Huzz,

You cannot. A page exist in the client as one page.
It is not a windowsform way of using that.

However when you want to do functions which you want to do in your complete
application, than you can make a seperated (shared/static) class for that,
which holds the methods you want to do.

Something as the sample bellow.

\\form class
Private Sub Form1_Load(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles MyBase.Load
       butt.colorbut(Me.Button1)
   End Sub
End Class
Friend Class butt
   Friend Shared Sub colorbut(ByVal but As Button)
       but.BackColor = Color.Red
   End Sub
End Class
///

I hope this helps?
