I have several content pages hanging off of one master page. I need to add a refresh meta tag to one of the content pages but I can't see where I can do this.
Any help would be much appreciated.
Have not tried this with refresh, but in general you can add a meta tag like this:
var keywords = new HtmlMeta { Name = "keywords", Content = "one,two,three" };
Header.Controls.Add(keywords);
update: it is possible this way. Check Rick Strahl http://www.west-wind.com/weblog/posts/2006/Aug/04/No-more-Meta-Refresh-Tags
This page explains the new feature: ASP.Net 4 adds 2 new Meta tag related properties to the Page. They can be used to set meta tags for keywords and description.
You can set them in the code behind:
Page.MetaKeywords = "keyword1, keyword2, keyword3";
Page.MetaDescription = "Example of new meta tag support in ASP.Net 4";
You can also set in the @Page directive:
<%@ Page Language="C#" AutoEventWireup="true"
MetaKeywords="keyword1, keyword2, keyword3"
MetaDescription="Example of new meta tag support in ASP.Net 4"
CodeFile="Default.aspx.cs" Inherits="_Default" %>
The ouput of either of these methods renders html similar to the following:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>
ASP.NET 4 Meta Tag Support
</title>
<meta name="description" content="Example of new meta tag support in ASP.Net 4" />
<meta name="keywords" content="keyword1, keyword2, keyword3" />
</head>
<body>
</body>
</html>
protected void Page_Load(object sender, EventArgs e)
{
Page.Title = "Title of page";
HtmlMeta tag = new HtmlMeta();
tag.Name = "description";
tag.Content = "description of page";
Header.Controls.Add(tag);
HtmlMeta tagKeyword = new HtmlMeta();
tagKeyword.Name = "keywords";
tagKeyword.Content = "keywords of page";
Header.Controls.Add(tagKeyword );
}
One way I found to do this (that I didn't see listed here) was to have a Literal and fill it with whatever kinds of meta tags you want. In my case, I needed to use it without a Master page, to have Facebook recognize a thumbnail image, title, and description:
<head runat="server">
<asp:Literal runat="server" ID="litMeta" />
...
</head>
CodeBehind:
var img = "<meta property=\"og:image\" content=\"thumbnail.jpg\" />";
var title = "<meta property=\"og:title\" content=\"Title\" />";
var desc = "<meta property=\"og:description\" content=\"Description\" />";
litMeta.Text = img + title + desc;
