Hi Harish, 
  
 Thanks for your post and welcome to MapSuite World, do you mean get the text column from GdiPlusGeoCanvas class, If yes, I am sorry to say that there isn’t a existing API to get it for now. If not would you please give us more information about your scenario,

Dear Sir,



 My text  column add process given below 



 ShapeFileFeatureLayer austinStreetsLabelLayer = new ShapeFileFeatureLayer(@"…\SampleData\Data\austinstreets.shp");
            austinStreetsLabelLayer.ZoomLevelSet.ZoomLevel01.CustomStyles.Add(TextStyles.LocalRoad1("FENAME"));
            austinStreetsLabelLayer.ZoomLevelSet.ZoomLevel01.ApplyUntilZoomLevel = ApplyUntilZoomLevel.Level20;




LayerOverlay staticOverlay = new LayerOverlay();
          staticOverlay.Layers.Add("AustinStreetsLabelLayer", austinStreetsLabelLayer);
            winformsMap1.Overlays.Add(staticOverlay);


winformsMap1.CurrentExtent = new RectangleShape(-97.749141617693908, 30.300592918607943, -97.741202279009826, 30.29492809316849);
