Sorry.

You can use the QueryCellStyleInfo event and hide the +/- there.

// Prevent the +/- Icon for an empty row
if (e.TableCellIdentity.TableCellType == GridTableCellType.RecordPlusMinusCell)
{
	Record r = e.TableCellIdentity.DisplayElement.ParentRecord as Record;
	if (r != null && r.ParentTable.TableDescriptor.Name != DataSetBuilder.SALESTRANSACTION_LIST 		
						&& r.NestedTables.Count > 0 && r.NestedTables[0].ChildTable.GetFilteredRecordCount() == 0)
	{
		e.Style.CellType = "Static";
	}
}
