Convert Graphic (polygon) coordinates

EnriqueIbarra

I have a FeatureSet, result from a query, now I'm triying to highlight the results (polygons) in a graphic layer but need to convert the cordinates of them from Geographic to WebMercator. there's a way to do it?

thanks, sorry can you be a little more clear on how to use the first option?

Should be something like:

  var geometryInWebMercator = new ESRI.ArcGIS.Client.Projection.WebMercator().FromGeographic(geometryInWGS84);

You'll find the documentation here.

If you are using a recent version of the ArcGIS API for Silverlight, the projection to WebMercator coordinates should be done automatically by the graphics layer so you should not have to do it by yourself.

Another option, which avoids the conversion at client side, is to query the graphics directly in the map spatial reference by setting the OutSpatialReference of your query.
