Thanks for the response.
What i am essentially after is something similar in concept to kml regions.
i.e Overlay the bingmaps with a grid of squares with each square representing a 100k by 100km radios (for example)
Then depending on the number of nodes in each square, give the square/region a color value (Red for high density)
Then when a user clicks on a square, it would zoom to that "region" and display all the nodes within.
Is there a way todo any of this with the bingmapsprovider ?
I understand you can restrict what nodes get shown based on zoom levels, and that is kinda what i want. but i also want to give users immediate feedback on a world wide map about the density of nodes in each region (i.e each grid), wether it is based on color our some other means (i.e a display of number of nodes within), the user would then click on that region and the camera would zoom in (until the size of the region matches the zoom/screen size). Only then would you display each individual node all around the map)
Hope that makes it a little clearer
EDIT: Just found this example, its basically exactly what i want, only i dont have an ESRI shapefile (only have a collection of nodes from a database)
Is there a way to simulate this behaviour for the bingmapview worldmap (i.e each country would be clickable,and drill down into the nodes for that country.
