Web control library VS 2005 problems after switching from design viewto source view

[Christian]

Hi all,

i already posted this in dotnet.vb.contr ols but i need some help, so i
cant wait...

I have written a web control library and have some problems with it.
The Library contains only two Controls: a menu bar and a menu item
class which can have sub items (from the same class and type).
It also has a designer class which should show the control in design
time.
If i put the contron in design view on the page, everything works
(changing sizes,
adding MenuItems / Submenu items) and the data can be modified by
using the
VS Controls but if i switch to source view and back, all information
about the menuitems
are lost (but they still exist in the source view).
I have tryed to debug it, but it seams that the class will be
recreated and does not get
the information about the items and subitems, the list count is 0
after switching back to
design view.
here some code:
<ToolboxData("< {0}:WebMenuBar runat=""server" "></
{0}:WebMenuBar> "),
_
DisplayName("We bMenuBar"), _
ParseChildren(T rue, "MenuItems" ), _
DefaultProperty ("MenuItems" ), _
Description("A menu control which acts like the menus in
applications"), _
Designer(GetTyp e(WebMenuBarDes igner))_
Public Class WebMenuBar
Inherits CompositeContro l
----snip ----
Private m_List As List(Of WebMenuBar_Menu Item)
----- the property which gets the menu list
<Category("Data "), _
Description("Me nuItems collection"), _
DesignerSeriali zationVisibilit y(DesignerSeria lizationVisibil ity.Content),
_
PersistenceMode (PersistenceMod e.InnerDefaultP roperty)_
Public ReadOnly Property MenuItems() As List(Of
WebMenuBar_Menu Item)
Get
If m_List Is Nothing Then
m_List = New List(Of WebMenuBar_Menu Item)()
End If
OutputDebugStri ng("GET: Public ReadOnly Property
WebMenuBar::Men uItems() As List(Of WebMenuBar_Menu Item) count = " &
m_List.Count.To String())
Return m_List
End Get
End Property
---snip-----
VisualStudio also wants me that i create 2 functions with the name of
the class as propertys,
but i dont know for what and why, what should i return there ?:
Public ReadOnly Property WebMenuBar() As WebMenuBar
Get
OutputDebugStri ng("GET: Public ReadOnly Property
WebMenuBar() As WebMenuBar")
Return m_WebMenuBar
End Get
End Property
Public ReadOnly Property WebMenuBar_Menu Item() As
WebMenuBar_Menu Item
Get
If m_List.Count <= 0 Then
OutputDebugStri ng("GET NEW: Private Property
WebMenuBar_Menu Item("") As WebMenuBar_Menu Item")
Return New WebMenuBar_Menu Item()
Else
OutputDebugStri ng("GET: Private Property
WebMenuBar_Menu Item("") As WebMenuBar_Menu Item")
Return m_List(0)
End If
End Get
End Property
Does anybody can help me ?
Kind regards
Christian
