Thanks for your reply admlange.

here is my source .ascx file

I call the control file from admin/skin folder. when i run this source i didn't get any error. When I Convert PA i got the above error. 

 <%@ Control language="vb" Inherits="YourCompany.Modules.PageMenu.ViewPageMenu" CodeFile="ViewPageMenu.ascx.vb" AutoEventWireup="false" Explicit="True" %>
<%@ Register Src="../../admin/Skins/nav.ascx" TagName="nav" TagPrefix="dnn" %>

<dnn:nav ID="SiteNav" runat="server" ProviderName="DNNMenuNavigationProvider" 
  CSSControl="main_dnnmenu_bar" 
  CSSContainerRoot="main_dnnmenu_container" 
  CSSNode="main_dnnmenu_item" 
  CSSNodeRoot="main_dnnmenu_rootitem"  
  CSSBreak="main_dnnmenu_break" 
  CSSNodeHover="main_dnnmenu_itemhover"  
  ControlOrientation="horizontal"
  IndicateChildren="false"
  NodeLeftHTMLSub="&nbsp;&nbsp;"
  NodeRightHTMLSub="&nbsp;&nbsp;">
  </dnn:nav>
 

Code behind is as follows:

Dim menuOrientaion As String="Horizontal"

Dim CusAt As DotNetNuke.UI.Skins.CustomAttribute
  CusAt = New DotNetNuke.UI.Skins.CustomAttribute
  CusAt.Name = "submenuorientation"
  CusAt.Value = menuOrientaion
  SiteNav.CustomAttributes.Add(CusAt)

Thanks for again admlange your reply.

 

  Thanks for this admlange,

I had workout your idea but no luck. I think we have the problem from control we called. actually we are using the controls like label, url are already converted PA from DotNetNuke. But the "admin/Skins" folder contain source only. so we will use these controls and converted PA packages and installed, the website contain the dll and source on the skins folder. this may be give error i thing.
