      GridViewRow row = GridView1.Rows[i]; 

     } 


     GridView1.HeaderRow.Style.Add("background-color", "#e5e1e1");

     Response.Charset = ""; 
     Response.ContentType = "application/vnd.ms-excel"; 
     StringWriter sw = new StringWriter(); 
     HtmlTextWriter hw = new HtmlTextWriter(sw); 
     GridView1.RenderControl(hw); 

     string style = @"<style> .textmode { mso-number-format:\@; } </style>"; 
     Response.Write(style); 
     Response.Output.Write(sw.ToString()); 
     Response.Flush(); 

     Response.End();
