ASP.NET

As per topic, Has anyone got idea on how to dynamically change the attribute value of web form user control called 'commandValue' which is also known as public variable declared in user control. I need to know how to refresh div's content from changes.

<div id="MachineName" style="display:none" >
  <uc1:MachineNameControl runat="server" ID="MachineNameControl" commandValue =""/>
</div>

$("#MachineName").dialog({
                autoOpen: false,
                width: 450,
                height: 560,
                title: "Select a Machine",
                modal: true,
                buttons: {
                    "Back to Depart Group": function () {

                    },
                    Close: function () {
                        $(this).dialog('close');
                    }
                },
            });


$("#MachineName").dialog('open');
$("#MachineName").parent().appendTo($("form:first"));
