JScript error with adding menu items in codebehind?

[TSCGlobal]

I was recently working with adding menu items in a vb.net code behind based on a user's role.  The item was added to the menu, but the code gave birth to a weird error that I have no idea what it means, where it is, or how to address.  Any help is appreciated.

Here's the code behind;

'Determine user access, and load controls accordingly
If Roles.IsUserInRole(UserID, "Loss Prevention") = True Then

    'Create menu items
    Dim item As RadMenuItem = New RadMenuItem("Loss Prevention")
    Dim ChildItem As RadMenuItem = New RadMenuItem("I.P. Search")

    'assign all necessary menu item properties
    ChildItem.NavigateUrl = "~/LossPrevention/IPSearch.aspx"
    ChildItem.ImageUrl = "~/App_Themes/PanBlue/icons/SearchIcon1.png"

    'add menu items
    RadMenu1.Items.Add(item)
    item.Items.Add(ChildItem)
End If

When I run this app, I get a error that says; Microsoft JScript runtime error: 'undefined' is null or not an object (screen shot attached)

The best I can tell, this is a generated telerik code file that is screwing up somehow.  Any ideas on how to fix this?  I can't deploy the app with this issue.

Hello beemer,

I doubt this will help, but I would suggest adding the child item to the parent before adding it to the menu. Even through you have a reference to the parent item, it's not going to add the child item because you already added the parent item to the menu with no child items.

Thanks for the suggestion, however I did find the issue.  I had commented out a control (for troubleshooting purposes), but did not remove/comment out the control registry at the page directive.  Removing both also removed the issue.  Who would've thunk? lol.
