custom paging in silverlight 3.0

Hi Guys,
Does anyone have any sample code for custom paging in silverlight 3.0. The paging should be similiar as like as this forum paging i.e it sld have
next 1|2|3 prev , next 1|2|3 prev, next 1|2|3 prev , next 2|3|4 prev
The paging size should be fixed to 3 page and it should increment when page grows.
Any help please.
Thanks
