Dim instance As IStateManager 
Dim returnValue As Object

' Implement the SaveViewState method. If the StateBag 
' that stores the MyItem class's view state contains 
' a value for the message property and if the value 
' has changed since the TrackViewState method was last  
' called, all view state for this class is deleted,  
' using the StateBag.Clear method,and the new value is added. 
Function SaveViewState() As Object Implements IStateManager.SaveViewState
    ' Check whether the message property exists in  
    ' the ViewState property, and if it does, check 
    ' whether it has changed since the most recent 
    ' TrackViewState method call. 
    If Not CType(_viewstate, IDictionary).Contains("message") OrElse _viewstate.IsItemDirty("message") Then
        ' Add the _message property to the StateBag.
        _viewstate.Add("message", _message)
    End If 
    Return CType(_viewstate, IStateManager).SaveViewState()
