    Only add this CSS to your code. It simply hide the "No file chosen".

    <style>
     input[type=file]
    {
    width:90px;
    color:transparent;
    }
    
    </style>

    You replace the text with your own message using CSS pseduo-class :after. You can declare a class like this one:

    .bar:after {
        content:"Please select a file";
        background-color:white;
    }
    

    And assign it to your FileUpload control. The content message will replace the original one. Of course upon file selection you need to remove the message, you can do this for example via jQuery .removeClass (assuming ID of your FileUpload is "foo"):

    $('#foo').change(function() {
        $(this).removeClass("bar");
    })

    Note that this solution seems to work Webkit-browser's only (Chrome, Opera, Safari) you may need an alternative for others.

    input[type=file]{
      color:transparent;
    }
    input[type=file]:after {
      color: #000;
      content:" Cool!";
    }
    

    Improvements over other solutions:

    • Works for short text
    • Doesn't change the background color
    • Pure css

    This work in all browser

    window.pressed = function(){
        var a = document.getElementById('aa');
        if(!(a.value == ""))
        {
            var theSplit = a.value.split('\\');
            fileLabel.innerHTML = theSplit[theSplit.length-1];
        }
    };
    input[type=file]{
        width:90px;
        color:transparent;
    }

    See above link. I use css to hide the default text and use a label to show what I want:

    html

    <div>
          <input type='file' title="Choose a video please" id="aa" onchange="pressed()">
          <label id="fileLabel">Choose file</label>
    </div>
    

    css

    input[type=file]{
        width:90px;
        color:transparent;
    }
    

    javascript

    window.pressed = function(){
        var a = document.getElementById('aa');
        if(a.value == "")
        {
            fileLabel.innerHTML = "Choose file";
        }
        else
        {
            var theSplit = a.value.split('\\');
            fileLabel.innerHTML = theSplit[theSplit.length-1];
        }
     };

    If you visit your page source in your browser ASP.NET put an input element with type='file' instead of your FileUpload. You could simply use CSS to cover the text with something when the value attribute is empty.
