$("#<%= hfWidth.UniqueID %>").val($("#drag").attr("offsetWidth"));
to fill the hidden field with client-side values
but when I do postback, the values doesn't seem to be saved.

If you want to get params from the server side, you should use name instead of id attribute.
And your code should work :
$("#elementId").val("value");

the .UniqueID is the value set to the name attribute of the object.

Can you provide us more code than that ? Because this code doesn't show sufficient info. Thanks.
fixed it with <%= hfWidth.ClientID %>

This is only possible after 2 days.

yep.. im stuck with this for 2days... who ever made that stupid rule?
in your aspx page:
<asp:HiddenField ID="hdn_checkbox" runat="server" />
in your Javascript:
function somefunction() {
$("#<%= hdn_checkbox.ClientID %>").val("test");
}
$('.btnGreen').click(function () {
somefunction();
alert($("#<%= hdn_checkbox.ClientID %>").val());
return true;
});
