following sample http://resources.esri.com/help/9.3/arcgisserver/apis/silverlight/samples/start .htm#MapItSpatialQuery, and i am trying use these for points on map. polygon and rectacle work well, but when i try use line doesnt work, is a Draw bug with points?i tried use many SpatialRelationship(contains,touchs,intersect etc..), but no sucess with this.
This is not a bug, it is difficult if not impossible to be able to query by point with exact precision. (Point selection against exact Point geometry in the layer).
