Using VEMap to color a region

Question

Using visual web developer express 2010, I want to display a shape file and be able to manipulate the colors of the regions specified by that shape file based on some data values.

I found some code (I think it was an MSDN page) that throws up a simple map on to the screen of a web page. Here it is:

 <script type="text/javascript" src="http://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.3"></script>

  <script type="text/javascript">
      var map;

      function OnPageLoad() {
          map = new VEMap('myMap');
          map.LoadMap();

      }
  </script>

<body onload="OnPageLoad();">
  <div id="myMap" style="position:relative;width:640px;height:480px;"></div>

It doesn't use a shapefile, per se, but something online that it's pointing to (Virtual Earth). that's okay, that might work, but ...

It displays a map with some basic control mechanisms (pan, zoom, etc.). I copy-pasted this into a web page and it works well. I want to be able to color regions on this map based on some values. I figure there's got to be some kind of underlying structure to this thing (an object model) that contains references to the regions, etc. But I can get any help from intellisense in visual web developer express 2010.

Anyone have an idea how to do this?

Meanwhile, back to searching the web.

Solution

In 6.3 I believe you do this with the VEShape Class.

Here are the classes supported for 6.3.

These are some great examples to get you started. Although a lot of them are version 7.0 but the syntax is quite similar. If your having troubles converting, here is a nice migration from 6.3 to 7.0 provided by msdn.
