Hello,

Is there a way to highlight part of a country/state/county border? Say I want to highlight the coastal border of Florida, or the border from one lat/lon poinr to another. Is there anything in place to do something like that?

Thanks,  
Dib

Hi Dib,

Highlight the border of a state should be easier, because you can directly read the shape from data, then highlight it.

If you want to highlight a point to another, you need to do spatial query, and maybe you cannot get the result you want.

Please refer this sample which shows how to highlight a polygon: [https://github.com/ThinkGeo/HighlightAtMouseHoverSample-ForWpf](https://github.com/ThinkGeo/HighlightAtMouseHoverSample-ForWpf)
