Query same layer w/ overlapping polygons

Question

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!

Ok, last post for this thread as I will be creating a new thread for another, semi related, question.  To follow up this thread though, I was able to figure out that the overlapping polygons were being selected originally and returning values from the polygons underneath. I just created a simple map without the relationshipQuery task for which revealed that the selection function does select multiple/overlapping features.

It seems the way I have the relationshipQuery task scripted, the task is not returning the related values of multiple features.  Here's the link to the new thread http://forums.arcgis.com/threads/21911-relationshipQuery-not-returning-multiple-related-overlapping-features?p=71574#post71574

Thanks for the help!

I am still having a rather difficult time in my efforts to show related data on the dataGrid from a selection box querying overlapping/multiple polygons. I have tried modifying the code many times from other samples to loop through the features, but to no avail.

Are there any example maps or code out there that would point me in the right direction?

Thanks for time!

Thanks for your suggestion. I have combined the "Select Features" and "Query Related Records" examples for my test web application. I am a little confused in where I should put the loop featureSet.features code. Using a function calling esri.toolbars.Draw(map) to draw my selection rectangle, would I add the loop code to this function? Or add the loop code to the function calling a esri.tasks.RelationshipQuery()? Here's my code below: Thanks for your help again! Trent
