The Code Project - TreeListView

Hi All.

I'm looking for a control to use in VB.NET 2005 that merge a Listview
functions with a Treeview. A good example is this one:
http://www.codeproject.com/cs/miscctrl/treelistview.asp

The only problem is that after I've added a reference and also the control,
I can compile it, use it, work on it only one time in VB. After, when I want
to reopen the Designer to Edit the Form1 (that contains the control) I
receive an error:
--------------------------------------------------
"One or more errors encountered while loading the designer. The errors are
listed below. Some errors can be fixed by rebuilding your project, while
others may require code changes. "
The variable 'TreeListViewItemCollectionComparer1' is either undeclared or
was never assigned.
The variable 'TreeListViewItemCollectionComparer1' is either undeclared or
was never assigned.
--------------------------------------------------

The Designer doesn't start.
I' ve tryed to cut the code directly into the Form1.Designer.vb (I know that
I can't) and after I've removed the code of
TreeListViewItemCollectionComparer1 definition I can reopen the Designer
correctly. Obviously when I modify any proprieties the Designer Re-Write the
Form1.Designer.vb and introduce on it the same error.

Last thing. Very Important. This happen only with VB project. If I use this
control in a C# project all work fine.

Any Suggestions???
Thank a lot.
