To export your grid data

public static void ExportToExcel(string strFileName, GridView dg)
           int row = dg.Rows.Count;
           HttpContext.Current.Response.AddHeader("content-disposition", "attachment; filename=" + strFileName + System.DateTime.Now.Hour + "_" + System.DateTime.Now.Minute + ".xls");
           HttpContext.Current.Response.ContentType = "application/excel";
           System.IO.StringWriter sw = new System.IO.StringWriter();
           HtmlTextWriter htw = new HtmlTextWriter(sw);
       catch(Exception ex)

and add these lines as it is to verify rendering of control

public override void VerifyRenderingInServerForm(Control control)
       /* Verifies that the control is rendered */

Now In your .aspx file in <%@page .... %> add atributes

AutoEventWireup="true" EnableEventValidation="false"

this works for me hope will help you too .. happy coding :-)

make it to your lowest version like say take 2003 excel sheets extension. I think the lower version files can be opened on higher version Application. give it a try.
