I have an application in which user can download the file. I want to open new window while downloading, I mean when user click on download button, page must be redirect on another page and then after download will start. Just like this code project site, when we try on download any file it'll redirect us on another page and then after download will start. Can any one help me out...?? Thanks in advance....

Download link points to a new document. On that document you create a javascript-function which location-href's the user to the actual downloadable file.

<body onload="location.href=''">

  <p>Your download will start in a few seconds</p>


In your case of downloading an image you can add a download.aspx with the following code:

protected void Page_Load(object sender, EventArgs e)
    // Get the full pathname for imagefile
    var imageFilename = Request.QueryString["imgName"];
    var path = Server.MapPath("/Images/" + imageFilename)

    // read the file
    using (FileStream fs = File.OpenRead(path))
        int length = (int)fs.Length;
        byte[] buffer;

        using (BinaryReader br = new BinaryReader(fs))
            buffer = br.ReadBytes(length);

        // Force browser to download rather than open the file in browser
        Response.Buffer = true;
        Response.AddHeader("content-disposition", String.Format("attachment;filename={0}", Path.GetFileName(path)));
        Response.ContentType = "image/jpeg";

<body  önload="location.href='download.aspx?imgFile=nicepicture.jpg'">
  <p>Your download will start in a few seconds</p>
