Hi Sean,

I don't think you can do this with a hierarchical data source that has two bands. It seems to me that what you need here is to use the OutlookGroupBy feature of the grid.

What you could do is bind the grid directly to the orders table (not the Order type). Then you can use OutlookGroupBy to group the grid's only band by OrderType, thus creating the hierarchy you want. Then all you have to do is set HeaderPlacement (on the Override) to FixedOnTop to get the headers displayed once at the top of the grid.

So it would look something like this:

        private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {
            e.Layout.ViewStyleBand = ViewStyleBand.OutlookGroupBy;
            e.Layout.Bands[0].SortedColumns.Add(band.Columns["Order type"], false, true);

            e.Layout.Override.HeaderPlacement = HeaderPlacement.FixedOnTop;       
        }
