Facebook Style "Like" button without postback
<p>How would one go about creating a facebook-style "Like" button in C# ASP.NET without doing a postback? Are there any code examples or tutorials that you know of? I assume that would have to use asynchronous javascript. (this is a tough one to search for due to the Facebook keyword!)</p>

<p>This would have to work with .NET 2.o framework, SQL Server 2005 and VS 2005.</p>

<p>Thanks for any direction.</p>
