VB.net Error in convering code behind a form from C# to VB.net

Hi

I am trying to convert the C# code at the bottom to the VB.net code just above.
I have one error at the line:
  Me.toolStrip1.LocationChanged = Sub(sender As Object, e As EventArgs) Me.panel1.Height = Me.toolStrip1.Top
The error is
Error      1      'Public Event LocationChanged(sender As Object, e As System.EventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.      C:\Users\murbro\documents\visual studio 2010\Projects\Infra_WinForms\Infra_WinForms\Form1.vb      22      9      Infra_WinForms
