    RegisterHiddenField doesn’t create a server side control, it just
    creates a plain-old <input type="hidden" name="myhiddenField">

    Page.FindControl("myhiddenField") will never find anything on serverside and even document.getElementById("myhiddenField") will return nothing on clientside since only the name and not the id is assigned.

    So if you need to access it on serverside, you should use a HiddenField server control or at least use a html-input type=hidden with runat="server".
