Hi
This is probably just a continuation of a previous question on here, but I'm not sure if I get it yet!
I want to load a .SHP or .KML file representing a geography and then have my program supply the values and color the shapes based on information from a database.
For example I would like to load the shape file, color it using a value I have calculated from the database and then overlay an abitrary piece of XAML (which would be a series of other representations of the information for that geographical area). So I would shade the regions based on the number of customers in that region that have some particular characteristic and then overlay a range of other statistics for the region (split by gender as a chart for example).
Is this possible without producing a DBF file? I've no idea how I would do that in these circumstances - I guess I'd have to dynamically serve it but that sounds pretty complex.
Regards
Mike

Hi Mike,
The Colorizer requires an extended data property.
You can set it up from a code for each read shape using the PreviewReadCompleted event. You should specify the MapShapeReader.ExtendedPropertySet property to register necessary property of extended data.
I have attached a sample solution. I hope it helps.

Hi,
I'm trying to apply colorization in the same way you did in the example, but I need it for states and counties in the US. Any help is appreciated.
Thank you, best regards and Merry Christmas :)

Hello awni,
I think the principle of colorization would be the same for any shapefile no matter whether it is a map of Europe, or the US. You can also check this online example here http://demos.telerik.com/silverlight/#Map/DrillDown that demonstrates something similar to your requirement.
