嵌套 MVC 母版页
我正在使用 MVC 开发 Web 应用程序，并且需要在我的站点中使用嵌套 MasterPage，以便共享可视组件。
我有两个母版页和一个 ContentPage：
- Parent.master
- Child.master
- Content.aspx
我想从以 Child.master 作为 MasterPage 的内容视图引用放置在顶部 Parent.master 上的 ContentPlaceHolder。看来我可以使用直接父级的 ContentPlaceHolders，但不能使用间接父级的 ContentPlaceHolders。让我们看一个示例：
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="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>
结果是我可以看到 Body content 1<我的页面中的 /code> 和 Body content 2，但不是 页面标题。
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="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.

内容占位符仅引用其直接父级中的内容占位符。将您的 Child.master 更改为：
因此 Child.master 本质上就像标题内容占位符的“传递”。
The content place holder will only refer to the content placeholders in its immediate parent. Change your Child.master this this:
So the Child.master essentially acts like a "pass-through" for the Title content placeholder.
我很确定您必须在 child.master
和您的视图中添加标题占位符
I'm pretty sure you have to add your title place holder in your child.master
and in your view
