asp.net - Google Language Dropdown Widget - On Ajax Page -


i have google language drop-down widget on asp.net page. page contains cascading drop-downs. is, on selection of value first drop-down, fill other.

the problem facing is, if select language first google language drop-down , change value first drop-down, values in second drop-down not persisting changed language. sure happening because of async postback. but, if enableajax property false, working. using telerik radajaxmanager implement ajax. please find code attached here 

<html xmlns="http://www.w3.org/1999/xhtml">     <head runat="server">         <title>test page - asp.net</title>     </head>      <form id="form1" runat="server">         <asp:scriptmanager runat="server" id="scrpt1">         </asp:scriptmanager>     <telerik:radajaxmanager id="radajaxmanager1" runat="server" enableajax="true">             <ajaxsettings>                 <telerik:ajaxsetting ajaxcontrolid="ddl">                     <updatedcontrols>                         <telerik:ajaxupdatedcontrol controlid="dropdownlist2" />                     </updatedcontrols>                 </telerik:ajaxsetting>             </ajaxsettings>         </telerik:radajaxmanager>         <div>             <div id="google_translate_element">             </div>              <script type="text/javascript">                     function googletranslateelementinit()                      {                         new google.translate.translateelement({ pagelanguage: 'en', layout: google.translate.translateelement.inlinelayout.simple}, 'google_translate_element');                     }             </script>             <script type="text/javascript" src="//translate.google.com/translate_a/element.js?cb=googletranslateelementinit"></script>             <br />             <br />             <asp:dropdownlist runat="server" id="ddl" autopostback="true">                 <asp:listitem text="a"></asp:listitem>                 <asp:listitem text="b"></asp:listitem>                 <asp:listitem text="c"></asp:listitem>                 <asp:listitem text="d"></asp:listitem>             </asp:dropdownlist>             <br />             <br />             <asp:dropdownlist runat="server" id="dropdownlist2" />         </div>         </form>     </html>

code behind 

          private sub ddl_selectedindexchanged(byval sender object, byval e system.eventargs) handles ddl.selectedindexchanged              dropdownlist2.items.add(ddl.selecteditem.text)         end sub

please let me know if can achieve ajax enabled.

thanks, srinivas
