Is there a method to determine if a named (derived) BOM row is hidden?  There doesn't seem to be one and my program is outputting all rows, hidden or not.

code snippet:

Dim ppoRows() As Object = Nothing

Dim ppoRow As IEdmBomCell

bomView.GetRows(ppoRows)

i = 0

              arrSize = ppoRows.Length

                str = ""

               While i < arrSize

                  ppoRow = ppoRows(i)

                  str = "BOM Row " & i & ": " & vbLf & "Item ID: " & ppoRow.GetItemID & vbLf & "Path name: " & ppoRow.GetPathName & vbLf & "Tree level: " & ppoRow.GetTreeLevel & vbLf & " Is locked? " & ppoRow.IsLocked

                  MessageBox.Show(str)

                  i = i + 1

               End While

edmbomcell doesn't have a lot of methods and rows are just system objects.  I'm at a loss here.
