We are programatically creating a Hierarchy Grid with multiple levels on it.
Inorder to hide the Plus image for the items that don't have sub levels we are actually hiding the plus image in the item databound event by checking a "Count" variable that would be populated on the need datasource and detail table bind events.
Everything works fine except for an issue
Assume there are two items,
one with a plus image as it has 3 child items
another item without plus iomaghe as it doesn't have any child item
When I click the plus image of the first item its displays the 3 items below it.At the same time its adding a plus image on the second item as well.This ideally should not happen as it doen't have any child items.

When i click the first item the detail tabel bind is called to load the 3 child items.
Iam not sure why the second item is also updated
Based on this information, it is hard to determine what is causing this behavior. If the issue persists, you can open a formal support ticket, and send us a small working project, demonstrating your logic, and the unwanted behavior. We will review it locally, and advise you further.
