Hello,Curious if the Query Task will return overlapping polygons in the same feature layer? I know the Identify Task will do this, but I am working with data that contain relationship classes to SDE tables. From what I've read, the Identify Task is not able to reveal related data, unless I am mistaken.What I am trying to do is select features using a box and returning related attributes to a DataGrid table. So far, I've only been able to pass the top most polygon within the same feature layer and not any underlying polgyons.Your help and suggestions are greatly appreciated!Trent
