    if (e.MiddleButton == MouseButtonState.Pressed)
    {

        MessageBox.Show("The Middle Mouse Button is pressed");

        MessageBox.Show("The XButton2 Mouse Button is pressed");

}
Private Sub MouseDownHandler(ByVal sender As Object, ByVal e As MouseEventArgs)
    If e.RightButton = MouseButtonState.Pressed Then

    End If

    If e.XButton1 = MouseButtonState.Pressed Then
        MessageBox.Show("The XButton1 Mouse Button is pressed")
