Hi Mahalakshmi Ravi,
Thank you for contacting us.
ShapeFile / SQL 2008 Geospatial data support is in our extended TODO list but it is unlikely that we will be able to include it for the first official release of RadMap for Q1 2010 around March (currently the control is in CTP stage). Nevertheless, we will forward your feedback to our developers so they can consider it when planning the features for the Q2 2010 release.
At the moment the control supports KML data import only.
