Duplicate title tags using ASP.NET MasterPage

asp.net, master-pages, title

Solution

The header of your .master needs to look like this:

<head runat="server">
<title>Default Title</title>
  .. other tags
</head>

Then in your page code-behind in the Page_Load, you write:

protected void Page_Load(object sender, EventArgs e)
{
    this.Title = "My Page Title";
}

Problem

I need to set the title of a page dynamically, and so I use code similar to the following: ``` <%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="~/about.aspx.cs" Inherits="Default" %> <%@ Register Assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="ajaxToolkit" %> <%@ MasterType VirtualPath="MasterPage.master" %> <%@ OutputCache Duration="43200" VaryByParam="*" Location="Server" %> <asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server"> <title><%=pageTitle%></title> </asp:Content> ``` But this generates duplicate title tags. Is there any way I can get around this? Thanks. EDIT: Following from the suggestions below, I now have the following in my MasterPage: ``` <head id="Head1" runat="server"> <title>Default Title</title> ... <asp:ContentPlaceHolder id="head" runat="server"> </asp:ContentPlaceHolder> </head> ``` and the following in my primary page: ``` this.Title="xxx"; ``` but I'm not getting any title (neither "Default Title" nor "xxx"). EDIT: Nevermind. Got it working using that method.
