Drawing 2D regions on a Map

Ian Jannasch

This should be much easier than what I am experiencing. I think I'm being dumb. Anyway I need to draw complex 2D regions (with holes and may consist of a few areas not physically connected) on a world map in C# winforms, then also get an event triggered when one is clicked(also need to know which one)
I have been using GMapPolygon up until now but this proved to be insufficient because it just builds with lines. I am also aware of the Ggoogle Maps Javascript API, but this does not seem to be free.

Are there any good free libraries that can help me here?

A common requirement for applications utilizing a map control is to allow the end users add pins on the map and draw regions on it. RadMap exposes the necessary API and it can be easily extended with such functionalities.

follow this link, it has both C# and vb.net code snippet given
