Derrick VanArnam and Russell Fox have developed a sample Access database that shows how to integrate Silverlight into an Access database. The sample demonstrates interoperability between Access and a Silverlight Treeview control, but you can also use other Silverlight controls, such as the Treeview, DataGrid, Video, and charts.
The basic method is to place an Access Web Browser Control onto a form, and then load an HTML page containing the Silverlight control. Read the full post and download the sample!
