Dynamically changing META Tags in MasterPages from ContentPage

In addition to one of my previous article reference regarding Changing Page Title and Meta Tags with Master Pages.

The earlier method doesn't work in some cases so I was looking for some proper method.
And finally I have found another method of changing meta tag values.

You can visit the following website that describes the content with proper example.

Abstracts:

Firstly, on our MasterPage, we give our meta tags and the page title an ID, and runat attribute:

<title id="PageTitle" runat="server">This is the Default Page Title...</title> <meta name="Keywords" id="PageKeywords" content="default, page, keywords" runat="server" /> <meta name="Description" id="PageDescription" content="This is the Default page desctription, which should be changed when the page is loaded." runat="server" />

Next, we put the following code in MasterPage code-behind:

public string MetaTitle { get { return PageTitle.Text; } set { PageTitle.Text = value; } } public string MetaKeywords { get { return PageKeywords.Content; } set { PageKeywords.Content = value; } } public string MetaDescription { get { return PageDescription.Content; } set { PageDescription.Content = value; } }

The Default.aspx (content page) looks like the following:

<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" Title="Untitled Page" %> <asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server"> Upon loading of this page, the new Page Title, Description and Keywords meta tags should be displayed. You can check this by viewing the browser window title.<br /> <br /> This small area of the page is a content page, the background is the master page. </asp:Content>

Then in the code-behind of Default.aspx we have the following, which will set the meta tags:

using System; using System.Data; using System.Configuration; using System.Collections; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { MasterPage myMaster = (MasterPage)this.Master; myMaster.MetaTitle = "This is the new Page Title, which is set upon Page_Load"; myMaster.MetaDescription = "This is the new Page Description, which is set upon Page_Load"; myMaster.MetaKeywords = "new, page, keywords, set, upon, page, load"; } }
