To reproduce: - Create a shape with QGIS and add it to RadMap using the approach described in the documentation: http://docs.telerik.com/devtools/winforms/map/file-readers/esri-shapefile-reader
This is complex issue which will require a lot of development. It is in our list but, unfortunately, I cannot provide you with a time frame.
Not Scheduled ? RadMap with ESRi shapefiles Is unusable in this condition.
