I have two menus in a user control that are sharing the same SiteMapXmlFile. I'm attempting to use the RenderRootItemId to show the submenu of what is selected in the first menu control. for both menus. It renders correctly on first load but on a postback I receive an error "No Item found with Id 'L2Reports'". Here is the html markup (nothing in code behind). I've tried version 2009.2 and 2009.3 with same results. 

<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="Menu.ascx.vb" Inherits="RBC.Website.Menu2.Menu" %>
<%@ Register Assembly="ComponentArt.Web.UI" Namespace="ComponentArt.Web.UI" TagPrefix="ComponentArt" %>
<div>
    <ComponentArt:Menu ID="MenuLevel1" runat="server" RenderDrillDownDepth="1" DefaultItemLookId="Unselected" DefaultSelectedItemLookId="Selected" DefaultChildSelectedItemLookId="Selected" AutoPostBackOnSelect="true" SiteMapXmlFile="~/MenuN.xml">
    </ComponentArt:Menu>
</div>
<div>
    <ComponentArt:Menu ID="MenuLevel2" runat="server" RenderRootItemId="L2Reports"  RenderDrillDownDepth="1" DefaultItemLookId="Unselected" DefaultSelectedItemLookId="Selected" DefaultChildSelectedItemLookId="Selected" AutoPostBackOnSelect="true" SiteMapXmlFile="~/MenuN.xml">
    </ComponentArt:Menu>
</div>

Hello,

 

Thank you for submitting your query with ComponentArt Forum.

 

In order to overcome this the Viewstate has to be turned off for the menu as follows:

 

 

 

<div>


<ComponentArt:Menu ID="MenuLevel2" runat="server" RenderRootItemId="L2Reports" RenderDrillDownDepth="2" DefaultItemLookId="Unselected" DefaultSelectedItemLookId="Selected" DefaultChildSelectedItemLookId="Selected" AutoPostBackOnSelect="true" SiteMapXmlFile="~/MenuN.xml" EnableViewState
="false">


</ComponentArt:Menu>

</div>

I was hoping there was another solution or that I was simply doing somethng wrong. The only problem with this is that the menu loses it's state. It doesn't remember which item is selected during a page postback and wont show the right styles. The menu isn't using the navigate-url attribute either as everything is loaded on the same page (not my design). I was hoping for another solution. I suppose I can keep track of which item is selected in the usercontrol that is hosting the component art menus.

Thanks
