Upload Multiple Attachment in Email With Progress Bar Using Uploadify in

We develop a system where users can select multiple files at a time and upload it one by one or in parallel with a progress bar and cancel button near it, simply like a GMAIL style upload system.

Something like:

1. Select multiple files

2. Upload multiple files

How to do this?


This can be done very easily by using a JQuery file upload plug-in called Uploadify which uses flash for rich Ajax like interface.

If you are not familiar with Uploadify here is a description from their web site:
"Uploadify is a jQuery plugin that integrates a fully-customizable multiple file upload utility on your website. It uses a mixture of JavaScript, ActionScript, and any server-side language to dynamically create an instance over any DOM element on a page."
You will need to download the JQuery plugin. Download this plugin from here.
after u download this file, extract this folder and put it in the root folder of your project. I add it into my "_scripts" folder like:

Now Add code in your aspx page ("Default.aspx")

<link href="_scripts/uploadify.css" rel="stylesheet" type="text/css" />
    <script type="text/javascript" src="_scripts/jquery-1.4.4.min.js"></script>
    <script type="text/javascript" src="_scripts/swfobject.js"></script>
    <script type="text/javascript" src="_scripts/jquery.uploadify.v2.1.4.min.js"></script>
    <title>Multiple Upload</title>
    <script type="text/javascript">
        $(document).ready(function () {
                'uploader': '_scripts/uploadify.swf',
                'script': 'Default.aspx',
                'cancelImg': '_scripts/cancel.png',
                'auto': 'true',
                'multi': 'true',
                'buttonText': 'Add Attachment',
                'queueSizeLimit': 5,
                'simUploadLimit': 1,
                'fileExt': '*.pdf;*.txt;*.doc',
                'fileDesc': 'text Files',
                'sizeLimit': 5242880 // The size limit in bytes for each file upload(5MB).
 <form id="form1" runat="server">
 <div id="fuFiles"> 

Add code in Default.aspx.cs

    HttpPostedFile postedFile;
    public string DestinationPath;
    protected void Page_Load(object sender, EventArgs e)
        postedFile = Request.Files["FileData"];
        if (postedFile != null)
            DestinationPath = Server.MapPath("~/Uploads//" + postedFile.FileName);

Download Files  MultipleUploads.rar

It's done just run your Default.aspx page and click on "Add Attachment" button to upload the file.if u face any problem feel free to comment.
