VB silverlight for windows phone “Handles clause requires a WithEvents variable defined in the containing type or one of its base types”

问题

When I am selecting a button from the .xaml file and then tap event from the right (in order to set the tap event) it auto generates this sub:

Private Sub btn(ByRef sender As Object, e As System.Windows.RoutedEventArgs) Handles btn.Tap

End Sub

But it also has this error:

Error 1 Handles clause requires a WithEvents variable defined in the containing type or one of its base types.

Any suggestions? Thank you!

Public WithEvents btn As Button just above the sub in order to send away the bug !
