fpSpread1.Sheets[0].GroupBarInfo.Visible = true;
fpSpread1.Sheets[0].AllowGroup = true;
fpSpread1.Sheets[0].GroupFooterVisible = true;
fpSpread1.Sheets[0].ColumnFooter.Visible = true;
fpSpread1.Sheets[0].ColumnFooter.RowCount = 2;
fpSpread1.Sheets[0].ColumnFooter.Columns[12].HorizontalAlignment = FarPoint.Win.Spread.CellHorizontalAlignment.Left;
fpSpread1.Sheets[0].ColumnFooter.Cells[0, 12].RowSpan = 2;
//Value

for (int r = 0; r < fpSpread1.Sheets[0].RowCount; r++)
{
    for (int j = 0; j < fpSpread1.Sheets[0].ColumnCount; j++)
    {
        fpSpread1.Sheets[0].Models.Data.SetValue(r, j, j + r * fpSpread1.Sheets[0].ColumnCount);
    }
}

int i = 0;
fpSpread1.Sheets[0].ColumnFooter.SetAggregationType(0, 1, FarPoint.Win.Spread.Model.AggregationType.Sum);
fpSpread1.Sheets[0].ColumnFooter.Cells[0, i].Value = "Sum";

private void fpSpread1_Grouping(object sender, FarPoint.Win.Spread.GroupingEventArgs e)
        {
            listBox1.Items.Add("grouping");
        }
