Hi Tim,

I am facing the same chalange you had; I need to get the nodecollection so I can use it in my own custom menu. Copying part of nav.asx.vb (under admin/skins) and using it in a my own web control didn't help much. To keep it simple, for now I am want to display the node data in datalist on my web control and here is the code behind:

 

DotNetNuke.Entities.TabsDotNetNuke.UI.WebControls

Imports

DotNetNuke.UI.Navigation

Namespace

 

 

 

 

DotNetNuke.UI.Skins.ControlsPartial Class azkyteMenuInherits UI.Skins.NavObjectBase' protected controls

#

 

Region " Web Form Designer Generated Code "

<System.Diagnostics.DebuggerStepThrough()>

 

Private Sub InitializeComponent()End Sub

 

 

Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init'CODEGEN: This method call is required by the Web Form Designer

 

'Do not modify it using the code editor.

InitializeComponent()

 

End Sub

#

 

End Region

 

 

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.LoadTry

 

BuildNodes(

 

Nothing)Catch exc As Exception 'Module failed to load

ProcessModuleLoadException(

 

Me, exc)End Try

 

End Sub

 

 

objNodes = GetNavigationNodes(objNode)

 

 

Private Sub BuildNodes(ByVal objNode As WebControls.DNNNode)Dim objNodes As DNNNodeCollectionMe.Control.ClearNodes()'Me.Bind(objNodes)

 

 

Me.DataList1.DataSource = objNodesEnd Sub

End Class Namespace

End

 

The problem is I keep getting an error of "Object reference not set to an instance of an object." for the GetNavigationNodes(objNode) method. This part of the code is the same as nav.ascx.vb; any idea what is happening? Or if you could show me how you got NodeCollection data? Thanks for any help in this regard.
