You can do this using JQuery

 <select id="idXYZ" name="XYZ" onchange="SetUnit(this.value)">
 <%=  ViewData["YourValue"]%>
</select>

Now use JQuery

<script type="text/javascript">
function SetUnit(unit) {
        $.post("/Admin/YourMethod?itemid=" + unit.toString(), function(data) {
            var data = eval('(' + data + ')');
            $("#idunit").html(data.Value);
        });
    }

</script>

Are you using JQuery? You could use $.post to post your data in the onchange event... I think in the web forms way it was using a _doPostBack call in the onchange event if you set AutoPostBack to true... not 100% sure about that.
