cluster with attributes

[JoseLuis_Serrano]

Hi,

I need to cluster a point layer but the resulting cluster can't have points with different values for a given attribute. For instance, if I am clustering cities in Europe, the clusters in one country can't contain cities from a different country. I was looking around and I found this:

That it is exactly what I need but in Flex, and I haven't found anything similar in Silverlight.

Has someone done something similar? Are the Flex and Silverlight API similar enough to try implement the Flex solution in Silverlight?

Thanks a lot,
