I add the following Delete button to the grid column.  However, the button is also added to the "new row" template.  It should only be added to the data rows.  I tried several things to set the style of the cell in InitializeRow when e.Row.IsAddNew, but nothing has helped.

using (GridColumnConfig columnConfig = new GridColumnConfig(gridBand))
{
  UltraGridColumn col = columnConfig.Add(c_sDeleteColKey, string.Empty, 0);
  col.ButtonDisplayStyle = Infragistics.Win.UltraWinGrid.ButtonDisplayStyle.Always;
  col.CellButtonAppearance.Image = Properties.Resources.Office2003Delete_black_;
  col.CellButtonAppearance.ImageHAlign = Infragistics.Win.HAlign.Center;
  col.FilterOperandStyle = FilterOperandStyle.None;
  col.Style = Infragistics.Win.UltraWinGrid.ColumnStyle.Button;
  col.MaxWidth = 25;
  col.MinWidth = 25;
}
