Änderung durch Webservice-Aufruf nach Postback beibehalten

[wolfchr3]

Hallo!

Auf meiner aspx-Seite ist ein Dropdownlist-Control vorhanden. Über ein Webservice und Javascript verändere ich den Inhalt der Dropdownlist.
Führe ich danach ein Postback durch (Wizard-Control), sind die neuen Werte wieder verschwunden.
Ich denke im Viewstate sind nur die alten Werte gespeichert.
Wie erreiche ich, dass die neuen Werte permanent gespeichert werden?

    <script type ="text/javascript" language="javascript">
        //Teambereich Sichtbarkeit
        function TeamRegSichtbar(pWert) {
            document.getElementById("<%=C_3cNName_TextBox1.ClientID%>").value = '';
            document.getElementById("<%=C_3cVName_TextBox1.ClientID%>").value = '';

Speichere die Werte mittels JavaScript in Cookies und dann nach PostBack ließ die Werte aus.
