Hi Amy,

You can do something like this:

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

            band.Columns[0].Width = 100;
            band.Columns[0].MinWidth = 100;
            band.Columns[0].MaxWidth = 100;

            band.Columns[2].Width = 100;
            band.Columns[2].MinWidth = 100;
            band.Columns[2].MaxWidth = 100;

            layout.AutoFitStyle = AutoFitStyle.ResizeAllColumns;
        }
