Nested MVC master pages
I'm, using MVC to develop a Web application, and I need to use nested MasterPages in my site, in order to share the Visual Components.
I have two Master Pages and a ContentPage:
- Parent.master
- Child.master
- Content.aspx
I want to reference a ContentPlaceHolder placed on the top Parent.master from the Content view that has Child.master as MasterPage. It seems that I can use the ContentPlaceHolders from the direct parent, but not from the indirect parent. Let's see with a sample:
Parent.master
<%@ Master Language="C#"
Inherits="System.Web.Mvc.ViewMasterPage"%>
<HTML>
<head runat="server">
<title>
<asp:contentplaceholder id="Title" runat="server" />
</title>
</head>
<body>
<asp:contentplaceholder id="Body" runat="server" />
</body>
<HTML>
Child.Master
<%@ Master Language="C#" MasterPageFile="~/Views/Shared/Parent.master"
Inherits="System.Web.Mvc.ViewMasterPage"%>
<asp:Content ID="BodyContent" ContentPlaceHolderID=开发者_StackOverflow中文版"Body" runat="server">
<asp:contentplaceholder id="Body1" runat="server" />
<asp:contentplaceholder id="Body2" runat="server" />
</asp:Content>
Content.aspx
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Child.master"
Inherits="System.Web.Mvc.ViewPage" %>
<asp:Content ID="TitleContent" ContentPlaceHolderID="Title" runat="server">
<!-- Placed to the top parent Master page (does not work) -->
The page title
</asp:Content>
<asp:Content ID="Body1Content" ContentPlaceHolderID="Body1" runat="server">
<!-- Placed in the direct parent Master page (Works) -->
Body content 1
</asp:Content>
<asp:Content ID="Body2Content ContentPlaceHolderID="Body2" runat="server">
<!-- Placed in the direct parent Master page (Works) -->
Body content 2
</asp:Content>
The result is that I can see Body content 1 and Body content 2 in my page, but not the page title.
The content place holder will only refer to the content placeholders in its immediate parent. Change your Child.master this this:
<%@ Master Language="C#" MasterPageFile="~/Views/Shared/Parent.master" Inherits="System.Web.Mvc.ViewMasterPage"%>
<asp:Content ID="BodyContent" ContentPlaceHolderID="Body" runat="server">
<asp:Content ContentPlaceHolderID="Title" runat="server">
<asp:contentplaceholder id="TitleContent" runat="server" />
</asp:Content>
<asp:contentplaceholder id="Body1" runat="server" />
<asp:contentplaceholder id="Body2" runat="server" />
</asp:Content>
So the Child.master essentially acts like a "pass-through" for the Title content placeholder.
I'm pretty sure you have to add your title place holder in your child.master
<%@ Master Language="C#" MasterPageFile="~/Views/Shared/Parent.master"
Inherits="System.Web.Mvc.ViewMasterPage"%>
<asp:Content ID="TitleContent" ContentPlaceHolderID="Title" runat="server" />
<asp:Content ID="BodyContent" ContentPlaceHolderID="Body" runat="server">
<asp:contentplaceholder id="Body1" runat="server" />
<asp:contentplaceholder id="Body2" runat="server" />
</asp:Content>
and in your view
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Child.master"
Inherits="System.Web.Mvc.ViewPage" %>
<asp:Content ID="TitleContent1" ContentPlaceHolderID="TitleContent" runat="server">
<!-- Placed to the top parent Master page (does not work) -->
The page title
</asp:Content>
<asp:Content ID="Body1Content" ContentPlaceHolderID="Body1" runat="server">
<!-- Placed in the direct parent Master page (Works) -->
Body content 1
</asp:Content>
<asp:Content ID="Body2Content ContentPlaceHolderID="Body2" runat="server">
<!-- Placed in the direct parent Master page (Works) -->
Body content 2
</asp:Content>
