الحل هو وضع كود في LOAD الخاص بالفورم 

كود :

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
FORM1.Controls.Add(butn)
       butn.Dock = DockStyle.Left
end sub

الكود كامل

كود :

Public Class Form1
Dim butn As XControl1
   Sub New()
       InitializeComponent()
       butn = New XControl1
       AddHandler butn.Button1.Click, AddressOf Button1CLICKHANDLER
       AddHandler butn.Button2.Click, AddressOf Button2CLICKHANDLER
       AddHandler butn.Button3.Click, AddressOf Button3CLICKHANDLER
       AddHandler butn.Button4.Click, AddressOf Button4CLICKHANDLER

   End Sub
   Private Sub Button1CLICKHANDLER(sender As Object, e As EventArgs)
       '========= هناء يتم كتابة الكود  جديد
   End Sub
   Private Sub Button2CLICKHANDLER(sender As Object, e As EventArgs)
       '========= هناء يتم كتابة كود الحفظ
   End Sub


Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
FORM1.Controls.Add(butn)
       butn.Dock = DockStyle.Left
end sub
