When trying like below method..AAddOn is displayed at first..

How can we display the command field at the last..

              <HeaderStyle CssClass="AAddOn" />
             </asp:CommandField>
      </asp:GridView>

For gridview, defined columns always render first then the auto generated columns render on the right side of it. To move auto generated columns to left side, you need RowCreated event. There you can manipulate the order of columns as required. You can use below code.

protected void AGridView_RowCreated(object sender, GridViewRowEventArgs e){
        List<TableCell> cellColumns = new List<TableCell>();
        foreach (DataControlField column in GridView1.Columns)
        {
            TableCell cell = e.Row.Cells[0];
            e.Row.Cells.Remove(cell);
            cellColumns.Add(cell);
        }

        e.Row.Cells.AddRange(cellColumns .ToArray());
}
