ASP.NET MVC - How To Design Dynamic H1/Title Scheme?
If i have an ASP.NET MVC 2 Web Application with the following Views:
- Main.aspx
- Page1.aspx
- Page2.aspx
And all Views inherit from a MasterView called Site.master,
I want to be able to have a default Title/H1 for the page, which can be overriden in the deriving Views.
E.g Main.aspx would have "MySite - xxx", Page1.aspx would have "MySite - Page 1", P开发者_StackOverflow社区age2.aspx would have "MySite - Page2".
And if i choose not to set the Title/H1 in a new derived view, the master Title/H1 would be displayed.
With WebForms, i would accomplish this in the following way:
- Make the Title/H1 tags on the master runat="server"
- Expose protected properties on the master code-behind
- On Page_Load of the derived pages code-behind, set the property (Master.Title = "Page 1").
- On Page_PreRender of the master code-behind, set the Title/H1 tags to "My Site - " + Title;
How can we accomplish this with ASP.NET MVC?
I could do this in the master:
<title><asp:ContentPlaceHolder ID="TitleContent" runat="server" /></title>
And then set it in the view:
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
MySite - Page 1
</asp:Content>
But i wanted to be able to only specify "Page 1" in the View, and the title gets magically changed to "MySite - Page 1". Know what i mean? The "MySite - " part of the title needs to be the template for the title.
I'm probably missing something obvious here. :)
With a quick search I found this:
http://haacked.com/archive/2009/04/03/tipjar-title-tags-and-master-pages.aspx
explains why
<title>MySite<asp:content..../></title>
doesn't work
This is how I usually do it:
<title>MySite - <%: Page.Title ?? "Default title" %></title>
in your MasterPage.
Then, you can define the Title
property on a content page like this:
<%@ Page Language="C#"
MasterPageFile="~/Views/Shared/Site.Master"
Inherits="System.Web.Mvc.ViewPage"
Title="Page 1"
%>
Edit:
Well, you might want to see this SO question: ASP.NET MVC - View with master page, how to set title?.
Is much easier as you are describing it.
Just add a content placeholder to your master page
<title>
My Site - <asp:ContentPlaceHolder ID="PageTitle" runat="server" />
</title>
Then in your Content Page use it as
<asp:Content ID="Content3" ContentPlaceHolderID="PageTitle" runat="server">
My Page
</asp:Content>
This way will work but you have to use an HTML HEAD tag, not a server control. So simply remove runat="server"
from your HEAD.
