gridview 模板里绑定多个参数

经常会遇到gridview绑定多个参数，头都大，简单点

  protected void GridViewRowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                         string url = "openNewWindow('ProductSell.aspx?id=" + e.Row.Cells[0].Text + "," + e.Row.Cells[4].Text + ",0')";
                    btnSell.Attributes.Add("onclick", url);
                
                
                          
            }
        }
