In an application i have written this code for downloading a file:

C#

try
            {
                string strURL = " Mandatory Disclosure-20101.doc";
                WebClient req = new WebClient();
                HttpResponse response = HttpContext.Current.Response;
                response.Clear();
                response.ClearContent();
                response.ClearHeaders();
                response.Buffer = true;
                response.AddHeader("Content-Disposition", "attachment;filename=\"" + Server.MapPath(strURL) + "\"");
                byte[] data = req.DownloadData(Server.MapPath(strURL));
                response.BinaryWrite(data);
                response.End();
            }
            catch (Exception ex)
            {
            }

This code working properly but it is downloading the file directly.
I want to prompt a dialogue box which asks to save or to open the file?

Try this method .i think this will help you

C#

private void DownloadFiles()
    {
        string filePath = "";
        if (Convert.ToString(Request.QueryString["module"]) == "INV")
            filePath = Server.MapPath("~") + Convert.ToString(ConfigurationSettings.AppSettings["Upload"]) + Convert.ToString(Request.QueryString["fileName"]); //@"E:\NewFolder\MRP_20100311.xls";
        try
        {
            if (File.Exists(filePath))
            {
                FileInfo objFileInfo = new FileInfo(filePath);
                WebClient client = new WebClient();
                Byte[] buffer = client.DownloadData(filePath);
                Response.Clear();
                Response.ContentType = GetContentType(objFileInfo.Extension); //"application/ms-excel";
                Response.AddHeader("content-disposition", "Attachment;filename=" + objFileInfo.Name); //content-length", buffer.Length.ToString());
                Response.BinaryWrite(buffer);
                Response.End();
            }
        }
    }
private string GetContentType(string strExt)
    {
        //strExt = strExt.ToUpper();
        string type = "";
        if (strExt != null)
        {
            switch (strExt.ToLower())
            {
                case ".htm":
                case ".html":
                    type = "text/HTML";
                    break;
                case ".txt":
                    type = "text/plain";
                    break;
                case ".xml":
                    type = "text/xml";
                    break;
                case ".doc":
                case ".docx":
                case ".rtf":
                    type = "Application/msword";
                    break;
                case ".xls":
                case ".xlsx":
                case ".csv":
                    type = "Application/ms-excel";
                    break;
            }
        }

        if (type == "")
            return "APPLICATION/OCTET-STREAM";
        return type;
    }
