Validating with jQuery

I've been at this for a day now, and I can't get it to work.

How would you validate the controls on the page with the jquery.validate plugin (its firing but nothing is happening), and at the same time, how would I block the server side method from firing if the form is not valid?

my validation.js:

JavaScript

$(document).ready(function() {
    $("#Form1").validate();
    $('#nationalSociety').rules('add', {
        required: true,
        messages: {
            required: 'National Society cannot be empty'
        }
    });
    $('#participantName').rules('add', {
        required: true,
        messages: {
            required: 'Participant Name cannot be empty'
        }
    });
});

add css class for Required fields as "required" . then it will work fine.

<asp:TextBox ID="nationalSociety" runat="server" CssClass="required"></asp:TextBox>

<pre lang="xml"><head runat="server">
    <title></title>
    <script src="jquery-latest.js"></script>
     <script type="text/javascript" src="jquery.validate.js"></script>
    <script>
        $(document).ready(function() {
        $("#form1").validate();
            $('#nationalSociety').rules('add', {
                required: true,
                messages: {
                    required: 'National Society cannot be empty'
                }
            });
            $('#participantName').rules('add', {
                required: true,
                messages: {
                    required: 'Participant Name cannot be empty'
                }
            });
        });
  </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:TextBox ID="nationalSociety" runat="server" CssClass="required"></asp:TextBox>
        <asp:TextBox ID="participantName" runat="server" CssClass="required"></asp:TextBox>
        <asp:Button ID="Button1" runat="server" Text="Button" />

Ah, sorry, I should have explained that the bulk of the controls I'm trying to validate are normal HTML controls, with the exception being the FileUpload control. Thanks though.

Would you know how I can change the look of the validation messages?

OK, now I have another question.

I know how wrong it is to marry stateful and stateless code, but I need to this time due to an insane number of constraints, primarily related to file uploading.

I need to postback through jQuery, so that the fileUpload can start, but now after validation, the page will simply not postback. I've been at it for sometime now, but nothing.

Ideas? Please?
