my site. The problem is the whole body is wrapped in a form tag, which makes the functionality of my new form non-existant. I have a habbit of making bad situations worse by messing around with things I don't yet understand. So I thought I'd ask for your advice, my thoughts were:
Remove the runat="server" form tag completely.
Close it before my form and replace it at the end of my form.
Code within the button (which I later noticed you can't open.
Give up on ASP.NET and go back to PHP lol.
Hope you can help.
Thanks.
Master page will be like this
<%# Master Language="C#" AutoEventWireup="true"
CodeFile="MasterPage.master.cs" Inherits="MasterPage" %>
<!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 runat="server">
<title></title>
<asp:ContentPlaceHolder id="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ContentPlaceHolder id="bodycontent" runat="server">
</asp:ContentPlaceHolder>
</div>
</form>
</body>
</html>
you can write the search page like this
<%# Page Title="" Language="C#" MasterPageFile="~/MasterPage.master"
AutoEventWireup="true" CodeFile="Search.aspx.cs" Inherits="Search" %>
<asp:Content ID="Content1" ContentPlaceHolderID="bodycontent" Runat="Server">
//dnt include form tag here having runat = server
</asp:Content>
don't add content to the master page (you can, but don't for this example), add it to the content-page (.aspx). having the form on the master page means you don't have to manually add a form to content-pages; it's there automatically. (everything on the master page will be on the content-page.)
as masood is showing, search.aspx (the content-page) is using a master page, MasterPageFile="~/MasterPage.master". content goes in the content-tag.
I realised as I am used to hard coding in open source languages, that I was using HTML specific syntax, which was conflicting with the tag surounding the whole masterpage. In using the tools on the side I found my solution.
Thank you.
Well open Visual Studio Click File -> New -> Website -> Empty Web Site.
Create a MasterPage.master and add it to you project.
Example:
<%# Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="MasterPage" %>
<html>
//.......
</html>
Create a SearchPage.aspx and bind it with your master page. Example:
< Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="MasterPage.aspx.cs" Inherits="MasterPage" Title="Untitled Page" %>
I have a master page which has 10 content pages linked to it.
Now a CSS file attached to the Master page gets applied to the content page on its own.
If however, I want a different CSS file only for one of the content pages (and none of the master page CSS should apply to it). How to do it??
You can add that style to a placeholder of the specific page not the masterpage
<%# Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true"
CodeBehind="Detail.aspx.cs" Inherits="Test.Detail" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
<link href="<%= Page.ResolveUrl("~/styles/style.css")%>" type="text/css" rel="stylesheet" />
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
</asp:Content>
A client has an ASP.NET website with master pages and a layout directory.
What we need is 2 different layouts on the site. Can I easily have two layouts with different master pages on the same site?
What's the best way to do that?
See Setting an ASP.NET Master Page at runtime. You can set any page to use any masterpage programmatically at runtime.
Yes. Just create two different master pages and point the corresponding aspx pages to the desired masterpage.
Example:
page1.aspx
<% # Page Language="C#" MasterPageFile="~/Master.master" Title="Content Page 1" %>
<asp:Content ID="Content1" ContentPlaceHolderID="Main" Runat="Server">
Main content.
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="Footer" Runat="Server" >
Footer content.
</asp:content>
page2.aspx
<% # Page Language="C#" MasterPageFile="~/secondary.master" Title="Content Page 2" %>
<asp:Content ID="Content1" ContentPlaceHolderID="Main" Runat="Server">
Main content.
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="Footer" Runat="Server" >
Footer content.
</asp:content>
I have been trying to solve this problem for several weeks now and it is getting really frustrating. Basically i have a simple project which includes one master page and one content page. the following code is what is found in the content page
<%# Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:Button ID="Button1" runat="server" Text="ButtonContent"
onclick="Button1_Click" />
</asp:Content>
The button is bound to a simple event. A break point is set to detect whether the event fired as expected. The event does not fire when a form is placed above the content place holder.
<%# Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="MasterPage" %>
<!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 runat="server">
<title></title>
<asp:ContentPlaceHolder id="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1" runat="server">
<div>
<form></form>
</div>
<div>
<asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</div>
<div>
</div>
</form>
</body>
</html>
however the event is fired when the form is removed or place below the content place holder. On the other hand, on some machines i have found that it does not matter if a form is placed before the content place holder. I have tried this project on 4 machines (three windows 7 and one xp) it has worked regardless of form placement on two machines and has been subject to form placement on the other two.
Could some one please point me to some setting which could solve this problem or offer any advice to solve my problem. I need a form before the content place holder so removing is out of the question. It would also make sense that some sort of setting is preventing the project from working correctly on another machine
per HTML spec, you can not have form inside form. If I remember correctly some browsers break when you have this kind of structure. I think IE works fine.
If you need another form, put it outside of the <form id="form1" runat="server">
- above it, specifically. That is valid.
