I need to get a count of all items each time a group changes, for example:

year 2008: 100
  month January 3
  record 1
  record 2
  record 3
  month February 5
  record 4
  record 5
  record 6
  record 7
  record 8

etc
I have this code, but it only gets the group header having children records, and not the top level (year)

 foreach (GridGroupHeaderItem groupHeader in rgTickets.MasterTableView.GetItems(GridItemType.GroupHeader))
            {

                Created = Closed = 0;
                GridItem[] children = groupHeader.GetChildItems();
                try
                {
                    foreach (GridItem child in children)
                    {
                        GridDataItem dataItem = child as GridDataItem;
                        Created += Convert.ToInt32(dataItem["Created"].Text);
                        Closed += Convert.ToInt32(dataItem["Closed"].Text);
                    }

                    // strCount = children.Sum(n => Convert.ToInt32(n.Cells[5].Text));
                    groupHeader.DataCell.Text += "    Created:  " + Created.ToString();
                    groupHeader.DataCell.Text += "    Closed:  " + Closed.ToString();

                }
                catch (Exception ex)
                {

 

                }
              

            }

Hello Zed,

Another possible option in this case would be to use the footer aggregates, where you can include the Count aggregate, showing all the items within the group automatically.

I came to the same conclusion independently.  It shows great minds work alike :).  I opened a thread on that subject and Pavlina answered.
