Hi Maria,

Yes, I'm sure you can do this and it should be very easy. The only question I have is... what happens if there is more than one child row under a particular parent row?

Assuming that your data source only has one child row for each parent row, then you could achieve what you want by adding an unbound column to band 0.

        private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {
            UltraGridLayout layout = e.Layout;
            UltraGridBand band = layout.Bands[0];

            if (false == band.Columns.Exists("My unbound column"))
            {
                UltraGridColumn column = band.Columns.Add("My unbound column");                
            }            
        }

Then you use the InitializeRow event to read the data from the child row and populate the cell in the parent row:

        private void ultraGrid1_InitializeRow(object sender, InitializeRowEventArgs e)
        {            
            // if the unbound column has not been added to the grid, yet, then just bail out.
            if (false == e.Row.Cells.Exists("My unbound Column"))
                return;

            // Is this the root band?
            if (e.Row.Band.Index == 0)
            {
                e.Row.Cells["My unbound Column"].Value = e.Row.ChildBands[0].Rows[0].Cells["Whatever Cell I want"].Value;
            }
        }
