Styling The File Upload 'Browse' Button

Question

I have an asp.net website which is using Bootstrap and on one page I have a file upload field. Now I know this has been asked may times before but I cant seem to find a solution for asp.net.

Ideally what i'm after is to style the file upload 'Browse' button so it's just a file glyphicon so looking at the Bootstrap site I would like to use something like

What I'm after it looking like (take from Bootstrap website)

<div class="input-group">
     <input type="text" class="form-control" placeholder="Username" aria-describedby="basic-addon1">
     <span class="input-group-addon" id="basic-addon1">
          <i class="glyphicon glyphicon-folder-open"></i>
     </span>
</div>

So I would have the input field with the folder icon at the end of it but I can't seem to find a way to do this and was wondering if anyone else could help.

My current code is:

<div class="form-group">
     <asp:Label ID="Label3" class="col-md-3 control-label" runat="server" Text="Upload"></asp:Label>
     <div class="col-md-3">
          <asp:FileUpload ID="fuAttachment" runat="server" class="fileupload"></asp:FileUpload>
     </div>
</div>

And my custom CSS is

.fileupload
{
    font-family: inherit;
    font-size: inherit;
    line-height: inherit;
    width: 100%;
    height: 32px;    
    pointer-events: none;
}

Have you already done some research? Because Google's first result gives me the perfect solution. — aley

@AlexG Yes I did but it's not the solution I'm after as I want it to be displayed as I mentioned in my initial post but just to double check, could you provide the link you found just in case I missed it or I searched for something completely different — murday1983

@Amitsingh There are a few suggestions in my post which may also help you. In particular the answer provided by vanburenx as the snippet seems to be exactly what I'm looking for — murday1983

@murday1983 Of course: geniuscarrier.com/… I've use a similar tutorial when I learned html, css and bootstrap. — aley

Don't suppose you know exactly what I need from the "maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" do you as when I reference this file it completely trolls all over my .css files
Worked great. Made a few .css changes to gray out the input and also replaced wording with glyph's but other than that it worked

You can try like this: Demo

Used Bootstrap buttons for styling upload button.

.fileUpload {
    position: relative;
    overflow: hidden;
    margin: 10px;
}
.fileUpload input.upload {
    position: absolute;
    top: 0;
    right: 0;
    margin: 0;
    padding: 0;
    font-size: 20px;
    cursor: pointer;
    opacity: 0;
    filter: alpha(opacity=0);
}
