I have page called filedownload.aspx , it contains grid and in grid they are three columns and in one of the column there is button which says Download , when user clicks on that button it picks file id and gives the download box to user with three options Open save and cancel .

Now the problem is that when user clicks on the download button in grid it gives this ERROR: INTERNET EXPLORER CANNOT DOWNLOAD FILEDOWNLOAD.ASPX FROM ABC.XYZ.COM (MY URL EXAMPLE) INTERNET EXPLORER WAS NOT ABLE TO OPEN THIS SITE .THE REQUEST SITE IS EITHER UNAVAILABLE OR CANNOT BE FOUND .

我的《手法》:

protected void gdvfiledownload_RowCommand(object sender, GridViewCommandEventArgs e) { try { if (e.CommandName == "Download") { int indexfile = Convert.ToInt32(e.CommandArgument.ToString()); GridViewRow row = gdvfiledownload.Rows[indexfile]; string fileuserid = Ldapinfo.getName(Page.User.Identity.Name); string batchfilename = Convert.ToString(row.Cells[0].Text.ToString()); //string requestedby = Convert.ToString(row.Cells[3].Text.ToString());

            SqlConnection cn = new SqlConnection(ConfigurationManager.ConnectionStrings["connectionstring"].ConnectionString.ToString());
            cn.Open();
            con = new SqlConnection(ConfigurationManager.ConnectionStrings["connectionstring "].ConnectionString.ToString());
            con.Open();
            DataSet ds = new DataSet();
            //SqlDataAdapter da = new SqlDataAdapter("sp_Insert_CAV2_File", cn);
            SqlCommand sqlCommand = new SqlCommand("sp_proc ", cn);
            sqlCommand.CommandType = CommandType.StoredProcedure;
            sqlCommand.Parameters.AddWithValue("@batch_name", batchfilename);
            sqlCommand.Parameters.AddWithValue("@curr_user", fileuserid);
            SqlDataAdapter da = new SqlDataAdapter(sqlCommand);
            da.Fill(ds);
            StringBuilder  strFD = new StringBuilder();
            for (int i = 0; i <= ds.Tables[0].Rows.Count - 1; i++)
            {
                for (int j = 0; j <= ds.Tables[0].Columns.Count - 1; j++)
                {
                    strFD.Append(ds.Tables[0].Rows[i][j].ToString());
                    strFD.Append(" ");
                }
                strFD.AppendLine();
            }

            Response.Clear();
            Response.AddHeader("content-disposition", "attachment;filename=Notepad.txt");
            Response.Charset = "";
            Response.Cache.SetCacheability(HttpCacheability.NoCache);
            Response.ContentType = "application/vnd.text";
            System.IO.StringWriter stringWrite = new System.IO.StringWriter();
            System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);

            Response.Write(strFD.ToString());
            Response.End();
            cn.Close();
            con.Close();
            cn.Dispose();
            con.Dispose();
        }
    }
    catch (Exception ex)
    {
        lblfilemess.Text = ex.Message.ToString();
    }
}
