Im trying to determine if a datawindow contains a group at runtime. All of these scripts don't work. 

ls_band = dw_1.Describe("Datawindow.band.groupheader.height")
ll_groups = Long(dw_1.Describe("Datawindow.Group.Count"))
ls_groups = dw_1.Describe("Datawindow.Groups")

I'm trying to do this in a grid.

I went to Rows/Create group...

---------------------------------------------------------------------------------------------------------------------------

Here is what I am trying to accomplish. 

  1. Determine if the dw contains a group.
  2. Get the columns contained in the group.
  3. Get the sort for the group.
  4. I have a field above each column in my list (below the group) in which you can add the column to the sort.
  5. So I want to append the column sort to the group sort then sort the dw and then call a groupcalc()

Alo, from John's comment below, this may all be for naught because I'm trying to use this in a grid dw.
