Question

I’m using this code as export to excel from gridview in local machine…..

   void btn_excelClick()
{
 Response.ClearContent();
    Response.Buffer = true;


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

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



    GridView2.RenderControl(htw);
    Response.Write(sw.ToString());
    Response.End();
}

My Question is: How should i modify my code so that the file is downloaded in server side when the end-user clicks on it, and a download link for the source file should pop up.

PS: My Comp is currently my server…

Answer 1

Rather than writing your output to the Response, write it to a file.

Ensure that the path to where you write the file is in a directory that is accessible through IIS.

GridView2.RenderControl(htw);
var path = Server.MapPath("~/PublicFiles/FileName");
File.WriteAllText(path, sw.ToString());

Now you can just write a link to the file in the response, and set the path to this newly created file.
