Gridview to Excel file - save output instead of showing it

Question

I have this code below which takes my GridView, populates it, and generates and opens an Excel file with the griddata in my browser.

What if I want to save that file directly to my server or attach it to an email message, instead of the display prompt that automatically pops up.

Can I do that with small modifications to the script?

protected void btnExcelExport_Click(object sender, EventArgs e) 
{ 
    HtmlForm form = new HtmlForm(); 

    Response.Clear(); 
    Response.Buffer = true; 
    Response.Charset = ""; 
    Response.AddHeader("content-disposition", string.Format("attachment;filename={0}", "Student.xls")); 
    Response.ContentType = "application/ms-excel"; 

    StringWriter sw = new StringWriter(); 
    HtmlTextWriter hw = new HtmlTextWriter(sw); 

    GridView1.AllowPaging = false; 
    BindGridDetails(GridView1); 

    form.Attributes["runat"] = "server"; 
    form.Controls.Add(GridView1); 
    this.Controls.Add(form); 
    form.RenderControl(hw); 

    string style = @"<!--mce:2-->"; 
    Response.Write(style); 
    Response.Output.Write(sw.ToString()); 
    Response.Flush(); 
    Response.End(); 
}

Answer 1

you can save your grid data as a Comma Separated Value file on the server and email or save it directly on your server. CSV files can be opened using Excel.
