Hi,

You can add an unbound column to the grid using the Add method on the Columns collection.

Why does it have to be added after InitializeLayout? In most cases, I would recommend adding the column inside the InitializeLayout event. But it's pretty much the same either way:

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

            UltraGridColumn imageColumn = band.Columns.Add("My Image Column");
            imageColumn.DataType = typeof(Image);
            imageColumn.Style = Infragistics.Win.UltraWinGrid.ColumnStyle.Image;
        }

Outside of InitializeLayout, you would just use grid.DisplayLayout instead of e.Layout.

And then you would probably want to use the InitializeRow event to populate the image column with a value.

[code]

        private void ultraGrid1_InitializeRow(object sender, InitializeRowEventArgs e)
        {
            if (e.Row.Cells.Exists("My Image Column"))
            {
                e.Row.Cells["My Image Column"].Value = someImage;
            }
        }
