Property. Control or View State?


Hello,

I am creating a control which I will compile in a class.
I am having problems when I use a property in the View State:

    ' Items
    <Bindable(True), Category("Data"), DefaultValue(""),
Localizable(True)> _
    Property Items() As Generic.List(Of String)
      Get
        If ViewState("Items") Is Nothing Then
          Return New Generic.List(Of String)
        Else
          Return ViewState("Items")
        End If
      End Get
      Set(ByVal Value As Generic.List(Of String))
        ViewState("Items") = Value
      End Set
    End Property ' Items

But I don't get problems if I use it in Control State:

    Private _Items As New Generic.List(Of String)
    Public Property Items() As Generic.List(Of String)
      Get
        Return _Items
      End Get
      Set(ByVal value As Generic.List(Of String))
        _Items = value
      End Set
    End Property ' Items

Anyway, this is a little bit confusing to me.
Could someone tell me which one should I use?
I am working on ASP.NET 2.0.

Thanks,
Miguel

I guess all the problems are caused by continuous creation of a new
List object
every time you ask for Items property. Try this:

Property Items() As Generic.List(Of String)
  Get
    If ViewState("Items") Is Nothing Then ViewState("Items") = New
Generic.List(Of String)
    Return ViewState("Items")
  End Get
  Set(ByVal Value As Generic.List(Of String))
    ViewState("Items") = Value
  End Set
End Property
