Hello Vivek Kumar,

You need to follow these steps:

  1. Depending on your database pick a suitable provider
    • SqlServer2008
    • PostGis
    • SpatiaLite
    • Shapefile
    • ...
  2. Add a VectorLayer to your map
    var pointLayer = new VectorLayer("GeoLocations", new ...Provider(<...Provider arguments>);
    ((VectorStyle)PointLayer.Style).Symbol = <Load some symbol>;
    map.Layers.Add pointLayer;
  3. Add map to MapBox|Image control
  4. Set ActiveTool for MapBox|Image to 'Query'
  5. Handle MapQueried event to setup ToolTip
