Hello Vivek,

although I have not done this, it should work this way.

  • after map is refreshed, perform ExecuteIntersectionQuery on the Marker layer with the bounding box of the current map.
  • assuming you don't have to many markers place some image controls on your map using map.WorldToImage() function, set featuredatarow as tag property.
  • register click event for each of these imagecontrols and then you can handle that to show a balloon tip with the contents of the featuredatarow.
