Implementing a timeline slider using silverlight or ajax?

I want to ask you for direction for creating a timeline slider similar to the one in Plurk.

I want to arrange my events on a timeline and make the user slide through this time line to navigate the events.

I just want to know weather I can do it using silverlight or not ? or any other feature in the .NET platform.

Thanks!

You can definitely do one in Silverlight by styling the ListBox control. You would modify the ItemsPanel and ItemTemplate in Expression Blend to do so - you would also need to create a ValueConverter to position the timeline items. Although this article was written about WPF, you can now do all of the things in it with Silverlight. The article gives a good idea of what you would do and how you would do it.
