Editing Meta Tags From Code Behind

Dynamically change the content of meta tags from the code behind. This allows you to feed the meta tags with content from a database or other dynamic content.

In your aspx source code do:

<meta id="metaDescription" name="description" content="" runat="server" />

In your aspx code behind do:

metaDescription.Content = "Description goes here"

The key is the runat="server" and the unique id within the meta tag. This allows you to "see" it in your code behind and manipulate it before sending it to the browser.
