It\'s basically what the title says.. I have a form with a select control that I want to force the form to post back to self on change. 

$bmsclientlist = $cl

    a quick fix is this:

    Add an onchange attribute to your selectlist

    <select name="bmsid" onchange="javascript: form.submit();">

    This is a <select> that will submit the parent form

    <form method="post" action="#" name="myform">
    <select name="x" onchange="myform.submit();">
        <option value="y">y</option>
        <option value="z">z</option>
    </select>
</form>

    All you have to do is give a name to your <form> and add the onchange event to your <select>...

    Adam is right. While the example above works perfectly, I would do it like this:

    Using jQuery but there are many other options available...

    <head>
<script type="text/javascript" src="jquery.js"></script>
<script>
    $(document).ready(function(){
        $('#mySelect').change(function(){
            myform.submit();
        });
    });
</script>
</head>

    and the form

    <body>
<form method="post" action="" name="myform">
    <select name="x" id="mySelect">
        <option value="y">y</option>
        <option value="z">z</option>
    </select>
</form>
</body>

    Change your select menu to this:

    <select name="bmsid" onchange="document.forms['changebmsid'].submit()">

    Update

    Here's another possible approach:

    <script type="text/javascript">
    window.onload = function() {
        document.forms['myform'].addEventListener('change', function() {
            this.submit();
        }, true);
    };
</script>

    Put that anywhere on your page, and you can leave you form as it is.
