Silverlight: United States Map ListBox

Recently, one a Silverlight POC, my team built a Map Area Control. This control constructs a zoom-able, pan-able vector map of geo-political territories. The particular domain we used was the United States. We setup an XML Data File that contains the rendering instructions for each state such as X, Y, Width, Height and Path, then we used Linq—>XML to construct entities from the XML.

<MapArea Description="Idaho" ShortName="ID" Left="107.588" Top="44.55" Width="72.6835" Height="116.451" Path="…"/>

This Map control is really a ListBox that exposes a collection of selected states. The ListBox ItemTemplate consists of a RadioButton that has been re-skinned with a Path that is bound to the properties we pulled from the XML data island.
