partial postback doesn't work as expected

Silverlight

Hi, do you please have any idea how to convince that thing below that the partial postback could run but without refreshing of that silverlight control? To update div2 would be enough.

This is the structure of the code:

<telerik:RadAjaxManagerProxy  runat="server" ID="ajaxManagerProxy">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="div1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="div2" UpdatePanelRenderMode="Inline" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManagerProxy>


<div id="div1">
 RadTabStrip1 "event OnTabClick is defined"....
 RadMultiPage1...
  PageView1 ....
  PageView2 ....
    <table>
      <td><tr>
       <asp:Panel ID="PanelForSVPlugin" runat="server">
         <object id="SilverlightPlugin" ......>
 .....

</div>


<div id="div2">
      RadTabStrip2....
      RadMultiPage2...
</div>
