Hi Everyone,

I want to export the gridview data into .csv(comma separated values) file.
I have the code for exporting data into excel file as below:
protected void lnkExport_Click(object sender, EventArgs e)
        string fileName = "attachment;filename=OverallReport_" + DateTime.Now.ToString("dd-MM-yyyy-hh-mm-ss") + ".xls";
        Response.AddHeader("content-disposition", fileName);
        Response.Charset = "";
        Response.ContentType = "application/excel";
        System.IO.StringWriter stringWrite = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
        string s_styleInfo = @"<style> td { mso-number-format:""" + "\\@" + @"""; }</style>";
        string s_excel = stringWrite.ToString();
        Response.Write(s_styleInfo + s_excel);

html code for gridview(gvOverallReport):

<asp:GridView ID="gvOverallReport" runat="server" AutoGenerateColumns="true">
                                           <PagerStyle CssClass="gridPagerStyle" HorizontalAlign="Center" Width="100%" />
                        <SelectedRowStyle CssClass="gridSelectedRowStyle" />
                        <HeaderStyle CssClass="gridHeader" BackColor="#AFB8BF" HorizontalAlign="Left" VerticalAlign="Middle"
                        BorderColor="#bbbbbb" BorderWidth="1px" Font-Bold="True" ForeColor="White" Font-Size="10pt" />
                        <AlternatingRowStyle BackColor="WhiteSmoke" />
                        <PagerSettings Position="TopAndBottom" />
                        <RowStyle CssClass="grdRow" />


Its working perfectly for exporting into .xls file.. But I want a little modification in the same code for exporting into .csv file..
If I change the extension as .csv instead of .xls, its displaying only the html tags in the downloaded file..

Can anyone please suggest me..

Thanks & Regards,
