How to pass parameters from server to client in ajaxRequest?

[Vitalii]

I have button which launch ajax request. That button manage a panel.

<AjaxSettings>
    <telerik:AjaxSetting AjaxControlID="button_launcher">
        <UpdatedControls>
            <telerik:AjaxUpdatedControl ControlID="panel" />
        </UpdatedControls>
    </telerik:AjaxSetting>
</AjaxSettings>

I can change size of panel in server-side. But sometimes I need manage other elements which unavailable in server-side. So I want to calculate values and pass it to client-side and then make changes which I need to do. After long searching I did not find how to do that. Now I do it in ugly way - I write this parameters on hidden labels and then parse it in OnResponseEnd function. Can I avoid it somehow?
